Using NASA's Chandra X-ray observatory, astronomers have performed deep X-ray observations of a nearby active galaxy known as NGC 5728 and its active galactic nucleus (AGN). Results of the observational campaign, published ...
An international team of researchers under the leadership of Dr. Florian Peißker at the University of Cologne's Institute of Astrophysics has discovered a very young star in its formation phase near the supermassive black ...
