The Zwicky Transient Facility (ZTF; Bellm et al. 2019; Graham et al. 2019) Superluminous Supernova Science Program (Lunnan et al. 2020; Yan et al. 2020; Chen et al. 2023a,b) reports 7 candidate SLSNe, following the methodology outlined by Perley et al. (in prep.)  We selected transients that have long rise time (>20 days) and/or faint host galaxies.

We summarise properties of the candidates in the Related Objects Table. These include coordinates, current magnitudes, approximate rise times, photometric redshifts of potential host galaxies (taken from the SDSS DR14) and special remarks.

Spectroscopic classifications and additional follow-up observations of these transients are encouraged.

This report is based on observations obtained with the Samuel Oschin Telescope 48-inch and the 60-inch Telescope at the Palomar Observatory as part of the Zwicky Transient Facility project. 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.
