Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the ...

When black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

In a groundbreaking study published on arXiv, astronomers from Seoul National University, South Korea, and collaborators across the globe have uncovered 62 new luminous quasars as part of the All-sky ...

The galactic cores, containing huge black holes, could help explain how the universe developed into the complex cosmos it is today. Reading time 2 minutes A team of astronomers has spotted the most ...

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 ...

Astronomers have crafted a map of the most powerful form of supermassive black holes across several billion light years of space. The three-dimensional map plots the locations of 1.3 million quasars, ...

A Yale-led team of astronomers has detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery, ...

Supermassive black holes appear to be present at the center of every galaxy, going back to some of the earliest galaxies in the Universe. And we have no idea how they got there. It shouldn’t be ...

Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had ...

Astronomers have discovered the longest radio jet so far in the early universe, spanning 200,000 light-years. Credit: NOIRLab / NSF / AURA / M. Garlick illustration Scientists have found a quasar ...

Quasars are the bright centers of young galaxies powered by supermassive black holes. Most quasars are very distant and faint, making them difficult to observe. One quasar, 0957+561, is ...

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 ...
