Uncovering black holes hiding in a globular cluster
A Milky way star cluster seems to contain more than the name suggests. How do astronomers find black holes hiding amongst stars?
The Fault in our Star (Populations): Solving the Multiple Stellar Populations Problem with Dark Matter
Globular clusters have puzzled astronomers with the presence of different distinct populations of stars; is dark matter a possible solution to this problem?
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.
Reconstructing the Galactic merger history with machine learning
Astronomers use machine learning to reconstruct past mergers that the Milky Way experienced.
UR: deepCR-ACS/WFC: Cosmic-Ray Rejection Model for HST ACS/WFC Photometry
In the latest of our #UndergradResearch series, discover James Kwon’s research on how deep learning is revolutionizing the removal of cosmic-ray contamination from Hubble images.
Searching for Milky Way Intermediate-Mass Black Holes with Hypervelocity Stars
The search for the elusive intermediate-mass black hole continues. Today’s authors present a novel method to search for Milky Way intermediate-mass black holes with the hyper-velocity stars they eject!
