MACHOs Find a New Weight Class to Compete In
In the past decade we have witnessed the rise and fall of primordial black holes as dark matter candidates. Today’s paper summary hints at their return in the coming decade.
UR #27 : Plucking the Web: Seeking Spider Pulsars Using a Jerk Search Algorithm
Today’s undergraduate research post is looking for ‘spiders’ in unidentified sources which emit gamma-rays.
Black holes – Do they grow stupendously large?
Black holes come in many different sizes. But is there a mass limit? The authors of today’s paper investigate the possibility of black holes a trillion times as massive as the sun. Surprisingly, they could also help explain the mysterious dark matter!
