AGNs are among the most luminous and energetic sources in the universe. They are compact regions at the center of a galaxy, more luminous than the surrounding galaxy light, and very energetic due ...

A star’s destruction exposed something astronomers normally could not see: a dormant supermassive black hole about 30,000 light-years from the center of its apparent host galaxy. An ...

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 ...

Argentinian astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform high-resolution radio observations of a nearby spiral galaxy designated NGC 4527. Results of the ...

Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 ...

Active galactic nuclei (AGNs) are powered by accretion onto supermassive black holes and exhibit variability across the electromagnetic spectrum on timescales ranging from hours to years. Analysing ...

Active galactic nuclei (AGN) represent the energetic central regions of galaxies, powered by accretion onto supermassive black holes. A hallmark of many AGN is the presence of fast, ionised winds ...

A new study suggests that the mysterious little red dots discovered by NASA’s James Webb Space Telescope may represent a ...

An artist's rendering of what's called an active galactic nucleus at the center of NGC 4151. The galaxy's black hole sits at the center, immediately surrounded by an accretion disk shown in blue.
