Early Light Curve Excess in Type IIb Supernovae Observed by the ATLAS Survey: Qualitative Constraints on Progenitor Systems
Bastian Ayala, Joseph P. Anderson, G. Pignata +8
Type IIb supernovae (SNe IIb) often exhibit an early light curve excess (EE) preceding the main peak powered by radioactive nickel decay. The physical origin of this early emission…

A Fast-Evolving, Luminous Transient Discovered by K2/Kepler
A. Rest, P. M. Garnavich, D. Khatami +12
For decades optical time-domain searches have been tuned to find ordinary supernovae, which rise and fall in brightness over a period of weeks. Recently, supernova searches have im…
