A Quick Tour Through Deep Space
Most of the matter in the Universe resides not in galaxies, but in an intergalactic filamentary network known as the “Cosmic Web.” The web includes both dark matter and ordinary (baryonic) matter, and it provides the raw materials for galaxy formation. Though the cosmic web is a critical component of the Universe, it is challenging to observe since it emits very little light of its own. I will describe how we study this material in deep space using the world’s most powerful telescopes and computers, what we currently know about it, and its connection to both cosmology and galaxy formation.
George Becker is an assistant professor in the UCR department of Physics and Astronomy. He received his PhD from Caltech, then did postdoctoral studies at the Carnegie Observatories and the University of Cambridge. He was an astronomer at the Space Telescope Science Institute before moving to UCR in 2015. His research focuses on the gas and dark matter in deep space, and how it connects to the formation of the first galaxies.
