The Low-Mass Baryon Cycle in QUEST Dwarf Galaxies I: Sample definition and first results
Ava Polzin, Hsiao-Wen Chen, Zhijie Qu +3
We introduce the QUEST Dwarfs program, which connects low-mass galaxies' stellar populations, interstellar medium, and circumgalactic medium in a large and coherently analyzed samp…
On the universality of star formation efficiency in galaxies
Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov +1
We analyze high-resolution hydrodynamics simulations of an isolated disk dwarf galaxy with an explicit model for unresolved turbulence and turbulence-based star formation prescript…
Silkscreen: Direct Measurements of Galaxy Distances from Survey Image Cutouts
Tim B. Miller, Imad Pasha, Ava Polzin +1
With upcoming wide field surveys from the ground and space the number of known dwarf galaxies at Mpc is expected to dramatically increase. Insight into their nature a…
Forecasting Galaxy Cluster HI Mass Recovery with CHIME at Redshifts z = 1 and 2 via the IllustrisTNG Simulations
Ava Polzin, Laura Newburgh, Priyamvada Natarajan +1
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a drift-scan interferometer designed to map the entire northern sky every 24 hours. The all-sky coverage and sensitivi…
Modeling molecular hydrogen in low metallicity galaxies
Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov +1
We use a suite of hydrodynamics simulations of the interstellar medium (ISM) within a galactic disk, which include radiative transfer, a non-equilibrium model of molecular hydrogen…
A Nascent Tidal Dwarf Galaxy Forming within the Northern HI Streamer of M82
Imad Pasha, Deborah Lokhorst, Pieter G. van Dokkum +12
We identify a 600 pc-wide region of active star formation located within a tidal streamer of M82 via emission ( erg s cm), us…
Tidal Distortions in NGC1052-DF2 and NGC1052-DF4: Independent Evidence for a Lack of Dark Matter
Michael A. Keim, Pieter van Dokkum, Shany Danieli +11
Two ultra diffuse galaxies in the same group, NGC1052-DF2 and NGC1052-DF4, have been found to have little or no dark matter and to host unusually luminous globular cluster populati…
Simulating Eclipsing Binary Yields of the Rubin Observatory in the Galactic Field and Star Clusters
Aaron M. Geller, Ava Polzin, Andrew Bowen +1
We present a study of the detection and recovery efficiency of the Rubin Observatory for detached eclipsing binaries (EBs) in the galactic field, globular clusters (GCs) and open c…
A recently quenched isolated dwarf galaxy outside of the Local Group environment
Ava Polzin, Pieter van Dokkum, Shany Danieli +2
We report the serendipitous identification of a low mass (), isolated, likely quenched dwarf galaxy in the "foreground" of the COSMOS-CAN…
