TL;DR: In this paper, photometric and spectroscopic observations of SN 2007if, an overluminous (M_V = −20.4), red (B-V = 0.16 at B-band maximum), slow-rising (t_(rise) = 24 days) type Ia supernova (SN Ia) in a very faint (m_g = −14.10) host galaxy.

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.

Greg Aldering,P. Antilogus,Stephen Bailey,C. Baltay,Amanda E. Bauer,N. Blanc,S. Bongard,Y. Copin,E. Gangler,S. Gilles,Richard Kessler,D. Kocevski,Brian C. Lee,S. C. Loken,Peter Nugent,R. Pain,E. Pecontal,R. Pereira,Saul Perlmutter,David Rabinowitz,G. Rigaudier,Richard Scalzo,G. Smadja,R. C. Thomas,Lifan Wang,B. A. Weaver +25 more
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.

TL;DR: In this paper, a new method was proposed to standardize type Ia supernova luminosities using flux ratios from a single flux-calibrated spectrum per supernova.
