On the Fe xxii Emission in the X-ray spectrum of NGC 1068
M. Z. Buhariwalla, J. M. Miller, L. C. Gallo +3
The Fe xxii doublet has been previously used to determine the density of collisionally ionized emission from magnetic cataclysmic variable stars. We test how this diagnostic double…
XRISM Spectroscopy of Accretion-Driven Wind Feedback in NGC 4151
Xin Xiang, Jon M. Miller, Ehud Behar +17
The hottest, most ionized, and fastest winds driven by accretion onto massive black holes have the potential to reshape their host galaxies. Calorimeter-resolution X-ray spectrosco…
A Spectral Energy Distribution Variability Study of the Eclipsing AGN NGC 6814
L. K. Pothier-Bogoslowski, L. C. Gallo, A. G. Gonzalez +2
The local Seyfert 1.5 active galactic nucleus (AGN), NGC 6814, is known to exhibit complex variability, eclipses, and even changing-look behaviour. In this work, we utilize optical…
A Hot Mess: The Rich and Complex Soft Emitting Regions Surrounding the Reflection Dominated Flaring Central Engine of Mrk 1239
Margaret Z. Buhariwalla, L. C. Gallo, J. Mao +5
Previous X-ray works on Mrk 1239 have revealed a complex Narrow Line Seyfert 1 (NLS1) that exhibits substantial absorption and strong emission from both collisional (CIE) and photo…
The Collisional and Photoionized Plasma in the Polarized NLS1 galaxy Mrk 1239
Margaret Z. Buhariwalla, Luigi C. Gallo, J. Mao +4
Mrk 1239 is a highly polarized NLS1 in the optical band, whose keV spectrum has remained remarkably consistent over more than two decades of observation. Previous analysis…
A truncated inner disc in the Seyfert 1 galaxy WKK 4438
L. C. Gallo, M. Z. Buhariwalla, J. Jiang +2
Understanding if and when the accretion disc extends down to the innermost stable circular orbit (ISCO) is important since it is the fundamental assumption behind measuring black h…
Uncovering the primary X-ray emission and possible starburst component in the polarized NLS1 Mrk 1239
Margaret Z. Buhariwalla, Sophia G. H. Waddell, Luigi C. Gallo +2
X-ray observations of the unique NLS1 galaxy Mrk 1239 spanning 18-years are presented. Data from XMM-Newton, Suzaku, Swift and NuSTAR are combined to obtain a broad-band, multi-epo…
