Using the NASA/ESA Hubble Space Telescope and other space and ground-based observatories, astronomers have discovered SDSS J0749+2255, a closely bound...
The newly-discovered dormant black hole, named Gaia BH2, is orbited by a red giant star, and has a mass of 8.9 solar masses.
The location of Gaia BH2 and...
The newly-discovered ultramassive black hole has a mass of 32.7 billion solar masses and resides in the center of Abell 1201 BCG, a massive elliptical...
Astronomers have provided vital information in the global effort to understand GRB 221009A, one of the nearest and possibly the most-energetic gamma-ray...
It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed...
Ultramassive black holes with extreme masses of over 50 billion solar masses can be formed in the rare events that are multiple quasar mergers happening...
In 2015, astrophysicists for the first time detected gravitational waves, ripples in space-time that occur when neutron star or black hole mergers disrupt...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
Astronomers have examined data about 700 short gamma-ray bursts (GRBs) detected with NASA’s Neil Gehrels Swift Observatory, Fermi Gamma-ray Space Telescope,...
NGC 7469 is a very luminous, face-on barred spiral galaxy approximately 90,000 light-years in diameter.
This Webb image shows NGC 7469, a barred spiral...
Gaia BH1 has a mass of 9.62 times the mass of the Sun and is orbited by a bright Sun-like star at about the same distance as our planet orbits the Sun....
University of Queensland theoretical physicist Joshua Foo and his colleagues form the University of Queensland, Perimeter Institute and the University...
The newly-discovered black hole resides in the binary system Gaia DR3 4373465352415301632 with a main-sequence star that is slightly smaller than the Sun....
Using 18 all-sky maps produced by NASA’s Near-Earth Object Wide Field Infrared Survey Explorer (NEOWISE), astronomers have created what is essentially...
This is the first time such an effect, known as precession, has been seen in black holes, where the twisting is 10 billion times faster than in previous...
GRB 221009A, a gamma-ray burst detected on October 9, 2022, is one of the nearest and possibly the most-energetic gamma-ray burst ever observed. It occurred...
Astronomers have analyzed publicly available data from the Mid-Infrared Instrument (MIRI) on the NASA/ESA/CSA James Webb Space Telescope for three Seyfert...
Astronomers using the X-SHOOTER instrument at ESO’s Very Large Telescope (VLT) have detected light from a gamma-ray burst at a redshift of 6.3, meaning...
