Discovery of a giant radio fossil in the Ophiuchus galaxy cluster
S. Giacintucci, M. Markevitch, M. Johnston-Hollitt +3
The Ophiuchus galaxy cluster exhibits a curious concave gas density discontinuity at the edge of its cool core. It was discovered in the Chandra X-ray image by Werner and collabora…
Black Holes and Neutron Stars in Nearby Galaxies: Insights from NuSTAR
Neven Vulic, Ann E. Hornschemeier, Daniel R. Wik +8
Nearby galaxy surveys have long classified X-ray binaries (XRBs) by the mass category of their donor stars (high-mass and low-mass). The NuSTAR observatory, which provides imaging…
Identification of the Hard X-ray Source Dominating the E > 25 keV Emission of the Nearby Galaxy M31
M. Yukita, A. Ptak, A. E. Hornschemeier +15
We report the identification of a bright hard X-ray source dominating the M31 bulge above 25 keV from a simultaneous NuSTAR-Swift observation. We find that this source is the count…
A Hard X-ray Study of the Normal Star-Forming Galaxy M83 with NuSTAR
M. Yukita, A. E. Hornschemeier, B. D. Lehmer +19
We present results from sensitive, multi-epoch NuSTAR observations of the late-type star-forming galaxy M83 (d=4.6 Mpc), which is the first investigation to spatially resolve the h…
The 0.3-30 keV Spectra of Powerful Starburst Galaxies: NuSTAR and Chandra Observations of NGC 3256 and NGC 3310
B. D. Lehmer, J. B. Tyler, A. E. Hornschemeier +13
We present nearly simultaneous Chandra and NuSTAR observations of two actively star-forming galaxies within 50 Mpc: NGC 3256 and NGC 3310. Both galaxies are detected by both Chandr…
