X-Ray Echoes Demonstrate the Reality of Relativistic Reverberation
Limited by today’s telescope technology, an international team of astronomers looked for another way to probe supermassive black holes in distant galaxies. By analyzing data…
Gamma-Ray Beams Suggest Milky Way’s Central Black Hole Had Active Past
NASA’s Fermi space telescope captured evidence of two gamma-ray beams that extend from the galactic center to a distance of 27,000 light-years above and below…
Searching for the Link Between Star Formation and Black Hole Activity
To better understand the how star formation and black hole activity are linked, scientists are looking back 8 to 12 billion years, a time when…
Astronomers Observed Evolved Star Being Devoured
A team of CfA astronomers is reporting that the object they observed using the Pan-STARRS telescope was a supermassive black hole, roughly two million solar…
Black Hole Rips Apart a Helium Rich Star
Data captured by NASA’s Galaxy Evolution Explorer and the Pan-STARRS1 telescope show direct evidence of a supermassive black hole using its powerful gravitational forces to…
Astronomers Discover Large Group of Rogue Stars
As scientists are learning more about rogue stars, they are also learning new ways to locate them. A new study from astronomers at Vanderbilt University…
Extraordinary Outburst from Black Hole in Galaxy M83
Using NASA’s Chandra X-ray Observatory, scientists discovered a new ultraluminous X-ray source located in spiral galaxy M83, which is roughly 15 million light years from…
Black Holes Have an Appetite for Stars
It seems that black holes have appetites large enough to swallow stars. Astronomers at the University of Utah and the Harvard-Smithsonian Center for Astrophysics have…
The “Ordinary” Black Hole of Centaurus A
A newly published study describes the findings of a black hole located 12 million light years away in galaxy Centaurus A. Although black holes are…
Spacecraft to Explore Supermassive Black Holes at Center of Galaxies
By the standards of space-based astronomy, NASA’s new NuSTAR (Nuclear Spectroscopic Telescope Array) telescope that will be launched later this month has a modest budget…
“Zoom-Ins” Track and Model Parcels of Gas as They Move Inward Towards the Torus
Scientists aren’t sure how quasars form, how they develop in time, or how (or what) physical processes generate their stupendous energies; but by using a…
Thermonuclear Behavior of Neutron Star Bridges Gap Between Theory and Observation
Over the period of roughly one month, NASA’s Rossi X-ray Timing Explorer (RXTE) observed some 400 thermonuclear explosions on the surface of the neutron star…
Ultra-Fast Outflows are Common Features of Black-Hole-Powered Galaxies
Researchers targeted 42 nearby active galaxies and used data from the European Space Agency’s XMM-Newton satellite and NASA’s Rossi X-ray Timing Explorer satellite to show…
NASA’s Chandra Finds 20 Million MPH Wind
Researchers recently made two unanticipated findings when making observations from NASA’s Chandra X-ray Observatory. They clocked the fastest wind ever seen blowing off a disk…
Researchers Discover First Intermediate-Mass Black Hole
Using the Hubble Space Telescope, researchers have found an intermediate-mass black hole surrounded by a cluster of young, blue stars. This is the first finding…
Scientists Believe Milky Way’s Black Hole is Vaporizing Asteroids
Astronomers believe that the supermassive black hole known as Sagittarius A* located at the center of the Milky Way may be destroying a large number…
Relationship Between Black Hole Growth and Star Formation in Seyfert Galaxies
A new study in The Astrophysics Journal, which will be published on February 20th, shows that black hole growth is strongly correlated with nuclear star formation…
