Examiner:

Professor  Marek Abramowicz



Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

The course is open to 4th/5th-year students (or students at an equivalent
level) and graduate students with background in physics and mathematics.

The course will be quite demanding, but not too difficult for those who are
determined to learn about the subject and are prepared for a serious effort.
Some knowledge of general physics, in particular special relativity, is
assumed. Knowledge of differential geometry and general relativity is not
required as the subject will be introduced during the course.

Aim

Black holes are fascinating objects. The course will cover all aspects of
black hole physics and astrophysics. In particular, important results
obtained by Stephen Hawking, Roger Penrose and others will be explainded in
details, including the most important ones concerning singularities and black
hole entropy. String theory explanation of black hole entropy will be
discussed.

It will be described how high-tech X-ray satellites, the Hubble Space
Telescope, and large radio telescopes, helped astronomers find several black
holes in the sky. Supermassive black holes found in centers of many
galaxies, including our own Galaxy, have masses millions to billions times
greater than that of the Sun. They provide power for quasars, the greatest
energy sources in the Universe. In a relatively small volume, comparable to
the size of a planetary system, a quasar generates energy at a rate thousands
of times exceeding the combined output of several billion stars that exist in
a galaxy. A scaled-down version of quasars, the stellar mass black holes,
were found in some binary systems in our Galaxy. They are only about ten
times more massive than the Sun.

Examination

Two possible ways. (1) An oral essay presentation in the classroom (during
the last week of the course). The subject must be agreed with examiners. Up
to two students may work on one presentation. (2) Written exam. Four
questions from a list of twenty will be asked at the exam. The list will be
announced two weeks before the exam.
