TL;DR: In this article, 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 in a very faint (m_g = -14.10) host galaxy, were presented.

TL;DR: In this paper, 32 epochs of optical (3300-9700 A) spectrophotometric observations of the nearby quintessential "normal" type Ia supernova (SN Ia) SN 2011fe in the galaxy M101, extending from -15 to +97 d with respect to B-band maximum, obtained by the Nearby Supernova Factory collaboration.

TL;DR: In this article, a simulation of a delayed detonation in a Chandrasekhar-mass white dwarf and a violent merger of two white dwarfs-realizations of explosion models appropriate for two of the most widely-discussed progenitor channels that may give rise to SNe Ia is presented.
Journal ArticleDOI

TL;DR: In this article, the authors used the Nearby Supernova Factory (NSF) sample together with host galaxy data from \GALEX\ to independently confirm that result, with brightness differences of $0.094 \pm 0.037\ \mathrm{mag}

TL;DR: In this paper, the authors present a new atmospheric extinction curve for Mauna Kea spanning 3200-9700 AA, based on some 4285 standard star spectra obtained on 478 nights spread over a period of 7 years obtained by the Nearby Super Nova Factory using the SuperNova Integral Field Spectrograph.
