We present a detailed X-ray spectral analysis of the nearby Seyfert 2 galaxy MCG-01-24-12 based on a multi-epoch data set. Data have been taken with different X-ray satellites, namely XMM-Newton, NuSTAR, Swift and Chandra and cover different time intervals, from years down to a few days. From 2006 to 2013 the source had a 2-10 keV flux of $sim$1.5$times$10$^{-11}$ erg cm$^{-2}$ s$^{-1}$, consistent with archival observations based on textit{HEAO} and textit{BeppoSAX} data, though a 2019 textit{Chandra} snapshot caught the source in an extreme low flux state, a factor of $sim$10 fainter than its historical one. Based on phenomenological and physically motivated models, we find the X-ray spectrum of MCG-01-24-12 to be best modelled by a power-law continuum emission with $Gamma$=1.76$pm$0.09 with a high energy cut-off at E$_{rm c}=70^{+21}_{-14}$ keV that is absorbed by a fairly constant column density of N$_{rm H}$=(6.3$pm$0.5)$times10^{22}$ cm$^{-2}$. These quantities allowed us to estimate the properties of the hot corona in MCG-01-24-12 for the cases of a spherical or slab-like hot Comptonising plasma to be kT$_{rm e}$=27$^{+8}_{-4}$ keV, $tau_{rm e}$=5.5$pm$1.3 and kT$_{rm e}$=28$^{+7}_{-5}$ keV, $tau$=3.2$pm$0.8, respectively. Finally, despite the short duration of the exposures, possible evidence of the presence of outflows is discussed.
We have carried out an extensive X-ray spectral study of the bare Seyfert-1 galaxy MCG--02--58--22 to ascertain the nature of the X-ray reprocessing media, using observations from Suzaku (2009) and simultaneous observations from XMM-Newton and NuSTAR
We report the results of a detailed analysis of a deep simultaneous $130,rm ks$ textit{XMM-Newton & NuSTAR} observation of the nearby ($z=0.0315$) and bright ($L_{rm bol}sim3times10^{45},rm erg,s^{-1}$) starburst-AGN Seyfert,2 system: MCG--03--58--00
Mkn 3 is a Seyfert 2 galaxy that is widely regarded as an exemplary Compton-thick AGN. We study the Suzaku X-ray spectrum using models of the X-ray reprocessor that self-consistently account for the Fe K$alpha$ fluorescent emission line and the assoc
We present the result of the Chandra high-resolution observation of the Seyfert~2 galaxy NGC 7590. This object was reported to show no X-ray absorption in the low-spatial resolution ASCA data. The XMM observations show that the X-ray emission of NGC
We present a flux-resolved X-ray analysis of the dwarf Seyfert 1.8 galaxy NGC 4395, based on three archival $XMM-Newton$ and one archival $NuSTAR$ observations. The source is known to harbor a low mass black hole ($sim 10^4- {rm a~ few~}times 10^{5}~
