AS2001 Astronomy and Astrophysics 2
The AS2001 module is designed to complement and extend the knowledge gained in the first level module in Astronomy and Astrophysics, and to prepare the way for the more advanced topics encountered in a study of the subject at honours level. Lectures are based on the principles of physics together with mathematical techniques acquired earlier. It is intended that students should gain:
- a strengthening of the skills learned in AS1001/AS1101 and 1000-level physics and mathematics modules,
- a deeper understanding of the structure and evolution of stars, the design of telescopes and instruments for astronomical observations over the entire electromagnetic spectrum, the dynamical interactions of stars in the Galaxy, and exoplanetary science.
- a greater ability to analyse astronomical data, using the Python language and other computer packages.
AS2101 Astrophysics 2
This is as AS2001, but without the observational techniques lectures and the labs. This is normally taken only by accelerated entry students who are aiming for an astronomy degree. It can also be taken by a continuing student who is more interested in theoretical aspects of astronomy and who, having already taken AS1001, is keen to take an additional 2000-level 15-credit maths module in S2.

Tutorials and Workshops
Workshops and tutorials allow you to develop your problem-solving skills working with the lecture content. Some workshops and tutorials are run with a primary focus of developing specified relevant academic skills.
For Physics 2A/2B and AS2001 each student will typically attend one small group tutorial per week. These sessions are hosted by a designated tutor and allow students to work through tutorial problems and ask specific questions about the lecture material.
Students enrolled on Physics 2A and 2B will attend one workshop (problem solving class) each week.
Practical Work
For the Physics 2A and 2B modules students attend one afternoon session of 2½ hours (15:00 – 17:30) per week of practical work.
The aims of the second level practical work in physics are to build on previously acquired experimental skills while at the same time provide the opportunity for students to:
- work toward desired experimental outcomes but with greater freedom to explore the relevant topic;
- broaden competences in the use of various forms of experimental and diagnostic instrumentation;
- explore subject matter covered in lectures and, particularly in electronics, new material;
- develop skills in scientific writing.
Prior to the start of a practical you should familiarise yourself with the upcoming work and complete any pre-lab questions. Between lab afternoons you should complete any assignments, keep your data analysis and interpretation up-to-date, and prepare for upcoming work. We expect students to typically spend 7.5 hours per week on laboratory work.
At the start of 1st Semester (Physics 2A), the programme is slightly different for returning students and direct entry students, as direct entry students cover some of the lab skills development that has already been explored by our returning students, to gain a similar skill set and understanding of our expectations. In 2nd Semester (Physics 2B) all students will attempt the same programme of work. There is a choice of a physics experiments, followed by work in electronics and lab-related Python programming, and a scientific writing exercise. The module also includes an opportunity to see some of our research laboratories and relate the skills being developed in the teaching laboratory to those practiced by the experimental physics researcher.
For AS2001 Astronomy and Astrophysics 2 students also attend one astronomy laboratory sessions (15:00 – 17:.30) per week.
The aims of practical work in Astronomy and Astrophysics 2 are:
- to develop confidence in working with and interpreting astronomical data,
- to build programming skills and apply them to the analysis of astronomical data.
In all second level modules where practical assignments are to be handed in for marking according to a specified timetable, penalties will be applied for lateness up to and including the loss of all marks in particularly serious cases. Please see later in this handbook under Late penalties.
Mathematics revision
A good grasp of mathematics and its application to physics is essential for all students of physics and astrophysics.
During both the Physics 2A and Physics 2B modules, students will have the opportunity to complete online maths revision quizzes that encourage revision and practice of mathematical techniques which they have learned previously. These quizzes are supported by pre-recorded revision lectures.
