Corpse too Bright? Make it Bigger!

The rare (un)lucky star dies by means of black hole, which shreds the star to bits before swallowing it. It’s a spectacular death to observe, but one which is less bright and hot than we thought they would be…

Black Holes Grow First in Mergers

By measuring the black hole mass and velocity dispersion of currently merging galaxies each in various stages of a merger, the authors conclude that the growth of the central super massive black hole occurs in the early stages of each merger and outpaces any bursts of star formation or central bulge growth.

Open Educational Resources for Astronomy

Today’s paper introduces a project called astroEDU. They’re aiming to make astronomy learning resources, like those you can find on Wikiversity, easier to find and of higher quality. To do this, the authors introduce a peer-review structure for education materials modeled on the one widely-accepted for scholarly research.

A New Type of Stellar Feedback

Reproducing the observed star formation history of galaxies in simulations is a fantastic test of our understanding of galaxy evolution. This is regulated strongly by “feedback”, for example, from supernova. Today’s astrobite discusses feedback from high mass X-ray binaries.

The Age of Solar System Exploration

The years of 2014 and 2015 may well be known as the time when our exploration of the solar system truly took off, as we explored asteroids, comets, and minor planets. Here’s a look back at what we’ve accomplished in the last year, and what we’re about to achieve in the year to come.
