dc.description.abstract | 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 were obtained with different X-ray satellites, namely XMM-Newton, NuSTAR, Swift, and Chandra, and cover different time intervals, from a few days to years. From 2006 to 2013 the source had a 2-10 keV flux of ∼1.5 × 10<SUP>−11</SUP> erg cm<SUP>−2</SUP> s<SUP>−1</SUP>, consistent with archival observations based on HEAO and BeppoSAX data, though a 2019 Chandra snapshot caught the source in an extreme low flux state a factor of ∼10 fainter than its historical level. 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 Γ = 1.76 ± 0.09 with a high energy cut-off at E<SUB>c</SUB> = 70<SUB>−14</SUB><SUP>+21</SUP> keV that is absorbed by a fairly constant column density of N<SUB>H</SUB> = (6.3 ± 0.5) × 10<SUP>22</SUP> cm<SUP>−2</SUP>. 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<SUB>e</SUB> = 27<SUB>−4</SUB><SUP>+8</SUP> keV, τ<SUB>e</SUB> = 5.5 ± 1.3 and kT<SUB>e</SUB> = 28<SUB>−5</SUB><SUP>+7</SUP> keV, τ = 3.2 ± 0.8, respectively. Finally, despite the short duration of the exposures, possible evidence of the presence of outflows is discussed. | en_US |
