Early Shock Cooling Observations and Progenitor Constraints of Type IIb Supernova SN 2024uwq

We present early multiwavelength photometric and spectroscopic observations of the Type IIb supernova SN 2024uwq, capturing its shock-cooling emission phase and double-peaked light-curve evolution. Early spectra reveal broad H α ( v  ∼ 15,500 km s ^−1 ) and He I P Cygni profiles of similar strengths...
