The 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 کاملHighly ionized iron absorption lines from outflowing gas in the X - ray spectrum of NGC 1365
We present the discovery of four absorption lines in the X-ray spectrum of the Seyfert Galaxy NGC 1365, at energies between 6.7 and 8.3 keV. The lines are detected with high statistical confidence (from > 20σ for the strongest to ∼ 4σ for the weakest) in two XMM-Newton observations 60 ksec long. We also detect the same lines, with lower signal-to-noise (but still > 2σ for each line) in two prev...
متن کاملAGN / starburst connection in action : the half million second RGS spectrum of NGC 1365
Context. High-resolution X-ray observations in the imaging and spectral domain have recently opened a new window on active galactic nuclei (AGN) feedback onto the circumnuclear gas. Spectral diagnostics, as well as the remarkable morphological coincidence between [O iii] and X-rays, point to AGN photoionisation as the dominant ionisation mechanism on scales as large as a few kpc. Aims. In this ...
متن کاملA circumnuclear molecular torus in NGC 1365
The central region of NGC 1365 has been mapped in the J = 3 − 2 CO emission line with the 15 m SEST, which has a HPBW of 15′′ at the frequency of this transition. The observing grid has a 5′′-spacing in the inner and a 10′′-spacing in the outer region. A deconvolved map has been produced using the Maximum Entropy Method (MEM). A circumnuclear molecular torus with a radius of about 6. ′′5 is the...
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 ...
