Why is the Temperature of the Universe Getting Hotter? - The Cosmic Companion Nov 17, 2020
The cosmic web - the largest structures in the universe - are growing hotter. Here's a look at why that happens
The temperature of the Universe is getting hotter, and the collapse of the largest structures in the Universe is behind it.
The cosmic web — ribbons of gas and dust tying galaxies together — are the largest structures in the Universe, and a new study shows they are growing hotter over time.
Utilizing a phenomenon known as the Sunyaev-Zeldovich effect, astronomers find these ribbons are three times hotter than they were eight billion years ago.
“Combining the latest data with a state-of-the-art theoretical model, we were able to reveal how the temperature of the Universe evolved, and how it was linked to formation of the large-scale structure of the Universe,” Ryu Makiya, a research fellow at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), explains.
