A Focused, Hard X-ray Look at Arp 299 with NuSTAR
A. Ptak, A. Hornschemeier, A. Zezas +19
We report on simultaneous observations of the local starburst system Arp 299 with NuSTAR and Chandra, which provides the first resolved images of this galaxy up to energies of ~ 45…
Spatially Resolving a Starburst Galaxy at Hard X-ray Energies: NuSTAR, Chandra, AND VLBA Observations of NGC 253
Daniel R. Wik, Bret D. Lehmer, Ann E. Hornschemeier +16
Prior to the launch of NuSTAR, it was not feasible to spatially resolve the hard (E > 10 keV) emission from galaxies beyond the Local Group. The combined NuSTAR dataset, comprised…
A new candidate Wolf-Rayet X-ray binary in NGC 253
Thomas J. Maccarone, Bret D. Lehmer, J. C. Leyder +5
We have discovered a persistent, but highly variable X-ray source in the nearby starburst galaxy NGC 253. The source varies at the level of a factor of about 5 in count rate on tim…
