Survey of Bare Active Galactic Nuclei in the local universe (z < 0.2): I. On the origin of Soft-Excess
We analyse a sample of 21 `bare' Seyfert~1 Active Galactic Nuclei (AGNs), a sub-class of Seyfert~1s, with intrinsic absorption $\mathrm{N_{H}} \sim 10^{20}~ \mathrm{cm}^{-2}$, in the local universe (z $

XMM-Newton} and {\it Swift}/XRT observations. The luminosities of the primary
continuum, the X-ray emission in the 3 to 10 keV energy range and the
soft-excess, the excess emission that appears above the low-energy
extrapolation of the power-law fit of 3 to 10 keV X-ray spectra, are
calculated. Our spectral analysis reveals that the long-term intrinsic
luminosities of the soft-excess and the primary continuum are tightly
correlated $(L_{PC}\propto L_{SE}^{1.1\pm0.04})$. We also found that the
luminosities are correlated for each source. This result suggests that both the
primary continuum and soft excess emissions exhibit a dependency on the
accretion rate in a similar way.</description><identifier>DOI: 10.48550/arxiv.2308.08528</identifier><language>eng</language><subject>Physics - Astrophysics of Galaxies ; Physics - High Energy Astrophysical Phenomena</subject><creationdate>2023-08</creationdate><rights>http://creativecommons.org/licenses/by/4.0</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>228,230,780,885</link.rule.ids><linktorsrc>$$Uhttps://arxiv.org/abs/2308.08528$$EView_record_in_Cornell_University$$FView_record_in_$$GCornell_University$$Hfree_for_read</linktorsrc><backlink>$$Uhttps://doi.org/10.48550/arXiv.2308.08528$$DView paper in arXiv$$Hfree_for_read</backlink></links><search><creatorcontrib>Nandi, Prantik</creatorcontrib><creatorcontrib>Chatterjee, Arka</creatorcontrib><creatorcontrib>Jana, Arghajit</creatorcontrib><creatorcontrib>Chakrabarti, Sandip K</creatorcontrib><creatorcontrib>Naik, Sachindra</creatorcontrib><creatorcontrib>Safi-Harb, Samar</creatorcontrib><creatorcontrib>Chang, Hsiang-Kuang</creatorcontrib><creatorcontrib>Heyl, Jeremy</creatorcontrib><title>Survey of Bare Active Galactic Nuclei in the local universe (z < 0.2): I.
