Abstract
We construct a smooth moduli stack of genus one weighted curves with twisted fields. We show the moduli is isomorphic to Hu-Li's blowup stack of the moduli of genus one weighted curves. This leads to a modular interpretation of Vakil-Zinger's desingularization of the moduli of genus one stable maps to projective spaces. Our results should extend to resolutions of the moduli of stable maps of higher genera.
