Discovery of over a thousand variable stars in Terzan 5 and Liller 1 with JWST
Kevin B. Burdge, Ilaria Caiazzo, Malina M. Desai +18
The Bulge Fossil Fragments Terzan 5 and Liller 1 host some of the densest stellar environments in the Galaxy, yet their variable star populations have remained largely unexplored d…
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…
Expanding the SPISEA Stellar Population Synthesis Software to the Substellar Regime
Caitlin Begbie, Rachel Street, Katarzyna Kruszynska +4
We present an extension of the SPISEA stellar population synthesis framework that adds brown dwarfs to the existing range of stellar mass objects, enabling physically consistent mo…
An HST Wide Field Survey of the Galactic Bulge: Overview, Strategy, and First Results
Sean K. Terry, Jay Anderson, Charles A. Beichman +13
We present an HST imaging survey of a 1.1 sq. degree sky area toward the Milky Way Galactic Bulge. This field significantly overlaps with the upcoming Nancy Grace Roman Galactic Bu…
First Observation of CO Emission and foreground absorption Toward the Galactic Center with JWST
J. Qiu, A. Ciurlo, M. R. Morris +11
CO is an important, stable, and abundant molecule in the Universe, but it is very difficult to detect because it has no observable pure rotational transitions. The unique sensi…
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…
Assessing the Impact of Binary Systems on Microlensing Using SPISEA and PopSyCLE Population Simulations
Natasha S. Abrams, Jessica R. Lu, Casey Y. Lam +3
Gravitational microlensing provides a unique opportunity to probe the mass distribution of stars, black holes, and other objects in the Milky Way. Population simulations are necess…
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…
Precise and Accurate Mass and Radius Measurements of Fifteen Galactic Red Giants in Detached Eclipsing Binaries
D. M. Rowan, K. Z. Stanek, C. S. Kochanek +9
Precise and accurate mass and radius measurements of evolved stars are crucial to calibrating stellar models. Stars in detached eclipsing binaries (EBs) are excellent potential cal…
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…
The Galactic Center in Color: Measuring Extinction with High-Proper-Motion Stars
Z. Haggard, A. M. Ghez, S. Sakai +6
The Milky Way's central parsec is a highly extinguished region with a population of high-proper-motion stars. We have tracked 145 stars for 10 years at wavelengths between 1…
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…
The 3D Kinematics of the Orion Nebula Cluster II: Mass-dependent Kinematics of the Inner Cluster
Lingfeng Wei, Christopher A. Theissen, Quinn M. Konopacky +3
We present the kinematic analysis of stars within $4\mbox{$^\prime$}$ from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formati…
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…
Microlensing Discovery and Characterization Efficiency in the Vera C. Rubin Legacy Survey of Space and Time
Natasha S. Abrams, Markus P. G. Hundertmark, Somayeh Khakpash +11
The Vera C. Rubin Legacy Survey of Space and Time will discover thousands of microlensing events across the Milky Way Galaxy, allowing for the study of populations of exoplanets, s…
Primordial Black Hole Dark Matter Simulations Using PopSyCLE
K. Pruett, W. Dawson, M. S. Medford +6
Primordial black holes (PBHs), theorized to have originated in the early universe, are speculated to be a viable form of dark matter. If they exist, they should be detectable throu…
