Are there thousands of Godzillas hiding in plain sight?
A unique galaxy suggests a novel method to search for rare stars, which may have been previously overlooked and misidentified.
Sparkling Stars: Discovering Evolved Globular Clusters at High Redshift with JWST
Take a closer look at one of the galaxies in JWST’s first image and learn why it looks like it’s lighting up the party like a firework!
Reanalyzing LIGO-Virgo gravitational wave events under the new lens of… lensing!
Gravitational lensing can bend gravitational waves too! Do any of the recent LIGO-Virgo detections show evidence of lensing? Find out…
The Crowded Cosmos: Effects of Blended Galaxies on Cosmic Shear
In today’s paper, we learn how overlapping galaxies affect weak lensing measurements that the LSST will make.
Hidden monster or spooky cosmological coincidence?
Two binary black hole mergers were detected within 20 minutes of each other. But does this mean that there were four black holes… or just two?
Look! A Lensing!
Gaia can do astrometry very well. And it turns out it can also help us observe lensings.
