1. Welcome For those students new to the course, welcome! The MSc in Astrophysics and the Postgraduate Certificate at QMUL is taught by members of the Astronomy Unit in the School of Mathematical Sciences. For more information about the group and our research, see our Web sites below.

The course director for both MSc and Certificate is Prof. Reza Tavakol (Room 456, Maths). He is normally available during his office hours (Please see the times posted on his office door) to discuss any issues relating to the course. In urgent cases he can be contacted via E-mail (R.Tavakol@qmul.ac.uk) or by phone (020-7882-5451) During the first Semester (Sep-Dec 2007), however, Prof James Lidsey (Room 455, Maths) will be standing in for him.

3. Structure of the course The MSc can be studied either part-time (at least two years) or full-time (one year). The Certificate is studied part-time for one year. Lectures take place on Tuesdays and Thursdays. Full-time students must attend all Lectures. Part-time MSc students who wish to complete in two years will need to attend all the Tuesday and Thursday evening lectures. If they wish to extend their studies over more than two years, they need not take all the evening courses in a given year but this will not entail any extra fees. Certificate students are encouraged to take all the Tuesday and Thursday evening courses. The MSc students must also undertake a Project and write this up to the form of a dissertation. The scheduling of lectures is laid out on the following pages, together with details of the study requirements for the MSc and Certificate, and short syllabuses for all the lecture courses.

For the most up-to-date information you should however refer to the Web pages, where any corrections or additions to this information will be made.

4. The MSc Astrophysics Project This information applies to full-time MSc students and part-time MSc students in their second year, on the MSc in Astrophysics.

The elements on which the award of an MSc is based are the end-of-year examinations and the project. The project is an important component of the MSc, corresponding to 4 units, and you should devote substancial effort to it during the year. The examinations and the project must both be passed for the award of the MSc and distinction can only be attained in the MSc if it is also attained in the project.

The project gives the student the opportunity to work independently and critically on the topic of interest to them. It may be a theoretical topic, a critical examination of the literature, or more occasionally it may involve computational or experimental work. In all cases the emphasis should be on the astrophysics within the field chosen. The relevance of the work in the wider context of the subject should be explained as part of the introductory section. The project will normally require the study of original papers and show evidence of critical assessment. It need not include original research by the student, but it will be regarded favourably if it does. The report should not normally exceed around 10,000 words. In assessing the project, the examiners will pay particular attention to clarity of presentation, evidence that the student has worked critically and independently. and adequacy of references to original papers. The student may be examined orally on the Project in some circumstances.

Students must choose a topic and find a supervisor by the beginning of January. Students are encouraged to propose on their own initiative a Project which reflects their enthusiams and then approach a potential supervisor to discuss the proposal. In case of any difficulties contact Prof.

Tavakol. A list of potential supervisors and their subject areas is provided in section 4.3.

It is important that you embark upon your project early in the year. You must obtain approval for your proposed project from a staff member who agrees to supervise it and complete a Project Registration Form in consultation with the supervisor who must sign the form. The completed form must be returned to Prof. Tavakol no later than Thursday 31 January 2008 You will be informed once the Project has been approved.

During the winter term you should contact your supervisor fortnightly and begin background reading on your topic. No later than Friday 28 March 2008 i.e. the penultimate week of the winter term, you should hand your supervisor a short (at least 2 page) detailed outline of the proposed structure of your project. This should include references to the papers that you will be discussing or building upon and a first draft of at least an introductory chapter setting out the background and goals of the Project. Please arrange a short meeting with your supervisor to discuss this in some detail by or during the last week of term.

During the summer (starting May) term your should continue to contact your supervisor fortnightly. You are expected to come to an understanding with your supervisor about your respective schedules and how and when you will interact. By the end of June you should have completed a draft of the bulk of the Project. This should cover the basic material and should be the 6

basis for your own critical or original contributions. You should discuss this with your supervisor and continue to contact him fortnightly.

Your Project should be substantially complete before the summer examinations. After the examinations you will only have to make final addditions and have the report typed and bound in the required format. For the opening hours of the Library over the Summer term see the Library Web site http://www.library.qmul.ac.uk In Section 4.2 you will find the required format of the report and references etc. Information regarding details of word-processing facilities available at QMUL will be provided at the introductory talk on the computing facilities at the start of term.

Two typed and spirally bound copies of the Project in the required format, plus an electronic version, must reach the Chairman of Examiners (Dr R. Donnison) no later than Friday 29 August 2008 THIS IS A STRICT DEADLINE. Requests for an extension must be made to the Chairman of Examiners and will only be granted in exceptional circumstances.

