Yuhan Yao (Caltech), Suvi Gezari (STScI), Sjoert van Velzen (Leiden), Erica Hammerstein (UMD), Jean Somalwar (Caltech) report/s a classification of object: TDE 2022gri
Type: TDERedshift: 0.028
Remarks: AT2022gri/ZTF20aahmtso is a nuclear transient selected from ZTF. The ZTF+ATLAS forced photometry light curve suggests a long rise time of >50 days and persistent blue colors. An optical spectrum obtained on 2022 April 22 shows galaxy absorption lines at z=0.028 and a blue continuum, which suggests that AT2022gri is probably a nearby TDE.
