Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
Early Ultra-Violet observations of type IIn supernovae constrain the asphericity of their circumstellar material
Maayane T. Soumagnac, Eran O. Ofek, Jingyi Liang +41
We present a survey of the early evolution of 12 Type IIn supernovae (SNe IIn) in the Ultra-Violet (UV) and visible light. We use this survey to constrain the geometry of the circu…
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…
Observations of Type Ia Supernova 2014J for Nearly 900 Days and Constraints on Its Progenitor System
Wenxiong Li, Xiaofeng Wang, Maokai Hu +18
We present extensive ground-based and () photometry of the highly reddened, very nearby type Ia supernova (SN Ia) 2014J in M82, covering the phases fr…
SN 2016hil-- a Type II supernova in the remote outskirts of an elliptical host and its origin
Ido Irani, Steve Schulze, Avishay Gal-Yam +14
Type II supernovae (SNe) stem from the core collapse of massive () stars. Owing to their short lifespan, we expect a very low rate of such events in elliptical host…
The Young and Nearby Normal Type Ia Supernova 2018gv: UV-Optical Observations and the Earliest Spectropolarimetry
Yi Yang, Peter A. Hoeflich, Dietrich Baade +25
The non-detection of companion stars in Type Ia supernova (SN) progenitor systems lends support to the notion of double-degenerate (DD) systems and explosions triggered by the merg…
