Scientists use simulations to investigate what kind of "flash" might be seen by telescopes when astronomers ultimately find gravitational signals from merging black holes.
A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs).
A European team working on the LISA Pathfinder mission has completed an extensive series of ground tests on the spacecraft's optical payload. The tests successfully achieved - for the first time on a spacecraft instrument - the incredible precision that will be required to confirm the existence of gravitational waves.
NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar cinders work.
Dr Alice Harding has been awarded the
American Astronomical Society High Energy Astrophysics Division Rossi Prize.
The award is made jointly to Alice and Dr Roger Romani from Stanford
University. The citation reads "To Alice K Harding and Roger W. Romani for
establishing a theoretical framework for understanding gamma-ray pulsars."
Congratulations to new APS Fellow
11.26.2012
Please congratulate Dr. Demos Kazanas for his election to Fellow of the American Physical Society (APS). The
citation reads "For diverse contributions to Astrophysics, ranging from a
1980 independent resolution, of the cosmological horizon problem using the
vacuum energy of spontaneously broken gauge theory -- to the recent idea
that AGN appearance depends on the properties of MHD winds launched from
their accretion disks."
The Gravitational Astrophysics Laboratory conducts a broad range of scientific investigations to test Einstein's theory of General Relativity. The Laboratory provides the science and technical leadership to develop space-based gravitational wave detection systems. Research encompasses a variety of areas, including numerical relativity, LISA mission sources and data analysis, integrated modeling, theoretical modeling of high-energy astrophysics sources, and interferometry.
