"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could ...

These jets become elusive the farther back in time astronomers try to look because of the so-called cosmic microwave background. The ancient radiation, the earliest fossil of light from 380,000 years ...

"Interestingly, the quasar powering this massive radio jet does not have an extreme black hole mass compared to other quasars." ...

From decades of astronomical observations, scientists know that most galaxies contain massive black holes at their centers.

Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have ...

Galaxies in a quasar state can release powerful jets from their active supermassive black holes. The jets can extend far into intergalactic space, even for millions of light-years. The process for ...

Astronomers have discovered a massive, double-lobed radio jet stretching 200,000 light-years from a quasar that existed when ...

Abstract: Quasars in the Age of Time-Domain Astronomy: Black hole feeding, visible as quasars, is a critical ingredient in many fields from galaxy evolution to multi-messenger gravitational wave ...

Scientists peering into the early universe are baffled to see lonely quasars drifting away in the void. Quasars are one of ...

Surprisingly, the black hole driving this colossal jet is modest by quasar standards, weighing 450 million times the mass of ...

As a result, they detected 19 strongly-lensed, dual and projected quasars. The finding was reported in a paper published Jan. 15 on the arXiv pre-print server. Quasars, or quasi-stellar objects ...
