In eight new papers, the North American Nanohertz Observatory for Gravitational waves (NANOGrav) presents evidence for a gravitational wave background. In this bite, we provide an overview of their results and their implications
“The past, present, and future of the Hubble tension”: We interviewed cosmologist Daniel Scolnic for his plenary talk at the upcoming #AAS242!
Today’s Astrobite seeks evidence of hypothetical dark matter – neutrino interactions in the Cosmic Microwave Background, and considers what effects such an interaction would have on the Standard Model.
Today’s paper investigates one of the galaxies helping to drive the process of reionization.
In 2022, we think of the Big Bang theory as a cornerstone of cosmology, but as recently as a few decades ago, scientists weren’t so sure. Today’s classic astrobite explores one of the final pieces of evidence that helped the Big Bang become the widely accepted idea it now is.
