By analyzing the available observational data, astronomers from the Tribhuvan University in Nepal and elsewhere have ...

At a redshift of approximately 0.1, CIZA J0107.7+5408, or CIZA0107 for short, is a nearby, post-core passage, dissociative binary cluster merger. It is a large, roughly equal mass disturbed system ...

PLCKG287, also known as PSZ2 G286.98+32.90, is a galaxy cluster at a redshift of 0.38, with a mass of about 1.37 quadrillion solar masses and a temperature of 13 keV. The cluster has an X-ray ...

As the light was shifted towards the red end of the spectrum (lower frequency/longer wavelength) this phenomenon was termed 'redshift'. Figure caption, Lower diagram shows spectrum of light ...

Current programs include multi-wavelength observations of high redshift galaxy clusters to measure dark matter ... X-ray and Sunyaev-Zeldovich Confirmation of an Extremely Massive Cluster at Z=0.87, ...
