Chandra Reveals Heavy Obscuration and Circumnuclear Star Formation in Seyfert 2 Galaxy NGC 4968
Stephanie M. LaMassa, Tahir Yaqoob, N. A. Levenson +6
We present the Chandra imaging and spectral analysis of NGC 4968, a nearby (z = 0.00986) Seyfert 2 galaxy. We discover extended (1 kpc) X-ray emission in the soft band (0.5 -…
First NuSTAR observations of the BL Lac - type blazar PKS~2155-304: constraints on the jet content and distribution of radiating particles
G. M. Madejski, K. Nalewajko, K. K. Madsen +35
We report the first hard X-ray observations with NuSTAR of the BL Lac type blazar PKS 2155-304, augmented with soft X-ray data from XMM-Newton and gamma-ray data from the Fermi Lar…
A New Population of Compton-Thick AGN Identified Using the Spectral Curvature Above 10 keV
Michael J. Koss, R. Assef, M. Balokovic +18
We present a new metric that uses the spectral curvature (SC) above 10 keV to identify Compton-thick AGN in low-quality Swift BAT X-ray data. Using NuSTAR, we observe nine high SC-…
Peering through the Dust: NuSTAR Observations of Two FIRST-2MASS Red Quasars
Stephanie M. LaMassa, Angelo Ricarte, Eilat Glikman +17
Some reddened quasars appear to be transitional objects in the merger-induced black hole growth/galaxy evolution paradigm, where a heavily obscured nucleus starts to be unveiled by…
