An international team of astronomers has identified the farthest example of a rare class of gamma-ray emitting galaxies. The so-called BL Lacertae object was discovered…
Final Dance of Unequal Black Hole Partners Rochester Institute of Technology scientists perform first-ever simulation of large mass ratio black hole merger on Frontera. Solving…
Researchers from CIERA and the Center for Astrophysics | Harvard & Smithsonian put a limit on the spin of the supermassive black hole in the…
The monstrous black hole at the center of the Milky Way galaxy—now of Nobel Prize fame—is proving yet again to be stranger than fiction. New…
Andrea Ghez (Caltech MS ’89, PhD ’92), the Lauren B. Leichtman and Arthur E. Levine Professor of Astrophysics at UCLA, has won the 2020 Nobel…
Some supermassive black holes launch powerful beams of material, or jets, away from them, while others do not. Astronomers may now have identified why. Using…
A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using…
Astronomers have captured the last moments of a star just before it was ripped apart by a black hole. The violent occurrence—called a tidal disruption…
Using telescopes from the European Southern Observatory (ESO) and other organizations around the world, astronomers have spotted a rare blast of light from a star…
Andrea Ghez, UCLA’s Lauren B. Leichtman and Arthur E. Levine Professor of Astrophysics, today was awarded the 2020 Nobel Prize in physics. Ghez shares half of the…
Astrophysicist Andrea Ghez ’87 has been awarded the 2020 Nobel Prize in Physics, announced today by the Royal Swedish Academy of Sciences in Stockholm. She…
A team of gravitational-wave scientists led by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) reveal that when two black holes collide and…
Allowing for quantum corrections, the Einstein-Lovelock theory describes black holes with an equation that contains an infinite number of terms. However, according to a RUDN…
If a picture is worth a thousand words, what might the first horizon-scale image of a black hole tell us? A new paper by researchers…
Matter swirling around supermassive black holes creates bursts of light that “echo” in nearby dust clouds. These traveling signals could serve as a new cosmic…
Einstein’s description of gravity just got much harder to beat after astrophysicists put general relativity to a new test with black hole images. Einstein’s theory…
With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less…
Insight-HXMT, China’s first space X-ray astronomical satellite, has discovered a low-frequency quasi-periodic oscillation (QPO) above 200 kiloelectron volts (keV) in a black hole binary, making…
