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…
Deep X-ray observation of NGC 3221: everything everywhere all at once
Sanskriti Das, Smita Mathur, Bret D. Lehmer +3
We present a comprehensive analysis of 475 ks (438 ks unpublished & 37 ks archival) XMM-Newton/EPIC-pn observation of a nearby, highly inclined, star-forming, luminous infrared gal…
XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy
Peter G. Boorman, Jiří Svoboda, Daniel Stern +23
Green Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local universe. They are believed to be analogues of high-redshift gala…
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…
Fast SMBH growth in the SPT2349--56 protocluster at
Fabio Vito, William N. Brandt, Andrea Comastri +7
Protoclusters at are gas-rich regions characterized by high star-formation activity. The same physical properties that enhance star formation in protoclusters are also though…
Modeling the High-Energy Ionizing Output from Simple Stellar and X-ray Binary Populations
Kristen Garofali, Antara R. Basu-Zych, Benjamin D. Johnson +9
We present a methodology for modeling the joint ionizing impact due to a "simple X-ray population" (SXP) and its corresponding simple stellar population (SSP), where "simple" refer…
