General Relativity at the April Meeting of the APS

2015 is the centennial of General Relativity. The April meeting of the APS in Baltimore, MD, will feature a concentration on general relativity and its impact in astrophysics and physics. There are many events and talks related to this topic.

Public Night at the Observatory! Features a presentation by a CRA astrophysicist!

The Georgia Tech Observatory is open to the public, and a CRA astrophysicist presents exciting recent research.

Join us on the rooftop of Howey, and view the Moon and other objects on the night sky.

HAWC erects tank 250
The High Altitude Water Cherenkov (HAWC) gamma-ray detector, of which Georgia Tech is a member has installed tank #250. HAWC operates by measuring ground level particles that are created when a very-high-energy gamma-ray strikes the upper atmosphere. Each of the HAWC tanks works as a "pixel" in 20,000 square meter camera. Building tank 250 meets the construction milestone set by the National Science Foundation and the Department of Energy. Construction will continue, past the milestone, to achieve the goal of 300 tanks. HAWC is already operating continuously (up time above 95%), with 111 tanks and has observed a dozen very high energy sources including the Crab nebula and active galactic nucleus Mrk 421.
NuSTAR Catches Black Holes on the Fly

NuSTAR, NASA's ground-breaking new hard X-ray observatory, reports the detection of the first 10 accreting supermassive black holes discovered by its `serendipitous' survey. By searching the images of all NuSTAR fields for active black holes lurking in the background, astrophysicists can gather information on the population of these objects in a relatively unbiased away. The vast majority of these first 10 objects are rapidly growing black holes in massive galaxies seen when the Universe was only about half its present age. CRA Professor David Ballantyne is a member of the NuSTAR science team and is actively working to understand the implications of NuSTAR's results on the history of black hole growth.

Wise and Collaborators Award Winning Visualizations

Dr. John Wise (Center for Relativistic Astrophysics and School of Physics), in conjunction with his collaborators, won the Best Visualization Prize in the XSEDE13 conference that showcases a diverse collection of computational driven sciences made possible by the NSF XSEDE computing resource. Their winning visualization depicts simulated data of the birth and death of the first stars in the universe and was made with the open-source analysis toolkit, yt.
