Fast and Furious: Shock Heated Gas as the Origin of Spatially Resolved Hard X-ray Emission in the Central 5 kpc of the Galaxy Merger NGC 6240
Junfeng Wang, Emanuele Nardini, Giuseppina Fabbiano +7
We have obtained a deep, sub-arcsecond resolution X-ray image of the nuclear region of the luminous galaxy merger NGC 6240 with Chandra, which resolves the X-ray emission from the…
The Exceptional Soft X-ray Halo of the Galaxy Merger NGC 6240
Emanuele Nardini, Junfeng Wang, Giuseppina Fabbiano +5
We report on a recent ~150-ks long Chandra observation of the ultraluminous infrared galaxy merger NGC 6240, which allows a detailed investigation of the diffuse galactic halo. Ext…
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…
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…
A Close Nuclear Black Hole Pair in the Spiral Galaxy NGC 3393
G. Fabbiano, Wang Junfeng, M. Elvis +1
The current picture of galaxy evolution advocates co-evolution of galaxies and their nuclear massive black holes (MBHs), through accretion and merging. Quasar pairs (6,000-300,000…
