TNS Classification Report No. 23046 [ 2026TNSCR.764....1N ]
Date Received (UTC): 2026-02-23 18:12:09 Sender: Megan Newsome
Group: FLEET
Megan Newsome (UT Austin), Sebastian Gomez (UT Austin) report/s a classification of object: AT 2025ahbd
Type: TDERedshift: 0.336
Remarks: AT2025ahbd was selected as a possible TDE by our FLEET program with a P(TDE) = 0.59 (Gomez et al., 2023, ApJ, 949, 113). The redshift of z = 0.336 was determined from host features in the spectrum. At this redshift, the absolute magnitude in the g-band is currently M_g = -21.93. We find a best match to TDEs using SNID-SAGE (Stoppa et al. in prep: https://github.com/FiorenSt/SNID-SAGE). We note that good matches are also found to SLSN-II, but the persistent blue colors and nuclear location tentatively favor a TDE interpretation.
The following Classification spectrum was provided:
