New bright high-redshift quasar discovered using VISTA

Using the Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have detected a new bright quasar at a redshift of about 6.8. The newly identified quasar, designated VHS J0411-0907, is the brightest object ...

Gravitationally lensed quasars

The path of light is bent by mass, an effect predicted by Einstein's theory of gravity, and when a massive galaxy or cluster lies along our line-of-sight to a more distant galaxy its matter will act as a lens to image the ...

Astronomers discover new luminous high-redshift quasar

An international team of astronomers has detected a new luminous quasar at a redshift of 7.02. The newly found quasi-stellar object (QSO), designated DELS J003836.10–152723.6, is the most luminous quasar known at a redshift ...

Two high-redshift quasars discovered using OGLE

Astronomers report the finding of two new high-redshift quasars using imagery from the Optical Gravitational Lensing Experiment (OGLE). The newly found quasars, designated OGLE J015531−752807 and OGLE J005907−645016, ...

A quiet Sunday night discovering a supermassive black hole

Earlier this year, on a quiet Sunday night, my colleague Jack and I found the fastest-growing supermassive black hole in the known universe. We were fortunate to be part of the team that made one of the greatest discoveries ...

Two bright high-redshift quasars discovered

Astronomers have detected two new bright quasars at a redshift of about 5.0. The newly found quasi-stellar objects (QSOs) are among the brightest high-redshift quasars known to date. The finding was presented May 9 in a paper ...

Double or nothing—astronomers rethink quasar environment

Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 "protoclusters," the progenitors of galaxy clusters, in the early universe, about 12 billion years ago, about ten times ...
