Exploring Case B I: The Footprints of Hidden Radiation Fields in H I Balmer Decrements
Maryam Dehghanian, Fransisco Guzman, Peter van Hoof +2
Theory predicts that H I emission from photoionized clouds should lie close to the Case B limit established by Menzel and Baker, and observations of nearby nebulae have largely con…

Dissecting the Nuclear Structure of NGC 5548 with XRISM. I. Physical Properties of the Highly Ionized Outflows
Missagh Mehdipour, Jon M. Miller, Jelle S. Kaastra +21
We present a detailed spectral analysis of an X-Ray Imaging and Spectroscopy Mission (XRISM) observation of the prototypical Seyfert 1 galaxy NGC 5548. XRISM's Resolve microcalorim…

Comparing X-ray Emission Line Fluxes of NGC 5548 to NGC 1068
Divya Patel, Maryam Dehghanian, Gary Ferland
The Unification Model of AGN suggests that all AGN galaxies should exhibit similar line ratios in their spectra. NGC 5548, a Seyfert I, underwent obscuration -- similar to naturall…
