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…
spike: A tool to drizzle HST, JWST, and Roman PSFs for improved analyses
Ava Polzin
A point spread function (PSF) describes the distribution of light for a pure point source in an astronomical image due to the optics of the instrument. An accurate PSF is key for d…
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…
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…
Dinosaur in a Haystack : X-ray View of the Entrails of SN 2023ixf and the Radio Afterglow of Its Interaction with the Medium Spawned by the Progenitor Star (Paper 1)
A. J. Nayana, Raffaella Margutti, Eli Wiston +24
We present the results from our extensive hard-to-soft X-ray (NuSTAR, Swift-XRT, XMM-Newton, Chandra) and meter-to-mm wave radio (GMRT, VLA, NOEMA) monitoring campaign of the very…
