We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry 1975 transients with host-galaxy associations, redshifts, spectroscopic/photometric classifications, additional data products from 2019 November 24 to 2021 December 20. YSE DR1 spans discoveries observations young fast-rising supernovae (SNe) that persist for over a year, redshift distribution reaching z~0.5. relative...
Abstract We present pre- and postexplosion observations of the Type II-P supernova (SN II-P) 2019mhm located in NGC 6753. Based on optical spectroscopy photometry, we show that SN exhibits broad lines hydrogen with a velocity −8500 ± 200 km s −1 111 2 day extended plateau its luminosity, typical subclass. also fit late-time bolometric light curve infer it initially produced 56 Ni mass 1.3 × 10 −2 5.5 −4 M ⊙ . Using imaging from Wide Field Planetary Camera Hubble Space Telescope obtained 19...
Characterizing the host galaxies of astrophysical transients is important to many areas astrophysics, including constraining progenitor systems core-collapse supernovae, correcting Type Ia supernova distances, and probabilistically classifying without photometric or spectroscopic data. Given increasing transient discovery rate in coming years, there substantial utility providing public, transparent, reproducible, automatic characterization for large samples galaxies. Here we present Blast, a...
