ALMA Reveals Black Hole ‘Donuts’ Are Actually ‘Fountains’
Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive…
Scientists One Step Closer to Understanding Spiraling Black Holes
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions…
Astronomers Reveal Cold Molecular Gas Pumped by a Black Hole
Most galaxies lie in clusters containing from a few to thousands of other galaxies. Our Milky Way, for example, belongs to the Local Group cluster…
ALMA Views Galaxy-Scale Fountain in Full Glory
A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies…
GRAVITY Instrument Captures Observations of Material Orbiting Close to a Black Hole
ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky…
SOFIA Observations Reveal Possible Key to Black Hole Activity
Collimated jets provide astronomers with some of the most powerful evidence that a supermassive black hole lurks in the heart of most galaxies. Some of…
New Model Sheds Light on Spiraling Supermassive Black Holes
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions…
Black Holes Only Contain Small Percentage of the Universe’s Dark Matter
For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark…
XMM-Newton Observes Matter Falling Into a Black Hole
A UK team of astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in…
Looking Back in Time to Watch Massive Black Hole Formation
Black holes form when stars die, allowing the matter in them to collapse into an extremely dense object from which not even light can escape….
Chandra Discovers a Ring of Black Holes in Galaxy AM 0644-741
Astronomers have used NASA’s Chandra X-ray Observatory to discover a ring of black holes or neutron stars in a galaxy 300 million light years from…
Why This Supermassive Black Hole Appears to Move
The study, carried out by two researchers at the Instituto de Astrofísica de Canarias, shows that the “change in position” observed in the nucleus of…
Chandra Reveals Critical Evidence of Elusive Intermediate-Mass Black Holes
Scientists have taken major steps in their hunt to find black holes that are neither very small nor extremely large. Finding these elusive intermediate-mass black…
Further Evidence That Outskirts of Spiral Galaxies Host Massive Black Holes
Findings from a Rochester Institute of Technology study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are…
Astronomers Conduct Successful Test of Einstein Theory Near a Supermassive Black Hole
Astronomers conduct successful test of Einstein’s general theory of relativity near supermassive black hole. The massive black hole at the heart of the Milky Way…
VERITAS Confirms Neutrino Emission from Vicinity of Blazar TXS 0506+056
The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for…
Astronomers Trace Source of Cosmic Neutrino to Monster Black Hole
For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This…