4.1 Guidelines for examiners marking the Project 1 The Project should be the work of the candidate.

2 Project markers will take into account: (i) The English style and manner of presentation of the project (ii) The readability and coherence of the project (iii) The difficulty of the subject matter (iv) The quality of the introduction and the reference list.

3 Projects should not normally exceed 10,000 words, excluding tables, diagrams and references. If a submitted report is longer than 10,000 words then this will be taken into account when awarding the final mark.

4 To justify a pass mark there should be evidence of at least one of the following: (i) The candidate appreciates the context of the work in relation to the subject and to the wider field of astronomy or astrophysics. (ii) The candidate has carried out a critical assessment of the current state of their chosen topic. (iii) The candidate has discovered new facts through original work in the chosen topic.

5 A distinction will only be awarded when at least two of the factors listed in 4(i)-(iii) are present to a marked extent.

4.2 Style of Project Reports The Project report should be printed (word-processed) in double spacing on one side only of A4 paper. Colour should not be used, except where essential in figures. Two copies must be provided.

The title page of your report must contain: title of project; your name; year of entry to MSc course; name of supervisor.

4.2.1 Referencing Referencing should be consistent and follow either of the following two forms A and B. References to papers should be made at appropriate points in the text, and a list of papers cited should be made in a reference list at the end of the report.

7

A. In text: “…as was shown by Smith and Jones (1997) and by …”

In reference list: Smith, A. B. and Jones, X. Y. (1997), Title of Paper, Ap.J., 413, 774-796. [the entries after the title are the journal abbreviation (in this example the Astrophysical Journal, then the volume number, then the first and last page numbers] If you need to refer to two papers by Smith and Jones both published in 1997, refer to them in the text and in the reference list as 1997a and 1997b.

B. In text: “… as has been shown (24,25,…) …”

In reference list: 24. Smith, A. B. and Jones, X. Y. (1997), Title of Paper, Ap. J., 413, 774-796.

Journal abbreviations should follow the conventions of one of the standard journals, see i.e. the Astrophysical Journal or the Monthly Notices of the Royal Astronomical Society. For a book or conference proceedings, either of the above forms may be used, but the entry in the reference list after the author, date and title should be one of the form: in “All About Astronomy”, IAU Symposium 421, p. 217, P. Q. Brown (ed.), Publisher’s Name.

Note: Many journals keep exactly to either A or B above. Others, however – probably the majority – omit the title of the paper and the last (but not first) page number. For projects this alternative is not encouraged, as part of a Project’s value lies in its referencing as a ready introduction to the subject.

4.2.2. Layout of Project Title page Abstract. At the beginning there should be a one-paragraph abstract outlining the project and summarising any conclusions.

Table of contents. There should be a table of contents giving chapter and subsection names, together with page numbers where they begin.

The first chapter should be an introduction explaining the aims of the project.

Reference list. The reference list should come at the end of the main body of the report. The use of appendices should on the whole be avoided, but if an appendix is necessary (e.g. for a program listing, or some data) then this should come after the reference list.

All pages should be numbered, either at the bottom or at the top.

4.2.3 Binding The Project report should be bound in spiral binders between covers. This can be done in the Office in the Mathematics Building (first floor) by arrangement with the Secretaries or your supervisor. A small charge to cover costs of this may be made.

4.3 Finding a project supervisor The following staff members may be willing to supervise a Project in the study area(s) indicated.

They can be contacted directly, either by going to their office in the Maths Department or by phoning their extension (indicated below) to arrange a time. Some of them will not be in a position to supervise more than one Project, so it in your interest to contact the most relevant person as soon as possible. Please feel free to consult the Course director if you are uncertain which supervisor is most appropriate.

Please note that when dialling from outside the College, the telephone numbers should be prefixed with 020 7882.

4. 4 Note on plagiarism Plagiarism is the act of representing the work of someone else as though it were one’s own, and can lead to dismissal from the College. All significant ideas, derivations, results, and conclusions that are not the student’s own should be attributed to their original source by an explicit reference at the relevant position in the text together with the corresponding entry in the bibliography. Text copied verbatim from papers, Web materials, etc., should be surrounded in quotation marks and referenced.

Normally such quoted text should be brief (at most a few sentences up to a single paragraph).

Textual passages not attributed to others should be in the student’s own words and phrasing and represent the views, synthesis, and/or results obtained by the student. Supervisors should be consulted concerning the appropriate level of referencing well in advance of the final submission, though final responsibility rests with the student. See also the notes in the Student Handbook on http://www.maths.qmul.ac.uk/undergraduate/handbook/discipline.shtml

5. Award of the MSc and Certificate Qualifications Information will be provided later.

5.4 Resits Students may resit an examination on a particular lecture course they have failed on the next occasion on which an examination is offered in that subject. Some courses alternate between day and evening, and the examinations in those subjects are generally during the daytime in years when the course is taught in the daytime and during the evening when it is taught in the evening (see also Section 6).

