14853 2023-05-08 20:17:15 Sebastian Gomez Sebastian Gomez (STScI), Daichi Hiramatsu (Harvard CfA), Edo Berger (Harvard CfA), Peter Blanchard (Northwestern) FLEET SN Ia-CSM 0.17 1 FLEET 2023cpq was selected as a possible SLSN-I by our FLEET program with a P(SLSN-II) = 0.79 (Gomez et al., 2020, ApJ, 904, 74). We find a good match to SN Ia-CSM at around 60 days past peak. The redshift of z = 0.17 is determined assuming the broad emission like is H-alpha. Nevertheless, we also find reasonable matches to Type-I SLSNe at a similar phase, but in this case the redshift would be z = 0.19 and the broad emission line would correspond to [OI]. 2023TNSCR1029....1G
