Astrophysics of Gravitational Wave Sources

NTMF090 – Astrophysics of Gravitational Wave Sources

LS 2019/2020: Wednesdays 10:40-12:10 in KVAS UTF

Previous years: LS 2018/2019

The goal of this class is to learn how to gain understanding of complex, unsolved problems with the origin and evolution of gravitational wave sources as a working example. The class will include order-of-magnitude exercises and literature reading. Credit will be given for class participation, homeworks, and final exam.

Class syllabus

  • Existing and future GW detectors and their sensitivities (LIGO, VIRGO, PTA, LISA)
  • Overview of existing detections in contrast to other known astronomical populations of compact objects
  • Evolution of single stars to compact objects (white dwarfs, neutron stars, black holes)
  • Evolution of binary stars to compact object binaries
  • Unconventional binary star evolution, dynamical formation of binaries (captures)
  • Physics of the merger
  • Electromagnetic and multi-messenger signatures of the merger
  • Introduction to the physics of astronomical transients
  • Core-collapse supernovae
  • The zoo of astronomical transients
  • Future sources: stochastic GW from big bang, white dwarf binaries, supermassive blackholes, EMRIs
