Relative motion of a compact binary system leads to a ‘beaming effect’ for gravitational waves and a systematic error in the inferred gravitational wave amplitude if unaccounted for.
Astrophysicists and their experiments normally look up, not down. IceCube is an exception. Here the density profile of the Earth is measured using neutrinos.
Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.
The first compelling association of an electromagnetic counterpart with an astrophysical neutrino since SN 1987A.
A laboratory astrophysics experiment calls into question the proposed dark matter origin of an unidentified spectral line at 3.5 keV
