Description

In this talk, I will present and discuss the evidence for an off-axis jet in the nearby broad-lined SN 2020bvc. Particular attention will be devoted to the modeling of the multi-wavelength late-time emission detected from this event, and on the signatures of cocoon emission in the very early spectra of this event.
