Abstract:
We present the Young Supernova Experiment Data Release 1 (YSE DR1),
comprised of processed multicolor PanSTARRS1 griz and Zwicky Transient
Facility (ZTF) gr photometry of 1975 transients with host-galaxy
associations, redshifts, spectroscopic and/or photometric
classifications, and additional data products from 2019 November 24 to
2021 December 20. YSE DR1 spans discoveries and observations from
young and fast-rising supernovae (SNe) to transients that persist for
over a year, with a redshift distribution reaching z∼0.5. We present
relative SN rates from YSE's magnitude- and volume-limited surveys,
which are consistent with previously published values within estimated
uncertainties for untargeted surveys. We combine YSE and ZTF data, and
create multisurvey SN simulations to train the ParSNIP and SuperRAENN
photometric classification algorithms; when validating our ParSNIP
classifier on 472 spectroscopically classified YSE DR1 SNe, we achieve
82% accuracy across three SN classes (SNe Ia, II, Ib/Ic) and 90%
accuracy across two SN classes (SNe Ia, core-collapse SNe). Our
classifier performs particularly well on SNe Ia, with high (>90%)
individual completeness and purity, which will help build an anchor
photometric SNe Ia sample for cosmology. We then use our photometric
classifier to characterize our photometric sample of 1483 SNe,
labeling 1048 (∼71%) SNe Ia, 339 (∼23%) SNe II, and 96 (∼6%) SNe
Ib/Ic. YSE DR1 provides a training ground for building discovery,
anomaly detection, and classification algorithms, performing
cosmological analyses, understanding the nature of red and rare
transients, exploring tidal disruption events and nuclear variability,
and preparing for the forthcoming Vera C. Rubin Observatory Legacy
Survey of Space and Time.
Description:
The Young Supernova Experiment (YSE) is a 3+ yr optical time-domain
survey observing with the 1.8m PS1 and Pan-STARRS2 (PS2) telescopes.
Both are equipped with 1.4 gigapixel cameras (GPC1 and GPC2) to
provide a 7deg2 field of view (FOV).
Currently, YSE has 7% total observing time allocation on PS1 and PS2
(but only PS1 data is in YSE DR1) to scan 750deg2 of sky with 3 day's
cadence in four 41 broadband filters grizP1. All YSE DR1 data
presented here are from PS1 in the period between 2019-November-24 and
2021-December-20.
We obtained complementing Zwicky Transient Facility (ZTF) observations
of YSE DR1 transients. The ZTF survey (Bellm+ 2019PASP..131a8002B 2019PASP..131a8002B) is
the successor to the PTF (Law+ 2009PASP..121.1395L 2009PASP..121.1395L). ZTF is housed at
the Palomar 48 inch Schmidt telescope, equipped with a 47deg2 FOV
camera and an 8s readout time, observing in three passbands: ZTF-g,
ZTF-r, and ZTF-i. See Section 3.

Note on tablec2.dat and tablec3.dat: The parameterization of supernova
intrinsic properties ("ParSNIP") classifier is from
Boone (2021AJ....162..275B 2021AJ....162..275B). ParSNIP is a hybrid physics-variational
autoencoder (VAE) architecture that models the intrinsic time varying
spectra of transients combined with an explicit physical model for
observational effects. See Section 5.
