LUVCam: A high-performance, low-cost, UV/optical camera for the future of astronomy in space
Aaron Tohuvavohu, Suresh Sivanandam, Jean-Christophe Fronteddu +23
Astronomy-grade cameras with robust performance and heritage in the space environment have long been costly, substantially limiting capacity for space-based astronomy and creating…
Generalized Predictions for the Electromagnetic Signatures of Mirror Stars
Franco Cabral, Stuart Williamson, David Curtin +1
Mirror Stars are a generic prediction of dissipative dark matter models, including minimal atomic dark matter and twin baryons in the Mirror Twin Higgs. Mirror Stars capture regula…
Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc
Yanlong Shi, Liang Dai, Norman Murray +3
The lensed Sunburst Arc () hosts a young (--), massive (), compact () Lyman-continuum (LyC) le…
The Green Bank Ammonia Survey: Data Release 2
Jaime E. Pineda, Rachel K. Friesen, Erik Rosolowsky +22
We present an overview of the final data release (DR2) from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-formi…
Eccentricities of Close Stellar Binaries
Yanqin Wu, Sam Hadden, Janosz Dewberry +2
Orbits of stellar binaries are in general eccentric. These eccentricities encode information about their early lives. Here, we use thousands of main-sequence binaries from the Gaia…
Origin of high-velocity ejecta and early red excess emission in the infant Type Ia supernova 2021aefx
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +5
SN~2021aefx is a normal Type Ia Supernova (SN) with red excess emission over the first 2 days. We present detailed analysis of this SN using our high-cadence KMTNet multi-ba…
