Jacob Wise (LJMU), Daniel Perley (LJMU), K-Ryan Hinds (LJMU), Zoe McGrath (LJMU) report/s a classification of object: SN 2025sno
Type: SN IaRedshift: 0.053
Remarks: Spectrum is well-fit by template spectra from previously classified SN Ia events. We also yield a fit to the SN IIb 2011fu, however the SN Ia fits are better and at a more appropriate phase. We therefore classify this event as a SN Ia, but also encourage further follow-up to confirm. Redshift of z = 0.053 ± 0.001 from host galaxy H-alpha. Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022).
The following Classification spectrum was provided:
