Learning outcomes of the learning unit

These lectures will discuss the possible relationships between some key observables in astrophysics and the present status of particle physics, mainly concerning dark matter, inflation and black holes.
At the end of the course, students will be able:

1) to understand the modern concept of particle, and its dependence on the frame of reference;
2) to calculate particle creation effects associates with gravity;
3) to calculate the entropy of a black hole.

Prerequisite knowledge and skills

SPAT0060-1 or an equivalent course should be taken before this course.

Planned learning activities and teaching methods

This course is based on lectures,  and to discussion sessions where problems (see the course webpages for the list) are discussed, as shown in the table of contents. The problems will be solved by the students, under the guidance of the instructor. Preparing them is strongly advised.

Mode of delivery (face to face, distance learning, hybrid learning)

The references for each lecture, notes and the list of problems are available on the course web pages.

Organisational adjustments related to the current health context

Recommended or required readings

Viatcheslav Mukhanov and Sergei Winitzki, "Introduction to Quantum Effects in Gravity", Cambridge University Press, 2007.

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

written exam AND oral exam

- Remote

written exam AND oral exam

- If evaluation in "hybrid"

preferred remote


Additional information:

Written exam, followed by a discussion. The first question is on the theory, and the list of possible questions is available on the course web pages (it is subject to change during the year). The second question (given after the theory question is returned) is an open-book exercise. The written part lasts 2 hours.
If the colour code of the pandemic is yellow or green, the examination will be held in person. Otherwise, it will be held on Lifesize. One question sent at 9:00, answer expected by 11:30, followed by an oral exam in the afternoon.

Organizational remarks

The course will be organised in 10 one-and-a-half-hour lectures/discussion sessions (see contents).
