A team of astronomers has used artificial intelligence to uncover seven new candidate quasars acting as gravitational lenses ...

Artificial intelligence narrowed more than 800,000 quasar observations to seven strong candidates for an exceptionally rare ...

Quasars are extremely luminous galactic cores where gas and dust falling into a central supermassive black hole emit enormous amounts of light. Due to their exceptional brightness, these objects can ...

In a new paper in The Astrophysical Journal, JILA Fellow Jason Dexter, graduate student Kirk Long, and other collaborators compared two main theoretical models for emission data for a specific quasar, ...

Astronomers observed ancient quasars that appear to be surprisingly alone in the early universe. The findings challenge physicists' understanding of how such luminous objects could have formed so ...

PARIS – The Euclid space telescope has spotted the oldest quasars – the brightest objects in the universe – ever discovered, deepening a cosmic mystery that has been puzzling scientists. Quasars are ...

This artist's concept depicts a distant galaxy with an active quasar at its center. The "quasar winds" are propelling hundreds of solar masses of material outward into the galaxy disk each year. This ...

A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of ...
