AstroNote 2024-250

We report the classification of 35 transients observed by different groups within the Zwicky Transient Facility (ZTF; Bellm et al. 2019; Graham et al. 2019). Classifications are mainly based on spectral matching using templates available within the Supernova Identification software (SNID; Blondin & Tonry 2008). In each case the redshift was estimated from the Halpha emission lines. Some of the events classified as "other" are consistent with AGNs although some can also be consistent with TDEs.  Analysis is presented in the ZTF SLSN II sample paper (Pessi et al., 2024).

This report is based on observations obtained with the 60-inch and 200-inch telescopes at the Palomar Observatory, the Keck I telescope at the W.M. Keck Observatory, and the 3.5-m telescope at the Apache Point Observatory.

ZTF is supported by the National Science Foundation under Grant No. AST-2034437 and a collaboration including Caltech, IPAC, the Weizmann Institute for Science, the Oskar Klein Center at Stockholm University, the University of Maryland, Deutsches Elektronen-Synchrotron and Humboldt University, the TANGO Consortium of Taiwan, the University of Wisconsin at Milwaukee, Trinity College Dublin, Lawrence Livermore National Laboratories, and IN2P3, France. Operations are conducted by COO, IPAC, and UW.
