SED Fitting of the Globular Clusters in Abell 2744 at z=0.3
Jinoo Kim, William E. Harris
We present a spectral energy distribution (SED) fitting analysis of globular cluster (GC) candidates in Abell 2744, a massive galaxy cluster at redshift z = 0.308 with a lookback t…
Massive Interacting Binaries Enhance Feedback in Star-Forming Regions
Claude Cournoyer-Cloutier, Eric P. Andersson, Sabrina M. Appel +9
We present a new framework to incorporate feedback from massive interacting binaries in simulations of star cluster formation. Our new feedback model adds binary stellar evolution…
Candidate Dark Galaxy-2: Validation and Analysis of an Almost Dark Galaxy in the Perseus Cluster
Dayi Li, Qing Liu, Gwendolyn Eadie +8
Candidate Dark Galaxy-2 (CDG-2) is a potential dark galaxy consisting of four globular clusters (GCs) in the Perseus cluster, first identified in Li et al. (2025) through a sophist…
Massive Star Cluster Formation with Binaries. I. Evolution of Binary Populations
Claude Cournoyer-Cloutier, Alison Sills, William E. Harris +7
We study the evolution of populations of binary stars within massive cluster-forming regions. We simulate the formation of young massive star clusters within giant molecular clouds…
Discovery of Two Ultra-Diffuse Galaxies with Unusually Bright Globular Cluster Luminosity Functions via a Mark-Dependently Thinned Point Process (MATHPOP)
Dayi Li, Gwendolyn Eadie, Patrick Brown +8
We present \textsc{Mathpop}, a novel method to infer the globular cluster (GC) counts in ultra-diffuse galaxies (UDGs) and low-surface brightness galaxies (LSBGs). Many known UDGs…
The Effect of Age and Stellar Model Choice on Globular Cluster Color-to-Metallicity Conversions
Kate Hartman, William E. Harris
The photometric colors of globular clusters (GCs) act as effective proxies for metallicity, since all normally used optical/IR color indices exhibit a nonlinear but monotonic relat…
Utilizing Voronoi Tessellations to Determine Radial Density Profiles
Veronika Dornan, William E. Harris
We have developed a novel method of determining 2D radial density profiles for astronomical systems of discrete objects using Voronoi tessellations. This Voronoi-based method was t…
Photometric Completeness Modelled With Neural Networks
William E. Harris, Joshua S. Speagle
In almost any study involving optical/NIR photometry, understanding the completeness of detection and recovery is an essential part of the work. The recovery fraction is, in genera…
Deep HST/UVIS imaging of the candidate dark galaxy CDG-1
Pieter van Dokkum, Dayi David Li, Roberto Abraham +4
CDG-1 is a tight grouping of four likely globular clusters in the Perseus cluster, and a candidate dark galaxy with little or no diffuse light. Here we provide new constraints on t…
Simulating the UV Escape Fractions from Molecular Cloud Populations in Star-forming Dwarf and Spiral Galaxies
Corey S. Howard, Ralph E. Pudritz, Bill E. Harris +1
The escape of ultraviolet photons from the densest regions of the interstellar medium (ISM) --- Giant Molecular Clouds (GMCs) --- is a poorly constrained parameter which is vital t…
Tracing the outer halo in a giant elliptical to 25 Reff
M. Rejkuba, W. E. Harris, L. Greggio +3
We have used the ACS and WFC3 cameras on board HST to resolve stars in the halo of the nearest giant elliptical (gE) galaxy NGC 5128 out to a projected distance of 140 kpc (25 effe…
Inclination-Independent Galaxy Classification
Jeremy Bailin, William E. Harris
We present a new method to classify galaxies from large surveys like the Sloan Digital Sky Survey using inclination-corrected concentration, inclination-corrected location on the c…
