New Cosmological Detectives: Using FRBs to Constrain the Diffuse Gas Fraction
With an ideal dataset of many localized FRBs, how can the diffuse gas fraction in the IGM be constrained?
Localization of a Single Fast Radio Burst to a Massive Early-Type Spiral Galaxy
Previously it was revealed that FRBs may be coming from dwarf galaxies, but a new study by an Australian team reveals that they may originate from different places.
Astrobites at AAS 231: Day 2
We report on Day 2 of the winter AAS meeting in National Harbor, MD. Highlights include an exciting update on the repeating fast radio burst, a look at the evolution of galaxy clusters and what’s between them, and a summary of the state of gravitational-wave astronomy.
Meet the AAS Keynote Speakers: Lawrence Rudnick
Outreach extraordinaire, Lawrence Rudnick, employs both radio and x-rays to investigate the dynamics of the intercluster medium. Be sure to read this interview before his plenary talk at #AAS231 on Wednesday!
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…
No Home for A Fast Radio Burst… Yet
Mysteriously brief and extremely energetic radio signals are beamed at us thousands of times a day. We thought we finally figured out where one came from… or did we?
