cds-question@unistra.frsupernovaeultraviolet-photometryvisible-astronomyredshiftedThe radius and surface composition of an exploding massive star, as well as the explosion energy per unit mass, can be measured using early ultraviolet (UV) observations of core-collapse supernovae (CC SNe). We present the results from a simultaneous Galaxy Evolution Explorer (GALEX) and Palomar Transient Factory (PTF) search for early UV emission from SNe. We analyze five CC SNe for which we obtained near-UV (NUV) measurements before the first ground-based R-band detection. We introduce SOPRANOS, a new maximum likelihood fitting tool for models with variable temporal validity windows, and use it to fit the Sapir & Waxman (2017ApJ...838..130S) shock-cooling model to the data. We report four Type II SNe with progenitor radii in the range of R_*_~600-1100R_{sun}_ and a shock velocity parameter in the range of v_s*_~2700-6000km/s (E/M~2-8x10^50^erg/M_{sun}_) and one Type IIb SN with R_*_~210R_{sun}_ and v_s*_~11000km/s (E/M~1.8x10^51^erg/M_{sun}_). Our pilot GALEX/PTF project thus suggests that a dedicated, systematic SN survey in the NUV band, such as the wide-field UV explorer ULTRASAT mission, is a compelling method to study the properties of SN progenitors and SN energetics.2022ApJ...931...71Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/931/71CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/395/1409 : Type II-P SN progenitor constraints (Smartt+, 2009)J/ApJ/742/L18 : Follow-up photometry of the SN IIb PTF 11eon (Arcavi+, 2011)J/ApJ/736/159 : Photometry monitoring of the SN PTF10vdl (Gal-Yam+, 2011)J/MNRAS/438/L101 : First month on SN 2013ej (Valenti+, 2014)J/MNRAS/446/3895 : The rising light curves of Type Ia supernovae (Firth+, 2015)J/A+A/574/A60 : Light curve templates of SNe Ib/c from SDSS (Taddia+, 2015)J/ApJ/820/33 : R-band light curves of type II supernovae (Rubin+, 2016)J/MNRAS/478/3138 : Luminous supergiants in Magellanic Clouds (Davies+, 2018)J/ApJ/861/63 : Type IIP SN 2016bkv LCs and spectra (Hosseinzadeh+, 2018)J/ApJ/902/6 : UV to visible-light obs. of SN 2018fif (Soumagnac+, 2020)J/ApJS/255/29 : PTF core-collapse SN host-galaxy sample.
