Presentation #117.06 in the session Time-Domain Astrophysics.
We present a sample of 42 broad-lined stripped-envelope supernovae (SNe Ic-BL) observed by the Zwicky Transient Facility, the largest sample of SNe 1c-BL events analyzed in literature thus far. We present the rgi light curves for each of the SNe, and estimate the host-galaxy extinction for each event through their g-r colors, along with deriving the explosion epochs for each of our events. Using spectra obtained around peak light, we compute expansion velocities from the Fe II line for each of the events through fitting 1c-BL templates to the spectra. We compute bolometric LCs through using Bolometric Correction coefficients dependent on the g-r colors, and study the blackbody temperature and radii evolution over time. We fit analytic models from Arnett (1982) to determine progenitor and explosion properties of the SNe, including their Nickel masses, ejecta masses, and kinetic energies. Out of the 42 events, 16 have robust radio follow-up coverage by VLA, presented in Corsi et al. (2022). We make systematic comparisons of the progenitor and explosion properties between events that are radio-loud against those that are radio-quiet, in order to see if inferences about relativistic ejecta and jet properties can be made solely from optical data.
