Mapping Gamma-Ray Bursts: Distinguishing Progenitor Systems Through Machine Learning
Sharleen N. Espinoza, Nicole M. Lloyd-Ronning, Michela Negro +2
We present an analysis of gamma-ray burst (GRB) progenitor classification, through their positions on a Uniform Manifold Approximation and Projection (UMAP) plot, constructed by Ne…
White Dwarf-Black Hole Binary Progenitors of Low Redshift Gamma-ray Bursts
Nicole M. Lloyd-Ronning, Jarrett L. Johnson, Phoebe R. Upton Sanderbeck +2
Although there is strong evidence that many long GRBs are associated with the collapse of a massive star, tantalizing results in recent years have upended the direct association of…
Using the COSMIC Population Synthesis Code to Investigate How Metallicity Affects the Rates of Interacting Binaries
Ayanah L. Cason, Nicole M. Lloyd-Ronning, Roseanne M. Cheng
We use COSMIC, a galaxy population synthesis code, to investigate how metallicity affects the rate of formation of massive stars with a closely orbiting compact object companion, t…
