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…

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…

Recovering the properties of the interstellar medium through integrated spectroscopy: application to the z~0 ECO volume-limited star-forming galaxy sample

V. Lebouteiller, C. T. Richardson, M. S. Polimera +7

Deriving physical parameters from integrated galaxy spectra is paramount to interpret the cosmic evolution of star formation, chemical enrichment, and energetic sources. We develop…

Probing the heating of the neutral atomic interstellar medium in the Dwarf Galaxy Survey through infrared cooling lines

Maxime Varese, Vianney Lebouteiller, Lise Ramambason +3

Star formation in galaxies is regulated by dynamical and thermal processes. The photoelectric effect on small dust grains usually dominates the heating of the star-forming neutral…
