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.
Transient Gravitational Wave Sky
Interferometric detectors will very soon give us an unprecedented view of the gravitational-wave sky, and in particular of the explosive and transient Universe. Now is the time to challenge our theoretical understanding of short-duration gravitational-wave signatures from cataclysmic events, their connection to more traditional electromagnetic and particle astrophysics, and the data analysis techniques that will make the observations a reality. Check out the paper for the state of the art, future science opportunities, and current challenges in understanding gravitational-wave transients.
