This lecture course discusses topics complementary to my course on astroparticle physics taught in the summer term '23, which is therefore not a prerequisite. We will try to minimize repetitions. This course focuses mostly on high-energy astrophysics in a broad sense, with extensions into neighboring fields. We will cover a wide spectrum of topics ranging from radiative processes to compact objects, from cosmic accelerators to the promise of multi-messenger astronomy (gamma-rays, neutrinos, gravitational waves). We will omit classic stellar astrophysics, as there will be a focus course on this topic in parallel.
Contents:
High-energy Astrophysics
Here is a (preliminary) overview of the topics covered:
1. Introduction: Astronomical coordinates, distance measurements (may be skipped if generally known)
2. The high-energy sky
3. Radiative processes and radiative transfer
4. End phases of stars: Giants, supergiants, core-collapse supernovae
5. Stellar remnants: white dwarfs, neutron stars, stellar black holes
6. Binary systems and thermonuclear supernovae
7. Nucleosynthesis and chemical evolution
8. Cosmic accelerators: black holes with accretion disks and jets, shocks, and bursts (GRBs, X-ray bursters).
9. Cosmic diffuse emissions: Galactic continuum emission from CR, Positrons in the Galaxy, Indirect searches for Dark Matter, Cosmic diffuse background
10. The dawn of multimessenger astronomy: gravitational waves, cosmic neutrinos, gamma rays
Recommended reading list:
Will be provided at the beginning of the course.
