The GALEX-PTF experiment: II. supernova progenitor radius and energetics via shock-cooling modeling
Noam Ganot, Eran O. Ofek, Avishay Gal-Yam +6
The 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-co…
SN 2018fif: The Explosion of a Large Red Supergiant Discovered in Its Infancy by the Zwicky Transient Facility
Maayane T. Soumagnac, Noam Ganot, Ido Irani +32
High cadence transient surveys are able to capture supernovae closer to their first light than before. Applying analytical models to such early emission, we can constrain the proge…
Supernova PTF12glz: a possible shock breakout driven through an aspherical wind
Maayane T. Soumagnac, Eran O. Ofek, Avishay Gal-Yam +21
We present visible-light and ultraviolet (UV) observations of the supernova PTF12glz. The SN was discovered and monitored in near-UV and R bands as part of a joint GALEX and Paloma…
The detection rate of early UV emission from supernovae: A dedicated GALEX/PTF survey and calibrated theoretical estimates
Noam Ganot, Avishay Gal-Yam, Eran O. Ofek +22
The radius and surface composition of an exploding massive star,as well as the explosion energy per unit mass, can be measured using early UV observations of core collapse supernov…
