The Goldilocks Molecule: H Emission Lines Can Identify Elusive Dwarf AGN
Morgan Micharski, Chris Richardson
We propose using H emission lines as a novel diagnostic to identify dwarf AGN by running photoionization models incorporating active intermediate-mass black holes and using a…
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…
Modeling the molecular gas content and CO-to-H2 conversion factors in low-metallicity star-forming dwarf galaxies
L. Ramambason, V. Lebouteiller, S. C. Madden +8
Low-metallicity dwarf galaxies often show no or little CO emission, despite the intense star formation observed in local samples. Both simulations and resolved observations indicat…
RESOLVE and ECO: Finding Low-Metallicity Dwarf AGN Candidates Using Optimized Emission-Line Diagnostics
Mugdha S. Polimera, Sheila J. Kannappan, Chris T. Richardson +6
Existing star-forming vs. active galactic nucleus (AGN) classification schemes using optical emission-line diagnostics mostly fail for low-metallicity and/or highly star-forming ga…
Optical and JWST Mid-IR Emission Line Diagnostics for Simultaneous IMBH and Stellar Excitation in z~0 Dwarf Galaxies
C. T. Richardson, C. Simpson, M. S. Polimera +4
Current observational facilities have yet to conclusively detect intermediate mass black holes (IMBHs) that fill in the evolutionary gap between early unive…
Addressing the [O III]/H\b{eta} Offset of Dwarf Galaxies in the RESOLVE Survey
Chris T. Richardson, Mugdha S. Polimera, Sheila J. Kannappan +2
Metal poor dwarf galaxies in the local universe, such as those found in the RESOLVE galaxy survey, often produce high [O III]/H\b{eta} ratios close to the star forming demarcation…
