An international team of astronomers, including researchers at the Center for Astrophysics | Harvard & Smithsonian, has spotted the most distant astronomical object ever: a galaxy.

Active galaxy RXJ0134.2-4258 investigated in detail

Using XMM-Newton and NuSTAR satellites, astronomers have conducted a comprehensive, long-term multiwavelength study of an active galaxy known as RXJ0134.2-4258. Results of the observational campaign, published March 25 on ...

Supermassive black holes put a brake on stellar births

Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state-of-the-art simulations to back up results from a large sky survey, researchers ...

Colossal black holes locked in dance at heart of galaxy

Locked in an epic cosmic waltz 9 billion light years away, two supermassive black holes appear to be orbiting around each other every two years. The two giant bodies each have masses that are hundreds of millions of times ...

New giant radio galaxy detected

European astronomers report the detection of a new giant radio galaxy (GRG) as part of the LOFAR Two-meter Sky Survey (LoTSS). The newly found object, named Alcyoneus, turns out to be the largest GRG known to date. The finding ...

Supermassive black hole caught hiding in a ring of cosmic dust

The European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI) has observed a cloud of cosmic dust at the center of the galaxy Messier 77 that is hiding a supermassive black hole. The findings have confirmed ...
