High Energy Astrophysics

  • 7.5 credits

Throughout this course you will get an overview over a number of high-energy processes and phenomena in the Universe.

Information for admitted students Autumn 2020

Congratulations! You have been admitted at Stockholm University and we hope that you will enjoy your studies with us.

In order to ensure that your studies begin as smoothly as possible we have compiled a short checklist for the beginning of the semester.

Follow the instructions on wether you have to reply to your offer or not.


Checklist for admitted students

  1. Activate your university account

    The first step in being able to register and gain access to all the university's IT services.

  2. Register at your department

    Registration can be done in different ways. Read the instructions from your department below.

  3. Read all the information on this page

    Here you will find what you need to know before your course or programme starts.


Your seat may be withdrawn if you do not register according to the instructions provided by your department.

Information from the department - courses

Everyone admitted to a course at the Department of Astronomy will receive a welcome letter with important information via e-mail. If you have not receive the mail by the beginning of August, please contact our study advisor!


Courses at the Department of Astronomy do not have a roll-call. Instead the course starts with the first lecture.


After being admitted to a course, you must register to confirm that you are starting your studies. For most of our courses this can be done online using your university account. Registration normally opens two weeks before the course starts and you must have registered at the latest one week after the first lecture. If you have any problems with registration, contact our student office. Contact details can be found below.

Click here to register online.

Learning platform

All courses at our department use the Athena learning platform. Once registered, the course should appear automatically in Athena. If you cannot find the course, contact the course coordinator.

Conditionally admitted

If you are conditionally admitted to a course at our department you need to contact our study advisor before you can register. Contact us as soon as possible, well before the course starts. Contact details are found further down on this web page.

Applicants on waiting list

Are you placed on a waiting list to any of our courses? You will always be contacted by e-mail if you  are offered a place. Normaly we will not admit new students if more than 1 week has passed after the firsts lecture.

Find the Departmend of Astronomy

All our courses are held in the AlbaNova building, located between the Frescati campus and the Royal Institute of Technology (Tekniska högskolan, KTH).

Find AlbaNova.

Education during autumn 2020

Most courses at the Department of Astronomy which starts during the first period of the autumn semester will have lectures given online while practical elements (e.g., laboratory exercises) and examination take place on campus.

More specific deatalis regarding this course can be found in the schedule or on the course page in the Athena learning platform. If you have questions you can contact the course coordinator; contact details are found further down on this web page.

Welcome activities

Stockholm University organises a series of welcome activities that stretch over a few weeks at the beginning of each semester. The programme is voluntary (attendance is optional) and includes Arrival Service at the airport and an Orientation Day, see more details about these events below.
Your department may also organise activities for welcoming international students. More information will be provided by your specific department. 

Find your way on campus

Stockholm University's main campus is in the Frescati area, north of the city centre. While most of our departments and offices are located here, there are also campus areas in other parts of the city.

In this course we will discuss a variety of “high-energy” phenomena that range from processes in compact binary systems over accretion onto black holes to the sources and detection of gravitational waves. Each time we begin by introducing (in some cases refreshing) the basic theoretical concepts, building a theoretical model and then confront the theoretical expectations with observations. The theoretical concepts contain elements from basic physics courses (e.g. classical mechanics or electrodynamics), gas dynamics and radiative processes. Knowledge in General Relativity is of course welcome, but not strictly needed for this course. The gravitational wave sources will be described by means of classical mechanics enhanced by additional effects. This course will allow you to apply fundamental physics concepts to understand some of the most violent events in the Universe.


  • Course structure

    The course is given during day time, and is part of the Master’s programme in Astronomy. The course is normally given in English.
