4. Gravitational waves, astrophysical and collider phenomenology Tuesday - Session 3

Speaker

Andrea Mitridate (DESY)

Description

By tracking the arrival times of radio pulses from a collection of pulsars in the Milky Way, several pulsar timing array collaborations have found evidence for a background of gravitational waves permeating our galaxy. In this talk, I will present this evidence, review possible cosmological interpretations of the signal, and discuss ways to discriminate between the signals emitted by these cosmological sources and the one produced by black hole binaries.
