dc.description.abstractWe report an analysis of a sample of 186 spectroscopically confirmed Type II supernova (SN) light curves (LCs) obtained from a combination of Zwicky Transient Facility (ZTF) and Asteroid Terrestrial-impact Last Alert System observations. We implement a method to infer physical parameters from these LCs using hydrodynamic models that take into account the progenitor mass, the explosion energy, and the presence of circumstellar matter (CSM). The CSM is modeled via the mass-loss rate, wind acceleration at the surface of the progenitor star with a beta velocity law, and the CSM radius. We also infer the time of explosion, attenuation (A (V) ), and the redshift for each SN. Our results favor low-mass progenitor stars (M (ZAMS )< 14 M-circle dot) with a dense CSM ( M > 10(-3) M-circle dot yr(-1), CSM radius similar to 10(15) cm, and beta > 2). Additionally, we find that the redshifts inferred from the SN LCs are significantly more accurate than those inferred using the host galaxy photometric redshift, suggesting that this method could be used to infer more accurate host galaxy redshifts from large samples of Type II SNe in the LSST era. Lastly, we compare our results with similar works from the literature.
