An international team of astronomers has conducted a detailed study of a high-redshift young radio source designated J2102+6015. Results of the research, presented in a paper published August 4 on arXiv pre-print repository, ...
Large amounts of gas are sometimes funneled to a galaxy's nuclear regions, with profound consequences. The gas triggers starburst activity and can also feed the supermassive black hole, converting it into an active galactic ...

Using data from the Rossi X-ray Timing Explorer (RXTE) satellite, astronomers from the Florida Institute of Technology have discovered a quasi-periodic oscillation (QPO) in the galaxy NGC 4945. The finding, reported in a ...
An active galactic nucleus (AGN) is a supermassive black hole residing at the core of a galaxy that is accreting material. The accretion occurs in the vicinity of the hot torus around the nucleus, and it can generate rapidly ...

Astronomers have conducted photometric and spectroscopic observation of a changing-look Seyfert galaxy known as NGC 3516. During this monitoring campaign, the researchers detected a flare from this galaxy that may provide ...
Astronomers have performed observations of a galaxy known as RX J1301.9+2747 using ESA's XMM-Newton spacecraft. The study unveiled three strong and rapid X-ray quasi-periodic eruptions (QPEs) in the nucleus of this galaxy. ...
This swirling mass of celestial gas, dust and stars is a moderately luminous spiral galaxy named ESO 021-G004, located just under 130 million light-years away.

Using the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have investigated the infrared galaxy WISE J101326.25+611220.1 (or WISE1013+6112 for short). The researchers report that WISE1013+6112 is one ...
A project lead by an international team of researchers use publicly available data with images of the sky dating as far back as the 1950s to try to detect and analyse objects that have disappeared over time. In the project ...
