The central part of the total field of view of the VLA radio map of the Perseus cluster. NGC 1275 is the bright source in the middle of the image. The wide-angle tail radio galaxy NGC 1265 (NNW of NGC 1275) and the head-tail CR 15 (between NGC 1275 and IC 310), as well as IC 310 (WSW of NGC 1275) are clearly visible.

Astronomers Create Radio Map of Perseus Galaxy Cluster

Jan 4, 2021 by Sergio Prostak

Astronomers using NSF’s Karl G. Jansky Very Large Array have produced a high-resolution map of the Perseus cluster, a collection of thousands of galaxies...

Reynolds et al used Chandra to look for extraordinarily low-mass axion-like particles in the Perseus galaxy cluster, a group of galaxies located 240 million light-years away from Earth. The observation lasting over five days showed no evidence for certain axion-like particles, which some theorists think can explain dark matter. The lack of detection in these Chandra observations helps rule out some versions of string theory, a set of models intended to tie together all known forces, interactions, and particles.

This Hubble image shows young globular clusters (blue) and filaments of cool gas (red) around NGC 1275 in the center of the Perseus cluster (also known as Abell 426), a group of over 1,000 galaxies located 240 million light-years from Earth. Image credit: Lim et al, doi: 10.1038/s41550-019-0909-6.

Astronomers Find Thousands of Young Globular Clusters around Perseus Cluster’s Central Galaxy

Oct 29, 2019 by Enrico de Lazaro

Many thousands of compact and massive star clusters have formed at an approximately steady rate over the past one billion years around NGC 1275, the central...

This X-ray image of the hot gas in the Perseus Cluster was made from 16 days of Chandra observations. An oval highlights the location of an enormous wave found to be rolling through the gas. Image credit: NASA’s Goddard Space Flight Center / Stephen Walker et al.

Astronomers Find Enormous Wave of Hot Gas Rolling through Nearby Galaxy Cluster

May 2, 2017 by News Staff

A wave spanning 200,000 light-years (about twice the size of our Milky Way Galaxy) is rolling through the Perseus Cluster, according to observations from...
