The hard X-ray spectrum of NGC 5506 as seen by NuSTAR
G. Matt, M. Balokovic, A. Marinucci +12
NuSTAR observed the bright Compton-thin, narrow line Seyfert 1 galaxy, NGC 5506, for about 56 ks. In agreement with past observations, the spectrum is well fit by a power law with…
ASTRO-H White Paper - Broad-band Spectroscopy and Polarimetry
P. Coppi, L. Stawarz, C. Done +13
The broad energy range spanned by ASTRO-H instruments, from ~0.3 to 600 keV, with its high spectral resolution calorimeter and sensitive hard X-ray imaging, offers unique opportuni…
ASTRO-H White Paper - Clusters of Galaxies and Related Science
T. Kitayama, M. Bautz, M. Markevitch +22
The next generation X-ray observatory ASTRO-H will open up a new dimension in the study of galaxy clusters by achieving for the first time the spectral resolution required to measu…
Gamma-ray flaring activity from the gravitationally lensed blazar PKS 1830-211 observed by Fermi LAT
The Fermi LAT Collaboration, A. A. Abdo, M. Ackermann +126
The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope routinely detects the highly dust-absorbed, reddened, and MeV-peaked flat spectrum radio quasar PKS 1830…
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 spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV
The Fermi LAT collaboration, M. Ackermann, M. Ajello +142
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a res…
The NuSTAR View of Nearby Compton-thick AGN: The Cases of NGC 424, NGC 1320 and IC 2560
M. Baloković, A. Comastri, F. A. Harrison +25
We present X-ray spectral analyses for three Seyfert 2 active galactic nuclei, NGC 424, NGC 1320, and IC 2560, observed by NuSTAR in the 3-79 keV band. The high quality hard X-ray…
NuSTAR unveils a Compton-thick Type 2 quasar in Mrk 34
P. Gandhi, G. B. Lansbury, D. M. Alexander +27
We present Nustar 3-40 keV observations of the optically selected Type 2 quasar (QSO2) SDSS J1034+6001 or Mrk 34. The high-quality hard X-ray spectrum and archival XMM-Newton data…
The 2-79 keV X-ray Spectrum of the Circinus Galaxy with NuSTAR, XMM-Newton and Chandra: a Fully Compton-Thick AGN
P. Arévalo, F. E. Bauer, S. Puccetti +24
The Circinus galaxy is one of the nearest obscured AGN, making it an ideal target for detailed study. Combining archival Chandra and XMM-Newton data with new NuSTAR observations, w…
The Broad-band X-ray Spectrum of IC 4329A from a Joint NuSTAR/Suzaku Observation
Laura Brenneman, G. Madejski, F. Fuerst +16
We have obtained a deep, simultaneous observation of the bright, nearby Seyfert galaxy IC 4329A with Suzaku and NuSTAR. Through a detailed spectral analysis, we are able to robustl…
NuSTAR Observations of the Bullet Cluster: Constraints on Inverse Compton Emission
Daniel R. Wik, Allan Hornstrup, Silvano Molendi +16
The search for diffuse non-thermal inverse Compton (IC) emission from galaxy clusters at hard X-ray energies has been undertaken with many instruments, with most detections being e…
