Step into the cosmic house of mirrors at this quasar party at dawn!
Today’s guest post explores a galaxy whose mysterious clump is puzzling astronomers who are trying to pinpoint its origin.
Gravitational lensing can bend gravitational waves too! Do any of the recent LIGO-Virgo detections show evidence of lensing? Find out…
In today’s paper, we learn how overlapping galaxies affect weak lensing measurements that the LSST will make.
