X - ray observations of NGC 1365 : time - resolved eclipse of the X - ray source
نویسنده
چکیده
We present an extraordinary variation of the X-ray spectrum of the obscured AGN in NGC 1365, which was observed by Chandra to change from Compton-thin to Compton-thick and back to Compton-thin in four days. This fast variation imply a a size of ∼ 10 14 cm for the emitting region, and an extremely compact size (∼ 10 16 cm) of the clumpy circumnuclear absorber.

High Resolution X-ray Imaging Observations of Two Low Luminosity Seyfert Galaxies
Results from observations of two nearby, low X-ray luminosity Seyfert-type galaxies, namely, NGC 1365, and NGC 4051, using the ROSAT High Resolution Imager (HRI) are presented. The observations carried out with the aim of detecting and resolving the extra-nuclear (beyond the central 5–10) X-ray emission show evidence for an extended component of ≃2 kpc size in NGC 1365 and NGC 4051. The extende...
متن کاملImaging the Circumnuclear Region of NGC 1365 with Chandra
We present the first Chandra/ACIS imaging study of the circumnuclear region of the nearby Seyfert galaxy NGC 1365. The X-ray emission is resolved into point-like sources and complex, extended emission. The X-ray morphology of the extended emission shows a biconical soft X-ray emission region extending ∼5 kpc in projection from the nucleus, coincident with the high excitation outflow cones seen ...
متن کاملThe XMM - Newton long look of NGC 1365 : uncovering of the obscured X - ray source
We present an analysis of the extreme obscuration variability observed during an XMM-Newton 5-days continuous monitoring of the AGN in NGC 1365. The source was in a reflection-dominated state in the first ∼ 1.5 days, then a strong increase of the 7-10 keV emission was observed in ∼10 hours, followed by a symmetric decrease. The spectral analysis of the different states clearly shows that this v...
متن کاملThe ROSAT view of NGC 1365 and the luminous highly variable off-nuclear X-ray source NGC 1365–X1
We present an X-ray spectral and spatial analysis of the composite starburst/Seyfert galaxy NGC1365. Excellent fits of the ROSAT PSPC spectrum are obtained by combining a soft thermal component with a hard powerlaw. The hard component may be either seen directly or can be explained by scattering of the AGN powerlaw at circumnuclear warm high-column-density gas. A compilation of the multi-wavele...
متن کاملNuSTAR OBSERVATIONS OF THE COMPTON-THICK ACTIVE GALACTIC NUCLEUS AND ULTRALUMINOUS X-RAY SOURCE CANDIDATE IN NGC 5643
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 from Chandra, XMM-Newton and Swift-BAT, we perform a high-quality broadband spectral analysis of the AGN over two decades in energy (∼0.5–100 keV). Previous X-ray observations suggested that the AGN is obscured by a Co...
