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…
Deep observations of the NGC 4472 globular cluster black hole XMMU 122939.7+075333: Short term variability from the first globular cluster black hole binary
Tana D. Joseph, Thomas J. Maccarone, Ralph P. Kraft +1
In this paper we discuss the luminosity modulations and spectral analysis results of the recent deep observations of XMMU 122939.7+075333, the first black hole discovered in a glob…
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…
An Ultraluminous X-ray Source Powered by An Accreting Neutron Star
M. Bachetti, F. A. Harrison, D. J. Walton +21
Ultraluminous X-ray sources (ULX) are off-nuclear point sources in nearby galaxies whose X-ray luminosity exceeds the theoretical maximum for spherical infall (the Eddington limit)…
No Time for Dead Time: Timing analysis of bright black hole binaries with NuSTAR
Matteo Bachetti, Fiona A. Harrison, Rick Cook +20
Timing of high-count rate sources with the NuSTAR Small Explorer Mission requires specialized analysis techniques. NuSTAR was primarily designed for spectroscopic observations of s…
Reversibility of time series: revealing the hidden messages in X-ray binaries and cataclysmic variables
S. Scaringi, T. J. Maccarone, M. Middleton
We explore the non-linear, high-frequency, aperiodic variability properties in the three cataclysmic variables MV Lyr, KIC 8751494 and V1504 Cyg observed with Kepler, as well as th…
