A Dark Matter Fossil Record: Using Geology to Probe Time-Varying Dark Matter Signals
Move over, dinosaurs — the search for fossilized dark matter is the new trend in (galactic) geology.

Find out how astronomers discovered a new stellar stream around the Milky Way in today’s Astrobite.
Supermassive black holes have a really nasty reputation for rendering galaxies uninhabitable, but this perception may be misguided. It’s possible that the radiation these vast beasts release while feasting could bring forth a bounty for life as we know it. Could organisms subsist on the light of an AGN sun?
Today’s guest post looks at the surviving galactic subhalos in simulations.
Ever wanted to take a peak into a Galactic archaeologist’s toolbox? Today’s authors take us on a great tour of theirs as they investigate several moving groups discovered pre-Gaia that may be part of the Milky Way halo!
A newly discovered Globular Cluster is one of the most massive and metal-poor in the Galaxy. In today’s paper, we examine the stars inside the cluster to see where it stands on the metal-poor podium.
