Title: Explosions in my data

While astronomy is largely considered a pioneering discipline in data science and big data, several topics of astronomical inference still suffer from scarcity and inhomogeneity of data. This picture will change dramatically in the next decade.
Stripped envelope supernovae, inch include SN Ib, Ic, IIb and broad lined Ic SN, are a neglected sibling of cosmological star explosions, and thus far had largely been overlooked observationally, surveys often moving on as an object was discovered not to be cosmological SN. Stripped SN are the death throes of massive stars, and are connected to GRB explosions in way yet to be fully understood. With the largest photometric and spectroscopic dataset of stripped SN to date in hand (Bianco+ 2014, Modjaz+ 2014), we move from a more traditional event by event approach to a statistical study of explosion observables in order to confront the problem of connecting explosions to their progenitors. This way we are setting the stage for analyses that will be enabled by the wealth of data that the next generation time domain surveys will provide.
