TL;DR
This paper provides a comprehensive X-ray spectral analysis of Seyfert 2 galaxy MCG-01-24-12 across multiple epochs and instruments, revealing its spectral properties, variability, and potential outflows.
Contribution
It offers the first detailed multi-epoch X-ray spectral modeling of MCG-01-24-12, including estimates of coronal properties and evidence of outflows.
Findings
Consistent 2-10 keV flux from 2006-2013 with a significant low state in 2019.
Power-law photon index of 1.76 and high energy cut-off at 70 keV.
Estimated coronal temperature around 27-28 keV and optical depth of 3.2-5.5.
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 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 1.510 erg cm s, 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 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 =1.760.09 with a high energy cut-off at E keV that is absorbed by a fairly…
