The Origin of X-ray Emission in the Gamma-ray emitting Narrow-Line Seyfert 1 1H 0323+342

Narrow-line Seyfert 1 (NLS1) galaxies are bright in the X-ray band and exhibit complex X-ray spectral features, such as an excess in soft X-ray emission and reflection features in the hard X-rays. In recent years, a new class of AGN with properties seen in both blazars and NLS1s, gamma-ray emitting NLS1s (gamma-NLS1s), has emerged, providing us with an unusual laboratory for studying the disk-corona-jet connection. The closest of these gamma-NLS1 galaxies is 1H 0323+342. Besides emitting in the gamma-rays, this AGN also shows superluminal motion in radio observations, implying that it has a jet oriented close to our line of sight. In this talk, I will present the results of X-ray spectral and timing analyses of 1H 0323+342, where we have used observations from a simultaneous XMM-Newton/NuSTAR campaign from 2018. Like other NLS1s, the spectrum reveals a soft excess at energies <2 keV and reflection features such as a broad iron K emission line. Using a combination of models that includes the razor-thin disk reflection model relxill to fit the broadband spectrum, we find a high disk inclination that is in tension with much lower values inferred by superluminal motion in the radio. In this presentation, I will explain these results by instead suggesting reflection off of a thick accretion disk geometry, and will show that 1H 0323+342 could be an adequate candidate for which to consider a geometrically thick flow.
