Spinning Black Holes, Exploding Stars, and Hyperluminous Pulsars: Recent Results from the NuSTAR Satellite

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, launched in June 2012 and became the first telescope in orbit to focus high energy X-ray light. This powerful X-ray emission provides a unique probe of the most energetic phenomena in the universe, from flares on the surface of the Sun, to the explosions of stars, to the extreme environments around neutron stars and black holes. The crisp, sensitive images enabled by NuSTAR's new technology have dramatically changed our picture of the extreme universe. This talk will present some of the highlights from the first four years of NuSTAR observations, including the surprising discovery of a new class of hyperluminous neutron stars, measurements of how fast black holes spin, and unique insight into the physics of supernova explosions.


Daniel K. Stern

Daniel Stern earned his AB in Physics at Princeton in 1991, and went on to earn his PhD in Astrophysics from UC Berkeley in 1999. He went straight from Berkeley to JPL, initially as a postdoc and later as a staff scientist. He has worked on multiple missions and mission concepts, including Spitzer, WISE, Euclid, WFIRST, a CubeSAT, a proposed X-ray polarimeter, the two future NASA flagship concepts for the 2030s, the Habitable Exoplanet Imaging Mission (HabEx) and an X-ray mission, Lynx. His main job currently is as the NuSTAR Project Scientist. Scientifically, Dr. Stern's main interests are observational cosmology and extragalactic astrophysics, but he's had a sideline finding the most distant objects of various source classes, including the most distant object, the most distant galaxy, the most distant radio galaxy, the most distant quasar, the most distant galaxy cluster and the most distant supernova. As one might expect, he's a very enthusiastic observer, having logged over 500 nights at telescopes worldwide over the past 20 years.


"What's Up?" in this month will be presented by Chris Butler
