(Phys.org)—While peering into the nearby Triangulum Galaxy known as M33, astronomers have detected what appears to be a giant cloud of hydrogen around it. According to research published online on May 5 on the arXiv pre-print ...
A group of astronomers led by Sarah Bosman from the Max Planck Institute for Astronomy have robustly timed the end of the epoch of reionization of the neutral hydrogen gas to about 1.1 billion years after the Big Bang. Reionization ...
