The hunting of the chirp: a practical guide to 'hearing' the echoes of distant collisions of black holes and neutron stars using light

摘要

Gravitational waves from the collision of two massive black holes were detected by 2 Advanced LIGO interferometers in September 2015, which started the era of GW astronomy. In the talk, I will cover these unique machines and tell how they measured the shift of the mirrors by 1/100000th of a proton.
