Using Atacama Large Millimeter/submillimeter Array (ALMA), researchers have conducted interferometric observations of the elliptical galaxy NGC 3557 to investigate molecular gas emission from this source. Results of these ...
Using data provided by NASA's Chandra spacecraft, astronomers have identified a new unusual ultraluminous X-ray source (ULX) in the elliptical galaxy Messier 86. The newly found ULX, designated M86 tULX-1, resides some 62,000 ...
Researchers often assume that massive galaxies host supermassive black holes (SMBHs) in their nuclei. In recent years, observers have sought galaxies that might contain an SMBH that is displaced from its equilibrium position. ...

The NASA/ESA Hubble Space Telescope caught sight of a soft, diffuse-looking galaxy that is probably the aftermath of a long-ago galactic collision. Two spiral galaxies, each perhaps much like the Milky Way, swirled together ...

The most massive galaxies in our neighbourhood formed their stars billions of years ago, early in the history of the universe. At the present day, they produce very few new stars. Astronomers have long believed that is because ...
