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 Novel Optimal Transport-Based Approach for Interpolating Spectral Time Series: Paving the Way for Photometric Classification of Supernovae
M. Ramirez, G. Pignata, Francisco Förster +7
This paper introduces a novel method for creating spectral time series, which can be used for generating synthetic light curves for photometric classification but also for applicat…
