Using data from the REsolved Spectroscopy Of a Local VolumE (RESOLVE) and the Environmental COntext Catalog (ECO) surveys, astronomers have found evidence...

In this simulation of a supermassive black hole merger, the blue-shifted black hole closest to the viewer amplifies the red-shifted black hole in the back through gravitational lensing. Davelaar & Haiman discovered a distinct dip in brightness when the closest black hole passed in front of the shadow of its counterpart, an observation that could be used to measure the size of both black holes and test alternative theories of gravity.

In April 2019, the Event Horizon Telescope (EHT) Collaboration released stunning images of M87*, a 6.5-billion-solar-mass black hole in the center of the...

The four galaxies shown in this graphic are among 29 galaxies in the sample that showed evidence for growing black holes near their centers. X-rays from Chandra (blue) have been overlaid on optical images from the NASA/ESA Hubble Space Telescope of the galaxies NGC 1385, NGC 1566, NGC 3344, and NGC 6503. The boxes that appear in the roll-over outline the location of the burgeoning black holes. Image credit: NASA / CXC / Washington State University / Baldassare et al. / ESA / STScI.

Massive Black Holes Form in Dense Stellar Environments, Study Suggests

Black holes are demolishing thousands of stars in a quest to pack on weight, according to an analysis of images of 108 galaxies taken by NASA’s Chandra...

An artist’s conception of a dwarf galaxy, its shape distorted, most likely by a past interaction with another galaxy, and a massive black hole in its outskirts (pullout). The black hole is drawing in material that forms a rotating disk and generates jets of material propelled outward. Image credit: Sophia Dagnello, NRAO / AUI / NSF.
