Finding the Missing Bridges Between Galaxy Clusters
In today’s paper, the authors look for the more than 50% of matter in the universe that’s ‘missing’ from our count by searching for bridges between clusters of galaxies.
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.
A Sonic Boom (Half) as Old as Time Itself
That’s quite a sonic boom, particularly given that the speed of sound in the hot plasma is around 2 million miles per hour!
Galaxy Clusters, Cosmology, and Beethoven’s No. 6
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.
The First-Ever Detection of the Kinematic Sunyaev-Zel’dovich Effect
Astronomers present the first-ever detection of the motion of distant galaxy clusters via an effect first theorized 40 years ago.
A preview of the SZ effect, observable with ALMA
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.
