Abstract
We study a magnitude-limited sample of 36 Broad-lined Type Ic Supernovae (SNe
Ic-BL) from the Zwicky Transient Facility Bright Transient Survey, detected
between March 2018 and August 2021. We present the light curves (LCs) for each
of the SNe, and analyze the shape of the LCs to derive empirical parameters,
along with the explosion epochs for every event. The sample has an average
absolute peak magnitude in the r band of $M_r^{max}$ = -18.51 $\pm$ 0.15 mag.
Using spectra obtained around peak light, we compute expansion velocities from
the Fe II 5169 Angstrom line for each event with high enough signal-to-noise
ratio spectra, and find an average value of $v_{ph}$ = 16,100 $\pm$ 1,100 km
$s^{-1}$. We also compute bolometric LCs, study the blackbody temperature and
radii evolution over time, and derive the explosion properties of the SNe. The
explosion properties of the sample have average values of $M_{Ni}$ =
$0.37_{-0.06}^{+0.08}$ solar masses, $M_{ej}$ = $2.45_{-0.41}^{+0.47}$ solar
masses, and $E_K$= $4.02_{-1.00}^{+1.37} \times 10^{51}$ erg. Thirteen events
have radio observations from the Very Large Array, with 8 detections and 5
non-detections. We find that the populations that have radio detections and
radio non-detections are indistinct from one another with respect to their
optically-inferred explosion properties, and there are no statistically
significant correlations present between the events' radio luminosities and
optically-inferred explosion properties. This provides evidence that the
explosion properties derived from optical data alone cannot give inferences
about the radio properties of SNe Ic-BL, and likely their relativistic jet
formation mechanisms.
