YSE Gemini Large and Long Program Data Release

Keywords: Supernova, Surveys, Spectroscopy, Transient, Time-domain
Abstract:
The Young Supernova Experiment (YSE) collaboration reports the results and data products from the completed Gemini Large and Long Program (LP-204) entitled "A Spectroscopically Complete Census of Faint Transients Observed by the Young Supernova Experiment."

The Young Supernova Experiment (YSE; Jones+ 2021) reports the completion and data release associated with the Large and Long Program (LP-204) entitled "A Spectroscopically Complete Census of Faint Transients Observed by the Young Supernova Experiment." Observations were performed with the Gemini Multi-Object Spectrograph (GMOS) at Gemini South Observatory from semesters 21B-24A with the exception of the 23A (partial) and 23B (all) semesters, which were affected by the cyber attack. A total of 87 observations were conducted through this program, resulting in 84 successful optical spectra of supernovae discovered and/or monitored by the YSE survey. Below we list the supernovae observed in this program. For 66 observations, we have uploaded the resulting GMOS-S spectra to the corresponding object pages on TNS; the remaining spectra from this LLP will be made public following the publication of papers in preparation. We are grateful to the Gemini observers who carried out these observations.
