Correlation-Dropping Into the Reionization Era
We still don’t know very much about the mysterious epoch of reionization. In today’s bite, learn about a new way to estimate when reionization started from a correlation drop!
The Universe’s Most Wanted Black Holes Finally Have an Alibi
GW231123 defies our best models of stellar collapse, hosting two black holes that shouldn’t exist. A new paper proposes a radical solution: these monsters may have been born in the early universe as primordial black holes, quietly feeding for billions of years until they became the record-breakers we detected today.
High-energy particles make radio signals in ice
Ultrahigh-energy neutrinos can be our gateway to studying some of the Universe’s most energetic but least understood phenomena. Today’s paper presents a proof-of-concept for a new, promising way to detect these ultrahigh-energy particles.
We’re Going to Steal the Moon (For Gravitational Waves)
The authors of today’s bite explore how lunar mountains and crust can act as the perfect detector for detecting ripples in spacetime.
Live fast die immediately – spinning black holes in collapsars
Core collapse supernovae sometimes lead to spinning black holes and gamma ray bursts. In this astrobite, we explore the results of a recent simulation of these “collapsar” systems to understand the impact of neutrino cooling on the black hole spin and subsequent gamma ray bursts.
Many Mergers Might Fill the Mass Gap
Did you know that many observed black holes theoretically shouldn’t exist? Today’s paper gathers gravitational wave evidence for how these impossible black holes might have formed.
