FOCASing on the Metallicity Gradient of an Extremely Metal-poor Galaxy
Today’s authors explore a nearby analog of some of the earliest galaxies to form in the universe and measure a metallicity gradient.
UR: Phase Difference and Metallicity of RR Lyrae Variable Stars
In the latest of our #UndergradResearch series, explore how Anna McElhannon is investigating the relationship between pulsation and metallicity in RR Lyrae stars!
A story of light and darkness
There’s a problem with dark matter, and two possible solutions: bright, luminous supernovae, or dark matter itself.
UR: Are black hole progenitors missing in metal-poor environments?
In the latest of our #UndergradResearch series, read about the work by Beryl Hovis-Afflerbach on the environments in which binary black holes originate!
Globular Cluster Olympics: Who Will Win the Least Metals?
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.
UR: Modeling Chemical Abundance Evolution in Dwarf Galaxies
In the latest of our #UndergradResearch series, discover how Alexandra Kwon modeled the evolution of chemical abundance in dwarf galaxies.
