Another day, another interesting LIGO-Virgo-KAGRA detection! Find out why the extreme parameters of GW231123 create problems for gravitational wave modelers and may have some new information about black hole formation!
In the race to resolve the tension between cosmological and local measurements of the Hubble constant, another method enters the contest… using gravitational wave signals without an electromagnetic counterpart!!
There is a tradition in Astronomy to post silly science papers to the arXiv on Aprils Fools day. We’ve collected them all for 2026 and provided some “peer review”.
Galaxy-modelers beware! Today’s bite will guide you through an analysis of CEERS2-588, a quirky, UV-luminous, early galaxy discovered by JWST that’s causing issues in our theoretical models!
