Forecasting the Resolvability of Stellar Velocity Dispersions in Ultra-faint Dwarf Galaxies
Pierre Thibodeaux, Alex Drlica-Wagner, Alexander P. Ji +4
Ultra-faint dwarf galaxies (UFDs)---the smallest and most dark-matter dominated galactic systems---push the boundaries of our understanding of galaxy formation in the cold dark mat…
A Deep Look at the Ultra-Faint Milky Way Satellite Virgo III with Rubin Observatory Data Preview 2
Aashay Pai, Alex Drlica-Wagner, Peter S. Ferguson +10
We analyze the ultra-faint Milky Way satellite Virgo III using data from the Vera C. Rubin Observatory Data Preview 2 (DP2). Virgo III was observed in the Rubin "Cosmic Treasure Ch…
Discovery of the Distant, Ultra-Faint Milky Way Satellite Aquarius IV with the Vera C. Rubin Observatory Early Data Preview 2
William Cerny, Aashay Pai, Alex Drlica-Wagner +16
We present the discovery of Aquarius IV (Rubin J22010234) -- the first ultra-faint Milky Way satellite to be identified using data from the Vera C. Rubin Observatory. This syste…
Do Vision-Language Models See Dwarf Galaxies the Way We Do?
Dimitrios Tanoglidis, Chin Yi Tan, Kate Overdeck +1
With the advent of powerful, general-purpose vision-language models (VLMs), there has been growing interest in their potential to assist astronomical discovery, a field characteriz…
Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics
Ava Polzin, Katherine E. Whitaker, C. Megan Urry +85
Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated effi…
TDCOSMO 2025: Cosmological constraints from strong lensing time delays
TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30
We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…
Mixed Warm Dark Matter Constraints using Milky Way Satellite Galaxy Counts
Chin Yi Tan, Ariane Dekker, Alex Drlica-Wagner
Warm dark matter has been strongly constrained in recent years as the sole component of dark matter. However, a less-explored alternative is that dark matter consists of a mixture…
Project Dinos II: Redshift evolution of dark and luminous matter density profiles in strong-lensing elliptical galaxies across 0.1 < z < 0.9
William Sheu, Anowar J. Shajib, Tommaso Treu +5
We present a new measurement of the dark and luminous matter distribution of massive elliptical galaxies, and their evolution with redshift, by combining strong lensing and dynamic…
Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals
Chin Yi Tan, Anowar J. Shajib, Simon Birrer +7
The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The pow…
