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.

Today’s astrobite explores one of the most extreme distant galaxies: a dusty, star forming galaxy at redshift 5.7 which has been found to have one of the highest star formation densities of any known galaxy in the Universe. But what causes this? Does it contain an active galactic nucleus?
The biggest and the brightest Lyα nebula is discovered! What can we learn from this giant?
