3. A forest of gravitational waves in our Galactic Centre

Prof. Pau Amaro Seoane (Universitat Politècnica de València)

The Galactic Centre contains populations of stellar-mass and
substellar-mass compact objects orbiting the central black hole,
classified as early extreme-mass ratio inspirals (E-EMRIs) and extremely
large mass ratio inspirals (XMRIs). These systems constitute asymmetric
binaries, characterized by mass ratios exceeding 10,0000 to 1. This mass
differential causes the secondary body to...

1. Probing New Physics through Gravitational Wave Detection and Dark Matter Direct Detection

Numerous astrophysical observations indicate the existence of dark matter via gravitational effects, yet its nature remains elusive. Experiments exploring non-gravitational interactions between dark matter and Standard Model (SM) particles include indirect, direct, and collider detection. Meanwhile, gravitational-wave (GW) observations of compact binary coalescences since GW150914 also offer...
