We can't see them directly, but we know they're there. Supermassive black holes (SMBHs) likely dwell at the center of every large galaxy. Their overwhelming gravity draws material toward them, where it collects in an accretion ...

The nearby lenticular galaxy NGC 5252 hosts extremely extended cones of ionized material. Recent observations conducted by an international team of astronomers have inspected these remarkable structures, providing important ...
By analyzing the data from various space telescopes, astronomers have performed a detailed study of an ultraluminous X-ray source known as NGC 2403 XMM4. Results of the study, published January 5 in the Monthly Notices of ...
An international team of astronomers reports the discovery of a large-scale structure that consists of at least 20 massive galaxies. The structure, dubbed "Cosmic Vine," has a size of about 13 million physical light years. ...
Recently, much attention has been given to massive, active galaxies discovered by the JWST in the early universe. But in contrast to these active galaxies, some galaxies that the JWST has discovered have been unusually quiet ...
