In today’s paper, the authors test the theory that the earliest, metal-poorest stars are the primary source of binary black hole mergers.
Today’s authors explore a nearby analog of some of the earliest galaxies to form in the universe and measure a metallicity gradient.
In the latest of our #UndergradResearch series, explore how Anna McElhannon is investigating the relationship between pulsation and metallicity in RR Lyrae stars!
There’s a problem with dark matter, and two possible solutions: bright, luminous supernovae, or dark matter itself.
In the latest of our #UndergradResearch series, read about the work by Beryl Hovis-Afflerbach on the environments in which binary black holes originate!
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.
