X-ray absorption variability in NGC 4507
Andrea Marinucci, Guido Risaliti, Junfeng Wang +5
We present a complete spectral analysis of an XMM-Newton and Chandra campaign of the obscured AGN in NGC 4507, consisting of six observations spanning a period of six months, rangi…
An Examination of the Spectral Variability in NGC 1365 with Suzaku
L. W. Brenneman, G. Risaliti, M. Elvis +1
We present jointly analyzed data from three deep Suzaku observations of NGC 1365. These high signal-to-noise spectra enable us to examine the nature of this variable, obscured AGN…
Decoupling absorption and continuum variability in the Seyfert 2 NGC 4507
V. Braito, L. Ballo, J. N. Reeves +3
We present the results of the Suzaku observation of the Seyfert 2 galaxy NGC 4507. This source is one of the X-ray brightest Compton-thin Seyfert 2s and a candidate for a variable…
Analysis of Spitzer-IRS spectra of hyperluminous infrared galaxies
A. Ruiz, G. Risaliti, E. Nardini +2
Hyperluminous infrared galaxies (HLIRG) are the most luminous persistent objects in the Universe. They exhibit extremely high star formation rates, and most of them seem to harbour…
The Chandra HRC View of the Sub-arcsecond Structures in the Nuclear Region of NGC 1068
Junfeng Wang, Giuseppina Fabbiano, Margarita Karovska +2
We have obtained a high spatial resolution X-ray image of the nucleus of NGC 1068 using the High Resolution Camera (HRC-I) on board the Chandra X-ray Observatory, which provides an…
The X-ray reflector in NGC 4945: a time and space resolved portrait
A. Marinucci, G. Risaliti, Junfeng Wang +5
We present a time, spectral and imaging analysis of the X-ray reflector in NGC 4945, which reveals its geometrical and physical structure with unprecedented detail. NGC 4945 hosts…
