Particlebites reports on an emerging probe of cosmology and particle physics
Our sister site Particlebites covers a new detection of the kinematic Sunyaev-Zel’dovich effect.

That’s quite a sonic boom, particularly given that the speed of sound in the hot plasma is around 2 million miles per hour!
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.
Astronomers present the first-ever detection of the motion of distant galaxy clusters via an effect first theorized 40 years ago.
In order to prepare for ALMA observations, these authors make mock-observations of simulated data, and they show that ALMA will be an ideal observatory for studying galaxy clusters using the SZ effect.
Galaxy clusters trace the matter density of the universe, and by counting clusters as a function of mass and redshift, cosmologists can learn about the expansion rate of the Universe
