Black hole astrometric binaries in the Roman Galactic Bulge Time Domain Survey
Casey Y. Lam, Jessica R. Lu, Kareem El-Badry +6
The Nancy Grace Roman Space Telescope (Roman), NASA's next flagship mission, is currently scheduled to launch in August 2026. As part of its mission, Roman will conduct the Galacti…
An Updated SynthPop Model for Microlensing Simulations I: Model Description & Evaluation
Macy J. Huston, Alison L. Crisp, Marz Newman +21
The optimization and interpretation of microlensing surveys depends on having an accurate model of the Milky Way. However, existing population synthesis Galactic modeling tools oft…
Astrometric microlensing probes of the isolated neutron star population with Roman
Zofia Kaczmarek, Abby Halasi-Kun, Peter McGill +2
Notoriously hard to detect and study, isolated neutron stars (NS) could provide valuable answers to fundamental questions about stellar evolution and explosion physics. With the up…
Hints of an Anomalous Lens Population towards the Galactic Bulge
Scott E. Perkins, Peter McGill, William A. Dawson +4
The dark and dynamic parts of the Galaxy, including the bulk shape and movement of the Galactic Bulge and characteristics of dark compact object populations, such as a hypothetical…
On Finding Black Holes in Photometric Microlensing Surveys
Zofia Kaczmarek, Peter McGill, Scott E. Perkins +5
There are expected to be millions of isolated black holes in the Galaxy resulting from the death of massive stars. Measuring the abundance and properties of this remnant population…
popclass: a python package for classifying microlensing events
Greg Sallaberry, Zofia Kaczmarek, Peter McGill +3
popclass is a python package that provides a flexible, probabilistic framework for classifying the lens of a gravitational microlensing event. popclass allows a user to match chara…
Investigating the mixing between two black hole populations in LIGO-Virgo-KAGRA GWTC-3
Ming-Feng Ho, Scott Ellis Perkins, Simeon Bird +4
We introduce a population model to analyze the mixing between hypothesised power-law and Gaussian bump black hole populations in the latest gravitational wave cat…
Astrometric Microlensing by Primordial Black Holes with The Roman Space Telescope
James Fardeen, Peter McGill, Scott E. Perkins +5
Primordial Black Holes (PBHs) could explain some fraction of dark matter and shed light on many areas of early-universe physics. Despite over half a century of research interest, a…
Spatially resolved microlensing timescale distributions across the Galactic bulge with the VVV survey
Zofia Kaczmarek, Peter McGill, N. Wyn Evans +5
We analyze 1602 microlensing events found in the VISTA Variables in the Via Lactea (VVV) near-infrared (NIR) survey data. We obtain spatially-resolved, efficiency-corrected timesca…
Disentangling the Black Hole Mass Spectrum with Photometric Microlensing Surveys
Scott Ellis Perkins, Peter McGill, William Dawson +8
From the formation mechanisms of stars and compact objects to nuclear physics, modern astronomy frequently leverages surveys to understand populations of objects to answer fundamen…
