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 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 کاملIron K and Compton hump reverberation in SWIFT J2127.4+5654 and NGC 1365 revealed by NuSTAR and XMM–Newton
In the past five years, a flurry of X-ray reverberation lag measurements of accreting supermassive black holes have been made using the XMM–Newton telescope in the 0.3–10 keV energy range. In this work, we use the NuSTAR (Nuclear Spectroscopic Telescope Array) telescope to extend the lag analysis up to higher energies for two Seyfert galaxies, SWIFT J2127.4+5654 and NGC 1365. X-ray reverberatio...
متن کاملDisclosing the true nature of the Sy 2 galaxy NGC 3281 : one more Compton - thick source
We present the BeppoSAX broad-band X–ray spectrum of the Seyfert 2 galaxy NGC 3281. The source high-energy spectrum is characterized by the nuclear transmitted component, with an absorbing column density of ≈ 2×10 cm, while the MECS spectrum is reflection-dominated, with a prominent (EW≈0.5–1.2 keV) iron Kα emission line. The source is detected at only the 5σ significance level in the LECS band...
متن کاملCold dust in the giant barred galaxy NGC 1365
Constraining the physcial properties of dust requires observations at submm wavelengths. This will provide important insight into the gas content of galaxies. We mapped NGC 1365 at 870 μm with LABOCA, the Large APEX Bolometer Camera, allowing us to probe the central mass concentration as well as the rate at which the gas flows to the center. We obtained the dust physical properties both globall...
