Latest Gravitational wave Stories
An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale.The work is reported in a research article published today, Thursday, 16 July, in New Journal of Physics (co-owned by the Institute of Physics and German Physical Society). It can be found at...
U.S. physicists say they've determined the crusts of neutron stars are 10 billion times stronger than steel or any other metal alloy found on Earth. The scientists said a neutron star is a star that collapsed when its core ceased nuclear fusion. Exhibiting extreme gravity while rotating as fast as 700 times per second, a teaspoonful of neutron star matter would weight about 100 million tons, the researchers said. Indiana University Professor Charles Horowitz and colleagues conducted...
Research by a theoretical physicist at Indiana University shows that the crusts of neutron stars are 10 billion times stronger than steel or any other of the earth's strongest metal alloys. Charles Horowitz, a professor in the IU College of Arts and Sciences' Department of Physics, came to the conclusion after large-scale molecular dynamics computer simulations were conducted at Indiana University and Los Alamos National Laboratory in New Mexico. The research will appear Friday (May 8) in...
Cardiff University researchers who are part of a British-German team searching the depths of space to study gravitational waves, may have stumbled on 1 of the most important discoveries in physics according to an American physicistCardiff University researchers who are part of a British-German team searching the depths of space to study gravitational waves, may have stumbled on one of the most important discoveries in physics according to an American physicist.Craig Hogan, a physicist at...
In a move that would have any astrophysicist scratching his head, the U.S. Defense Intelligence Agency (DIA) commissioned a report to assess whether gravitational waves could threaten national security. The JASON Defense Advisory Group was also asked to investigate other potential applications for high-frequency gravitational waves, such as imaging the Earth's core or uses in telecommunications.Gravitational waves are wrinkles in space-time caused by the movement of objects with tremendously...
For decades it was baffling. Out of the still night sky, astronomers peering through their telescopes would occasionally glimpse quick bursts of high-energy light popping off like flashbulbs at the far side of the universe.These bursts seemed impossibly powerful: to appear so bright from so very far away, they must vastly outshine entire galaxies containing hundreds of billions of stars. These explosions, called gamma ray bursts (GRBs), are by far the brightest and most energetic phenomena in...
By Kevin Sieff, The Brownsville Herald, Texas Jun. 17--Ten years ago, the University of Texas at Brownsville and Texas Southmost College lacked even a basic physics department. Now, the university's Center for Gravitational Wave Astronomy is world renowned, its students and professors at the cutting edge of international research. In the most recent of the program's accolades, four UTB-TSC physics professors have been selected to teach Chinese scientists and graduate students about their...
ESA's orbiting gamma-ray observatory, Integral has revealed a new population of exotic and dusty binary stars which might represent a brief evolutionary period in a binary star's life. The findings bring to light a gap in our knowledge of the formation and evolution of such binary star systems. Since 2002, when Integral was launched, the observatory has been surveying the galaxy, looking for sources of the most powerful X-rays and gamma rays. Fifteen of its new discoveries appeared to be...
New information about the heart of one of the most famous objects in the sky -- the Crab Pulsar in the Crab Nebula -- has been revealed by an international team of scientists searching for gravitational waves. The team's achievement also is the first direct look into the interior of a neutron star.The research team detected signals from the pulsar -- a rapidly spinning neutron star -- with the Laser Interferometer Gravitational-Wave Observatory (LIGO). The analysis of the signals reveals that...
Aim to produce new generation of astronomer that understands theory and observationThe future of fundamental physics research lies in observing the early universe and developing models that explain the new data obtained. The availability of much higher resolution data from closer to the start of the universe is creating the potential for further significant theoretical breakthroughs and progress resolving some of the most difficult and intractable questions in physics. But this requires much...
