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 ...

The cluster also contained enormous 200 quadrillion solar masses. "Quipu is a prominent structure readily noticeable by eye in a sky map of clusters in the target redshift range, without the help ...

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 ...

This is the metadata section. Skip to content viewer section. We characterize the distribution of quasars within dark matter halos using a direct measurement technique for the first time at redshifts ...
