Watching a Star Explode with the Young Supernova Experiment

Event Information:

We present multi-wavelength observations of supernova (SN) 2020tlf, the first normal type II-P/L SN with confirmed precursor emission, as detected by the Young Supernova Experiment (YSE) transient survey. Soon after discovery, "flash" spectroscopy of SN 2020tlf with Keck LRIS revealed prominent narrow emission lines from shock-ionized circumstellar material (CSM) shedded in progenitor mass-loss episodes in the final months before explosion. Following classification, SN 2020tlf was observed in a thorough multi-wavelength follow-up campaign (x-ray to radio) out to 300 days after explosion.
