Juggling black holes in star clusters
Today’s authors explore a new formation channel for forming intermediate mass black holes!
“Revelio!” Hints of Supermassive Black Hole Mergers in Nuclear Star Clusters
Can we predict the presence of a supermassive black hole binary system at the centre of a nuclear star cluster ? Find out in today’s paper summary.
Gravitational Waves, à la General Relativity or Scrambled?
Have any gravitational wave signals been scrambled? Today’s authors search for this beyond-general relativity effect.
The April Fools Paper Review Process – 2023
There is a tradition in Astronomy to post silly science papers to the arXiv on Aprils Fools day. We’ve collected them all for 2023 and provided some “peer review”
The Trouble with Black Hole Wobbles
Today’s authors show that including nonlinear modes improves the black hole ringdown model and could be very important for gravitational wave data analysis.
Multi-messenger constraints on the Hubble constant
The Hubble tension remains a major open question in contemporary cosmology. Today’s paper addresses using gravitational waves and light from neutron star mergers to constrain the Hubble constant.
