Sara Faris (TAU), Hugo Tranin (UB), Moira Andrews(Las Cumbres), Iair Arcavi (TAU) report/s a classification of object: SN 2025adjc
Type: SN IaRedshift: 0.028563
Remarks: Using SNID-SAGE (Stoppa et al., in prep.), we find that the heavily host-contaminated spectrum of AT 2025adjc is best matched by a late-phase Type Ia SN at the host galaxy redshift z = 0.028563 (from NED; da Costa et al. 1998, AJ, 116, 1), which is consistent with the observed narrow Ca II H&K absorption in the spectrum.
The following Classification spectrum was provided:
