A Counterpart for Fast Radio Bursts
Has a counterpart finally been detected for the ever-elusive fast radio bursts that have been detected outside of our Galaxy? Well, that’s a tricky question…
The changing star formation rate of the universe
The rate at which stars have formed in the universe has decreased over the last 10 billions years. Today, we examine how the electron density of star-forming regions in galaxies has evolved during that time.
Tidal Tails Tell Two Tales
Merging or interacting galaxies can form streams of gas and new star formation called tidal tails. Today’s paper explores the possibility that older stars from the original galaxies may also be pulled along into these streams.
Cosmic reionization: Who is to blame?
What caused the universe to shift from neutral to ionized as it expanded and cooled? Today, we examine clues that indicate it could have been the result of rapid star formation from the earliest galaxies.
Catching a small galaxy in the act of formation
A dwarf irregular galaxy in the Lynx-Cancer void is cannibalizing its neighbors.