6. Term dates The teaching is divided into two semesters. The first semester teaching starts on Monday 24 Sep 2007 and runs until Friday 14 December 2007. The second semester runs from Monday 7 Jan 2008 until Friday 4 April 2008. Revision lectures will be organised by the individual lecturers.

Exams for all courses will be held in May and June. Daytime courses will be examined on weekdays; evening courses will be examined either on the evenings on which they were taught or on Saturdays. The College’s examination timetable is usually only available after Easter. Details will be circulated when available. We shall endeavour to give students as much notice as possible of the dates and times of examinations.

Evening lectures start at 6:30pm (or earlier when there are exercise classes) and finish by 9pm, with a short coffee break half-way through the evening.

All evening lectures are held in the Maths building, mostly in Room 103. For time and place of the day-time MSc Astrophysics lectures see the timetable.

7. Miscellanea of relevance to all students • • •

There is a pigeon hole for MSc students located in the mail room just off the Common Room (Room 102). Please check your pigeon hole and emails frequently.

Your student ID card acts also as your Library card. There will be Library & Information Induction tours. The times will be announced at the start of term.

We constitute an MSc Student-Staff committee as a liaison forum: please discuss among yourselves to elect a representative and let the course director know.

8. Items mainly of relevance to full-time students •

In addition to the courses listed earlier in this booklet and on the Web page, students are entitled to attend any other undergraduate or postgraduate courses. The course director can provide further details upon request.

•

All MSc and Certificate students will be issued with an electronic card that will allow them access to the Maths Building after the closure of the main door in the evenings.

•

The study room for MSc students is Room 303. The electronic card for the front door will also allow access to this room. This room also contains computing facilities for MSc students. You will be given an account on these machines during the introductory talk on the computing facilities.

•

The Common Room is only available for MSc students (a) for access to the pigeon holes; (b) on Tuesday and Thursday evenings for students attending the evening Astronomy and Astrophysics lectures; and (c) by invitation by a member of staff. Coffee and other refreshment facilities are available in the Student Union building adjacent, also in Bar Med in the Library square and in the refectory building.

9. Library All students should attend the Library and Information Induction tour the timing of which will be announced at the start of the term. In addition to information about Library resources, you will also receive information about your Athens username, so you can access information resources on and off-campus. A wide variety of up-to-date library and information resources, including the Library catalogue and your own Library user record, can be accessed from any computer with access to the Web. Access the Main Library homepage: http://www.library.qmul.ac.uk/ and Kathy Abbott’s Finding Information: School of Mathematical Sciences Web page: http://www.library.qmul.ac.uk/eng/infopages/mathwww.htm In addition, for reference only, QMUL students can use the libraries at many of the other University of London colleges or the British Library at St Pancras. See the Web pages for information before you travel. For Main Library opening hours see http://www.library.qmul.ac.uk/ .

10. Seminars and the RAS All graduate students are encouraged to participate in College-based seminars and to consider joining the Royal Astronomical Society.

10.1 Astronomy Seminars There are Astronomy Seminars on Fridays during term time, currently starting at 2:15 pm. These are usually held in the Maths Seminar Room (Room 103 in the Maths Building). Full time MSc students are strongly encouraged to attend; part-time students are most welcome to attend if their schedules permit. The seminars cover a wide range of topics of current astronomical and astrophysical interest. A schedule of seminar speakers and titles for the term will be posted on the noticeboards, and can also be found at http://www.maths.qmul.ac.uk/Astronomy/seminar/astro.html Seminars do not take place on the second Friday of the month (October-May) because of Royal Astronomical Society meetings on those days.

10.2 Royal Astronomical Society The Royal Astronomical Society (RAS) is the principal professional organisation for astronomers in the UK. It is based at Burlington House, Piccadilly, and attractions of belonging to the Society include its monthly day-long meetings and use of the Society’s extensive library collection. The meetings are held on the second Friday of the month (October to May); usually there are parallel sessions, one on astronomy and the other on geophysics. We do not hold seminars on those Fridays, to avoid clashing with the RAS meetings. For meeting topics and venues, see http://www.ras.org.uk

There are various levels of membership, including Junior Member (for students under 26 years of age); Fellow for people 26+ years old; and a special category for those students too old for Junior membership but for whom the full Fellow’s membership fees would be difficult to pay.

Details of the current annual fees can be found on the Society’s Web site (http://www.ras.org.uk) To be elected to membership, you must be nominated by existing Fellows: most lecturers on the MSc course are Fellows of the RAS and would be happy to nominate you.

Forms for the appropriate level of membership can be found on the following pages of this booklet.
