A new, Yale-led study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies — and the supermassive black holes within their cores — aggregate into clusters, these clusters create a volatile, highly pressurized environment. Individual galaxies falling into […]

Hot spots circling around the black hole could produce the quasi-periodic millimeter emission detected with ALMA. Credit: Keio University Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due to […]

Two orbiting black holes. Credit: Josh Valenzuela/UNM A team of researchers from the ARC Centre of Excellence for Gravitational Wave discovery (OzGrav) recently published a study revealing something unexpected about black holes: that intermediate-mass black holes with precessing orbits should be easier to detect than standard ones.​ Black holes are […]

The Russian RATAN-600 telescope helps to understand the origin of cosmic neutrinos. Credit: Daria Sokol/MIPT Press Office Russian researchers trace high-energy neutrino origins to black holes in far-off quasars. Russian astrophysicists have come close to solving the mystery of where high-energy neutrinos come from in space. The team compared the […]

A composite view of the Abell 2384 system, comprising two galaxy clusters located 1.2 billion light years from Earth. A new study, based on data from ESA’s XMM-Newton and NASA’s Chandra X-ray observatories, sheds new light on a three million light-year long bridge of hot gas linking two galaxy clusters, whose […]

Artist illustration of two black holes orbiting each other. Credit: NASA/CXC/A.Hobart Scientists from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) reveal an alternative explanation of the recently announce black hole merger. The paper was just accepted by Astrophysical Journal Letters. On the 12th of April 2019, the LIGO and Virgo observatories detected gravitational […]

NASA’s Spitzer Space Telescope may be retired, but the things it witnessed during its sixteen and a half year mission will be the subject of study for many years to come. For instance, Spitzer is the only telescope to witness something truly astounding occurring at the center of the distant galaxy OJ 287: a supermassive […]
