TL;DR: In this article, the authors reported the independent discovery and follow-up observations of supernova 2005gj by the Nearby Supernova Factory, which is the second case of a hybrid Type Ia/IIn supernova, which like the prototype SN 2002ic, was inter- pret as the explosion of a white dwarf interacting with a circumstellar medium.

TL;DR: The Nearby Supernova Factory (SNfactory) as mentioned in this paper is an international experiment designed to lay the foundation for the next generation of cosmology experiments (such as CFHTLS, wP, SNAP and LSST) which will measure the expansion history of the Universe using Type Ia supernovae.

TL;DR: The second confirmed case of a hybrid Type Ia/IIn supernova, SN 2005gj, was observed in this paper, where the early spectrum showed a hot continuum with broad and narrow H-alpha emission.
