When we don’t have spectra, we can estimate the distance to a quasar by calculating its photometric redshift. Today’s authors present a new way to use the ‘flickering’ of quasars to improve these distance estimates.
Today’s paper uses very deep JWST observations to hunt for some of the first galaxies ever formed!
In the latest of our #UndergradResearch series, study a pulsating variable star with Siddhesh Durgude.
The Euclid space telescope launched just over a year ago, and is already returning great science! In today’s bite, it’s looking at stars in the Perseus cluster that don’t belong to any galaxy.
Galaxy evolution is affected by a complex web of neighborhood politics between nearby galaxies. Today’s authors show that it’s the closest galaxies that matter the most in a galaxy protocluster!
Lurking behind a thick red blanket of gas, supermassive black holes are rapidly growing in very compact galaxies known as Little Red Dots, and they may hold some of the secrets of galaxy evolution.
