The NuSTAR Extragalactic Surveys: Overview and Catalog from the COSMOS Field
F. Civano, R. C. Hickox, S. Puccetti +28
To provide the census of the sources contributing to the X-ray background peak above 10 keV, NuSTAR is performing extragalactic surveys using a three-tier "wedding cake" approach.…
A joint XMM-NuSTAR observation of the galaxy cluster Abell 523: constraints on Inverse Compton emission
F. Cova, F. Gastaldello, D. R. Wik +17
We present the results of a joint XMM-Newton and NuSTAR observation (200 ks) of the galaxy cluster Abell 523 at . The peculiar morphology of the cluster radio halo and its…
On the absence of radio halos in clusters with double relics
A. Bonafede, R. Cassano, M. Brüggen +10
Pairs of radio relics are believed to form during cluster mergers, and are best observed when the merger occurs in the plane of the sky. Mergers can also produce radio halos, throu…
Asymmetries in core-collapse supernovae from maps of radioactive Ti in CassiopeiaA
B. W. Grefenstette, F. A. Harrison, S. E. Boggs +28
Asymmetry is required by most numerical simulations of stellar core-collapse explosions, but the form it takes differs significantly among models. The spatial distribution of radio…
A NuSTAR observation of the center of the Coma Cluster
F. Gastaldello, D. R. Wik, S. Molendi +13
We present the results of a 55ks NuSTAR observation of the core of the Coma Cluster. The global spectrum can be explained by thermal gas emission, with a conservative 90% upper lim…
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…
