A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability ...

Astronomers have used the wide-field view of the Dark Energy Camera to confirm that supermassive-black-hole-powered quasars in the early universe were packed into dense neighborhoods. However, it ...

With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images.

Astronomers observed ancient quasars that appear to be surprisingly alone in the early universe. The findings challenge physicists' understanding of how such luminous objects could have formed so ...

Astronomers using the James Webb Space Telescope (JWST) have unveiled a hidden population of supermassive black holes in the early universe that have never been seen before. This fascinating discovery ...

Pasadena, CA– Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies. Quasars are the extremely bright centers of galaxies surrounding ...

This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists’ understanding of ...
