Through the study of the optical to extreme ultraviolet radiation generated by the accretion of supermassive black holes at the centers of quasars, Associate Professor Cai Zhenyi and Professor Wang ...

The hearts of some galaxies glow so brightly that they are given a special name: Quasars. Powered by supermassive black holes at the center of these galaxies, these regions give off tremendous amounts ...

Maarten Schmidt, the Dutch-born American astronomer who explained the mysterious heavenly bodies known as quasars and in so doing helped create the modern picture of the universe, its structure and ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...

Space might seem calm when gazing up at the night sky, but invisible waves ripple continuously through the universe, bending space and time. These waves, known as gravitational waves, carry crucial ...

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 ...

Stephanie LaMassa did a double take. She was staring at two images on her computer screen, both of the same object — except they looked nothing alike. The first image, captured in 2000 with the Sloan ...

The galactic cores, containing huge black holes, could help explain how the universe developed into the complex cosmos it is today. Reading time 2 minutes A team of astronomers has spotted the most ...

An international team of astronomers reports the discovery of a new hyperluminous quasar. The newfound quasar, which received the designation eFEDSJ0828–0139, has a high star-formation rate and its ...

Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...

Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, according to observations from NASA’s Spitzer and Hubble space telescopes.
