Alexei V. Filippenko,Michael Richmond,David Branch,Martin Gaskell,William Herbst,Charles H. Ford,Richard R. Treffers,Thomas Matheson,Luis C. Ho,Arjun Dey,Wallace L. W. Sargent,Todd Small,Wil van Breugel +12 more
TL;DR: In this article, photometric and spectroscopic observations of SN 1991bg, a very peculiar Type Ia supernova located in the outskirts of the E1 galaxy NGC 4374 (M84) in the Virgo cluster, were presented.
Journal ArticleDOI
Evidence for a Spectroscopic Sequence among Type Ia Supernovae
TL;DR: In this paper, a spectral sequence among Type Ia supernovae (SN Ia's) is presented based on the systematic variation of several features seen in the near-maximum light spectrum.
Journal ArticleDOI
A Critical Review of Selected Techniques for Measuring Extragalactic Distances
George H. Jacoby,David Branch,Robin Ciardullo,Roger L. Davies,William E. Harris,Michael J. Pierce,Christopher J. Pritchet,John L. Tonry,Douglas L. Welch +8 more
TL;DR: In this article, the authors review seven of the most reliable indicators used for deriving distances to galaxies as far way as 100 Mpc: globular-cluster luminosity functions (GCLF), novae, Type Ia supernovae (SN Ia), H I-line-width relations, planetary-nebula luminosity function (PNLF), surface-brightness fluctuations (SBF), and fundamental plane relationship for elliptical galaxies (Dn - sigma).
Journal ArticleDOI
In search of the progenitors of type ia supernovae
TL;DR: In this paper, a review of the candidate progenitor binary systems of Type Ia supernovae (SNe Ia) is presented, and it is shown that the exploding star is likely to be a mass accreting carbon-oxygen white dwarf.
Journal ArticleDOI
Evidence for a Spectroscopic Sequence Among SNe Ia
TL;DR: In this article, a spectral sequence among Type Ia supernovae (SNe Ia) was proposed based on the systematic variation of several features seen in the near-maximum light spectrum.
