The NuSTAR view of reflection and absorption in NGC 7582
E. Rivers, M. Baloković, P. Arévalo +14
NGC 7582 is a well-studied X-ray bright Seyfert 2 with moderately heavy (~cm), highly variable absorption and strong reflection spectral fea…
The hard X-ray emission of the luminous infrared galaxy NGC 6240 as observed by NuSTAR
S. Puccetti, A. Comastri, F. E. Bauer +23
We present a broad-band (~0.3-70 keV) spectral and temporal analysis of NuSTAR observations of the luminous infrared galaxy NGC 6240, combined with archival Chandra, XMM-Newton and…
NuSTAR Observations of the Compton-thick Active Galactic Nucleus and Ultraluminous X-ray Source Candidate in NGC 5643
A. Annuar, P. Gandhi, D. M. Alexander +22
We present two NuSTAR observations of the local Seyfert 2 active galactic nucleus (AGN) and an ultraluminous X-ray source (ULX) candidate in NGC 5643. Together with archival data f…
On the Nature of X-ray Surface Brightness Fluctuations in M87
P. Arévalo, E. Churazov, I. Zhuravleva +2
X-ray images of galaxy clusters and gas-rich elliptical galaxies show a wealth of small-scale features which reflect fluctuations in density and/or temperature of the intra-cluster…
The QUEST-La Silla AGN Variability Survey
Régis Cartier, Paulina Lira, Paolo Coppi +7
We present the characterization and initial results from the QUEST-La Silla AGN variability survey. This is an effort to obtain well sampled optical light curves in extragalactic f…
The NuSTAR X-ray spectrum of the low-luminosity AGN in NGC 7213
F. Ursini, A. Marinucci, G. Matt +11
We present an analysis of the 3-79 keV NuSTAR spectrum of the low-luminosity active galactic nucleus NGC 7213. In agreement with past observations, we find a lower limit to the hig…
