In the article published today in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our Sun, formed so rapidly in ...

A whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has ...

A research team from the Yunnan Observatories of the Chinese Academy of Sciences has recently published a study in The Astrophysical Journal that examines the inner and outer broad-line regions (BLRs) ...

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, ...

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 ...

Blazars represent one of the most intriguing classes of active galactic nuclei, where relativistic jets are oriented close to our line of sight. This favourable geometry magnifies the observed ...

Astronomers looking into the early Universe have made a surprising discovery using the NASA/ESA/CSA James Webb Space Telescope. Webb’s spectroscopic capabilities, combined with its infrared ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

The first batch of alerts from the Vera Rubin Observatory drew attention to new asteroids, supernovae, and active galactic nuclei. Reading time 3 minutes The Vera C. Rubin Observatory spent the night ...

In 1963, Caltech researcher Maarten Schmidt had a eureka moment. He was looking at the spectrum of a mysterious object named 3C 273, a source that had been found and cataloged with then-novel radio ...

Morphological structure of the galactic outflow in VV 340a. This artistic rendering illustrates a multi-phase galactic outflow driven by a central active galactic nucleus. The white helix represents a ...
