We present an updated version of Lightning, a galaxy spectral energy distribution (SED) fitting code that can model X-ray to submillimeter observations. The models in Lightning inc…
The Impact of Inclination-dependent Attenuation on Ultraviolet Star Formation Rate Tracers
Keith Doore, Rafael T. Eufrasio, Bret D. Lehmer +3
We examine and quantify how hybrid (e.g., UV+IR) star formation rate (SFR) estimators and the - relation depend on inclination for disk-dominated galaxies using spe…
Elevated Hot Gas and High-Mass X-ray Binary Emission in Low Metallicity Galaxies: Implications for Nebular Ionization and Intergalactic Medium Heating in the Early Universe
Bret D. Lehmer, Rafael T. Eufrasio, Antara Basu-Zych +4
High-energy emission associated with star formation has been proposed as a significant source of interstellar medium (ISM) ionization in low-metallicity starbursts and an important…
On the Impact of Inclination-Dependent Attenuation on Derived Star Formation Histories: Results from Disk Galaxies in the Great Observatories Origins Deep Survey Fields
Keith Doore, Rafael T. Eufrasio, Bret D. Lehmer +4
We develop and implement an inclination-dependent attenuation prescription for spectral energy distribution (SED) fitting and study its impact on derived star-formation histories.…
On the Nature of AGN and Star Formation Enhancement in the SSA22 Protocluster: The HST WFC3 IR View
Erik B. Monson, Bret D. Lehmer, Keith Doore +9
We examine possible environmental sources of the enhanced star formation and active galactic nucleus (AGN) activity in the SSA22 protocluster using Hubble WFC3 F160W ($\…
Local Analogs to High-Redshift Galaxies: I. Characterization of Dust Emission and Star Formation History
Skarleth M Motiño Flores, Tommy Wiklind, Rafael T. Eufrasio
Star-forming dwarf galaxies have properties similar to those expected in high-redshift galaxies. Hence, these local galaxies may provide insights into the evolution of the first ga…
The Metallicity Dependence of the High-Mass X-ray Binary Luminosity Function
Bret D. Lehmer, Rafael T. Eufrasio, Antara Basu-Zych +7
We present detailed constraints on the metallicity dependence of the high mass X-ray binary (HMXB) X-ray luminosity function (XLF). We analyze ~5 Ms of Chandra data for 55 actively…
Evidence in favour of density wave theory through star formation history maps and spatially resolved stellar clusters
Shameer Abdeen, Daniel Kennefick, Julia Kennefick +7
Stationary Density Wave Theory predicts the existence of an age gradient across the spiral arms with a phase crossing at the co-rotation radius. Using star formation history (SFH)…
X-ray Binary Luminosity Function Scaling Relations in Elliptical Galaxies: Evidence for Globular Cluster Seeding of Low-Mass X-ray Binaries in Galactic Fields
