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…
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…
AGN activity and the misaligned hot ISM in the compact radio elliptical NGC4278
S. Pellegrini, J. Wang, G. Fabbiano +5
The analysis of a deep (579 ks) Chandra ACIS pointing of the elliptical galaxy NGC4278, which hosts a low luminosity AGN and compact radio emission, allowed us to detect extended e…
CHEERS results on Mrk 573: Study of deep Chandra observations
Alessandro Paggi, Junfeng Wang, Giuseppina Fabbiano +2
We present results on Mrk 573 obtained as part of the CHandra survey of Extended Emission-line Regions in nearby Seyfert galaxies (CHEERS). Previous studies showed that this source…
Probing the X-Ray Binary Populations of the Ring Galaxy NGC 1291
B. Luo, G. Fabbiano, T. Fragos +7
We present Chandra studies of the X-ray binary (XRB) populations in the bulge and ring regions of the ring galaxy NGC 1291. We detect 169 X-ray point sources in the galaxy, 75 in t…
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…
