Constructing X-ray Spectral Models of Galaxies: Varying Contributions from X-ray Binary Populations with Host Galaxy Properties

Emerson Gehr, Bret D. Lehmer, Antara R. Basu-Zych +7

Recent work has shown that the emission from X-ray binary (XRB) populations in galaxies varies with stellar mass (), star formation rate (SFR), and metallicity (). Such…

The GlimmIr: Spectroscopic Variability in a z~7 LRD Indicates Rapid Changes in Both the Narrow and Broad Line Regions

Erini Lambrides, Taylor A. Hutchison, Rebecca L. Larson +39

The enigmatic population of ``Little Red Dots'' (LRDs) sit at the center of some of the largest debates in extragalactic astronomy today. The source(s) of ionizing emission and the…

Discovery of Multiply Ionized Iron Emission Powered by an Active Galactic Nucleus in a z~7 Little Red Dot

Erini Lambrides, Rebecca Larson, Taylor Hutchison +50

Some of the most puzzling discoveries of NASA's JWST in the early Universe surround the surprising abundance of compact red sources, which show peculiar continuum shapes and broad…

The Interstellar Medium in IZw18 seen with JWST/MIRI: I. Highly Ionized Gas

L. K. Hunt, A. Aloisi, M. G. Navarro +19

We present JWST/MIRI spectra from the Medium-Resolution Spectrometer of IZw18, a nearby dwarf galaxy with a metallicity of 3% Solar. Its proximity enables a detailed study of…

Emission Line Diagnostics for IMBHs in Dwarf Galaxies: Accounting for BH Seeding and ULX Excitation

Chris T. Richardson, Jordan Wels, Kristen Garofali +13

Dwarf AGN serve as the ideal systems for identifying intermediate mass black holes (IMBHs) down to the most elusive regimes (). However, the ubiquitousl…

Exploring the mysterious high-ionization source powering [Ne V] in high-z analog SBS0335-052 E with JWST/MIRI

Matilde Mingozzi, Macarena Garcia Del Valle-Espinosa, Bethan L. James +19

Nearby blue compact dwarf galaxies (BCDs) share similar properties with objects from the Epoch of Reionization revealed by JWST, in terms of low stellar mass, low metallicity and h…
