Rate of caustic crossing microlensing events in stellar binary lenses with significant orbital motion

Arjun Murlidhar, B. Scott Gaudi, Todd. A. Thompson

Binary lens microlensing events in which the source crosses a caustic produce sharp, distinctive magnification peaks and can therefore be readily identified. In this paper, we expl…

Hidden in Plain Sight II: Characterizing the luminous companion to Kappa Velorum with VLTI/GRAVITY

D. M. Rowan, S. Kraus, Todd A. Thompson

Kappa Velorum (Markeb, HD 81188) is one of the brightest stars in the Southern sky and has long been known to be a single-lined spectroscopic binary. The binary mass function is la…

JWST Observations of Starbursts: PAHs Closely Trace the Cool Phase of M82's Galactic Wind

Sebastian Lopez, Colton Ring, Adam K. Leroy +30

Stellar feedback drives multiphase gas outflows from starburst galaxies, but the interpretation of dust emission in these winds remains uncertain. To investigate this, we analyze n…

Masses, Star-Formation Efficiencies, and Dynamical Evolution of 18,000 HII Regions

Debosmita Pathak, Adam K. Leroy, Ashley. T. Barnes +36

We present measurements of the masses associated with HII regions across 19 nearby star-forming galaxies by combining data from JWST, HST, MUSE, ALMA, VLA, and MeerKAT…

The structure and evolution of a high-mass stellar merger in the Hertzsprung gap

Rachel A. Patton, Marc H. Pinsonneault, Todd A. Thompson

Post-main-sequence binary mergers are a common evolutionary pathway for massive stars, but the effects of merging on the long-term structure and evolution of the resulting star are…

Observational Constraints on Cool Gas Clouds in M82's Starburst-Driven Outflow

Sebastian Lopez, Laura A. Lopez, Todd A. Thompson +2

Star formation feedback can drive large-scale, multi-phase galactic outflows. The dynamical and thermodynamical interaction between the hot and cooler phases is a prime focus of bo…

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…

Bursts of star formation and radiation-driven outflows produce efficient LyC leakage from dense compact star clusters

Shyam H. Menon, Blakesley Burkhart, Rachel S. Somerville +2

The escape of LyC photons emitted by massive stars from the dense interstellar medium of galaxies is one of the most significant bottlenecks for cosmological reionization. The esca…

Theory and Observation of Winds from Star-Forming Galaxies

Todd A. Thompson, Timothy M. Heckman

Galactic winds shape the stellar, gas, and metal content of galaxies. To quantify their impact, we must understand their physics. We review potential wind-driving mechanisms and ob…

H-alpha emission and HII regions at the locations of recent supernovae in nearby galaxies

Ness Mayker Chen, Adam K. Leroy, Sumit K. Sarbadhicary +22

We present a statistical analysis of the local, approximately 50-100 pc scale, H-alpha emission at the locations of recent (less than 125 years) supernovae (SNe) in nearby star-for…

Constraining the Diffusion Coefficient and Cosmic-Ray Acceleration Efficiency using Gamma-ray Emission from the Star-Forming Region RCW 38

Paarmita Pandey, Laura A. Lopez, Anna L. Rosen +3

Stellar winds from massive stars may be significant sources of cosmic rays (CRs). To investigate this connection, we report a detailed study of gamma-ray emission near the young Mi…
