In a strange, half-lost, piece of work Roger Penrose draws four figures dropping their lines into the depths of a black hole, and in doing so finds a new and hugely influential way to steal energy away from the heart of a spinning singularity.
Can we detect the signature of an AGN reionization?
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
Hot and fresh out the kitchen, today’s paper discusses a new way to measure physical properties of galaxies—including, for the first time, “star formation acceleration.”
X-ray studies of galaxy clusters tell us how the extremely hot gas is distributed within these gigantic structures. Looking at these clusters across different redshifts, what does one find?
…or are they? The color-mass diagram for galaxies can tell us a lot about galaxy evolution, and today’s paper reports what this diagram looks like at high redshifts.
