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…
Astronomers Investigate Supermassive Black Hole Radio Jet In Unprecedented Detail
In the centre of the galaxy OJ 287, there is one active, super-mass-rich black hole. An international research team led by Silke Britzen of the…
Astronomers Directly Image a Black Hole Ripping Apart a Star
For the first time, astronomers have directly imaged the formation and expansion of a fast-moving jet of material ejected when the powerful gravity of a…
New Evidence of the Existence of an Elusive Type of Black Hole
Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of…
Gemini Reveals Outflowing Gas from Supermassive Black Hole Nuclei
Supermassive black holes at the nuclei of most galaxies, including our Milky Way, develop gradually as material accretes onto the seed black hole. The physical…
Chandra Views Black Hole Bounty in the Center of the Milky Way
Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory….
What It Looks Like When A Massive Black Hole Devours A Star
Dr. Jane Lixin Dai, theoretical astrophysicist and assistant professor and Prof. Enrico Ramirez-Ruiz, both from the DARK Cosmology Center at the Niels Bohr Institute, University…
ExaHyPE – Simulation Code for New Generation of Supercomputers
Even after the direct measurement of their gravitational waves, there are still mysteries surrounding black holes. What happens when two black holes merge, or when…
Chandra Reveals X-Ray Binary Stars at the Galactic Center
The center of our Milky Way galaxy is about twenty-five thousand light years from Earth, in the direction of the constellation Sagittarius. At the core…
Webb Space Telescope Will Capture Light From First Generation Stars
The first stars in the universe blazed to life about 200 to 400 million years after the big bang. Observing those very first individual stars…
Milky Way’s Supermassive Black Hole May Have ‘Wandering’ Siblings
Astronomers are beginning to understand what happens when black holes get the urge to roam the Milky Way. Typically, a supermassive black hole (SMBH) exists…
Is Dark Matter Composed of Primordial Black Holes?
Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of…
Unprecedented ‘Dissection’ of Twin Galaxies in Final Stages of Merging
Researchers at the University of Colorado Boulder have completed an unprecedented “dissection” of twin galaxies in the final stages of merging. The new study, led…
Astrophysicists Test Theories of Gravity with Black Hole Shadows
Can we tell black holes apart? Astrophysicists at Goethe University Frankfurt answer this question by computing images of feeding non-Einsteinian black holes: At present it…
