Astrobites interviews Sean Carroll, one of the leading theoretical cosmologists of our time, about our universe, his new book and everything in between.
New supernovae measurements and precise distance calculations lead to an interesting conflict in cosmological parameters in the universe, depending on whether a tool is used to probe the local or the distant universe. Read on to find out how!
After learning about galaxy formation, computers can imitate millions of hours of calculations in just a few minutes.
This article explores the utility of galaxy clusters as a probe for precision cosmology, by reviewing some of the seminal literature in the field. Somewhere along the way, a symphony is heard.
By building a simulation that goes from the scale of galaxies down to individual rocky planets we come to the realization that the earth is unremarkable, but far from typical, challenging our Copernican world view.
In today’s astrobite, a group of astronomers experiences déjà vu while studying gravitational lensing.
