Researchers from the University of Arizona have recently discovered the most distant quasar to date. This finding allows researchers to answer how black holes can possibly grow. Quasars contain ...

Quasars acting as strong gravitational lenses are among the rarest finds in astronomy. Out of nearly 300,000 quasars ...

An international team of astronomers have employed the Spektr-RG spacecraft and various ground-based telescopes to ...

A team of European astronomers has used the European Southern Observatory’s (ESO) Very Large Telescope (VLT) and a host of other telescopes to discover and study the most distant quasar found to date.

The Extended Baryon Oscillation Spectroscopic Survey (eBOSS), the world's largest galaxy survey, is part of Phase IV of the Sloan Digital Sky Survey (SDSS), a major multi-spectral imaging and ...

There are several different kinds of redshift that we encounter in the universe. Those three are ‘gravitational’, ‘doppler‘ and ‘cosmological‘. Before looking at two examples, it is best to have a ...

Washington, D.C.-- Quasars--supermassive black holes found at the center of distant massive galaxies--are the most-luminous beacons in the sky. These central supermassive black holes actively accrete ...

Perhaps one of the most perplexing mysteries in current astrophysics is the science behind Quasars. Quasars, or “quasi-stellar radio sources” are the brightest and most distant star-like objects in ...

IT is often assumed that quasars are partaking in the general expansion of the substratum of an isotropic universe. This hypothesis requires that those quasars possessing any particular observational ...
