Abstract:
We classify and re-classify a number of supernovae from the ZTF BTS, mostly old ones that are of the stripped envelope type.

We summarise the properties of the supernovae in the Related Objects Table.

 

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.

For credits, see that GCN: they state that For AT2020pv/ZTF20aaertpj, the GTC spectrum is consistent with a SN Ib close to maximum at redshift z = 0.026 +/- 0.006, consistent with the redshift of the host galaxy derived from the emission lines. 14:27:52.039 +33:34:09.68
