Scientists at Low Temperature Laboratory planning to model a black hole
Academy Professor Matti Krusius and Antti Finne, M.Sc. (Eng.), were invited to a recent science breakfast, hosted by the Academy of Finland, to talk about their ongoing work to produce a first-ever laboratory simulation of a black hole. A black hole is created as a result of the most extreme concentration of matter. Scientists have been arguing... view more... (2003-04-16)
The accretion disks around super-massive black holes: do they really exist?
Active Galactic Nuclei (AGN) and quasars (QSO) are the most luminous objects in the sky. These are powered by accretion of interstellar gas onto a supermassive black hole (BH) of about 100 millions solar masses which stands at the center of galaxies. For Seyfert galaxies, a few tenths of solar masses of gas per year is required to fuel the black... view more... (2001-04-17)
Hubble sees magnetic monster in erupting galaxy
The Hubble Space Telescope has found the answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example of the influence of these immense tentacles of extragalactic magnetic fields, say researchers. view more (2008-08-21)
Monster black holes grow after galactic mergers
An analysis of the Hubble Space Telescope's deepest view of the universe offers compelling evidence that monster black holes in the centers of galaxies were not born big but grew over time through repeated galactic mergers. view more (2006-01-11)
RIT Team Simulates First Merger of Three Black Holes on a Supercomputer
The same team of astrophysicists that cracked the computer code simulating two black holes crashing and merging together has now, for the first time, caused a three-black-hole collision. view more (2008-04-09)
Chandra catches 'piranha' black holes
Supermassive black holes have been discovered to grow more rapidly in young galaxy clusters, according to new results from NASA's Chandra X-ray Observatory. view more (2007-07-25)
First Black Holes Born Starving
The first black holes in the universe had dramatic effects on their surroundings despite the fact that they were small and grew very slowly, according to recent supercomputer simulations carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of... view more...

Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust. view more (2005-08-08)
Black hole found in enigmatic Omega Centauri
A new discovery has resolved some of the mystery surrounding Omega Centauri, the largest and brightest globular cluster in the sky. Images obtained with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope and data obtained by the GMOS spectrograph on the Gemini South telescope in Chile show that Omega Centauri appears to... view more...

Study: Perception of hole size influenced by performance
Golfers who play well are more likely to see the hole as larger than their poor-playing counterparts, according to a Purdue University researcher. view more (2008-07-08)
Neutron stars join the black hole jet set
NASA's Chandra X-ray Observatory has revealed an X-ray jet blasting away from a neutron star in a binary system. view more (2007-06-28)
Physicists and engineers search for new dimension
The universe as we currently know it is made up of three dimensions of space and one of time, but researchers in the Department of Physics and the Department of Electrical and Computer Engineering at Virginia Tech are exploring the possibility of an extra dimension. view more (2008-03-11)
High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four... view more...

Closest Look Ever at the Edge of a Black Hole
Astronomers have taken the closest look ever at the giant black hole in the center of the Milky Way. By combining telescopes in Hawaii, Arizona, and California, they detected structure at a tiny angular scale of 37 micro-arcseconds - the equivalent of a baseball seen on the surface of the moon, 240,000 miles distant. view more (2008-09-04)
New panorama reveals more than a thousand black holes
By casting a wide net, astronomers have captured an image of more than a thousand supermassive black holes. These results give astronomers a snapshot of a crucial period when these monster black holes are growing, and provide insight into the environments in which they occur. view more (2007-03-13)
`Quiet` star wasn`t quiet after all, say astronomers
For more than two years the star was `quiet`. Or so astronomers thought. But the X-ray pulsar EXO 2030+375 was abuzz with activity. Scientists simply lacked the ability to `hear` it over the hum of a nearby black hole. Now a study by scientists at the University of Southampton, the National Space Science and Technology Center (NSSTC) in... view more... (2002-07-10)
Black hole in search of a home
The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars. view more (2005-09-15)
Cosmic battle creates Milky-Way sized tunnel
A team of astronomers is announcing today that they have discovered a giant Milky Way-sized tunnel filled with high energy particles in a distant galaxy cluster. view more (2006-01-12)
Astronomers report unprecedented double helix nebula near center of the Milky Way
Astronomers report an unprecedented elongated double helix nebula near the center of our Milky Way galaxy, using observations from NASA's Spitzer Space Telescope. view more (2006-03-16)
RIT Study Confirms Supermassive Black Holes Produce Powerful Galaxy-Shaping Winds
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists from Rochester Institute of Technology. view more (2007-11-01)
