In fact, these jets often expand into wide plumes or “lobes” that fan out far above and below their host galaxies. The jets ...

A team of researchers led by York University Associate Professor Patrick Hall has discovered some strange behaviour occurring in distant galaxies, observing several cases of gas that is “falling” into ...

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 ...

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 spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the ...

Astrophysicists have developed a new method for pinpointing the whereabouts of extremely rare extragalactic objects. They hope their technique for finding 'changing-look quasars' will take scientists ...
