, 2016 Type Ia supernovae play an important role in many areas of astrophysics, as extragalactic distance indicators and the most mature probes of cosmic acceleration, as the main producers of iron in the Universe, as end points of stellar evolution, and as contributors to the chemical evolution of galaxies.

Abundance Tomography of Type Ia Supernovae [PDF]
, 2004 Many uncertainties about the physics of Type Ia Supernovae have been revealed in the recent past, and numerous pieces are puzzled together to achieve a complete description of the phenomenon of thermonuclear explosions in the sky. However, very important parts are still missing.

Rates and Progenitors of Type Ia Supernovae [PDF]
, 2004 The remarkable uniformity of Type Ia supernovae (SNe Ia) has allowed astronomers to use them as distance indicators to measure the properties and expansion history of the Universe. However, SNe Ia exhibit intrinsic variation in both their spectra and observed brightness.

A problem with the analysis of type Ia supernovae
Open Astronomy, 2017 Type Ia supernovae have light curves that have widths and magnitudes that can be used for testing cosmologies and they provide one of the few direct measurements of time dilation.

EAS Publications Series, 2008 Type Ia supernovae are thought to be the outcome of the thermonuclear explosion of a carbon–oxygen white dwarf in a close binary system. In this review we discuss the observational background, the possible progenitors, the mechanisms leading to the instability and the development of the explosion itself as well as the remaining uncertainties.

The Spatial Distribution of Type Ia Supernovae within Host Galaxies
The Astronomical JournalWe study how type Ia supernovae (SNe Ia) are spatially distributed within their host galaxies, using data taken from the Sloan Digital Sky Survey (SDSS).

Carnegie Supernova Project: Classification of Type Ia Supernovae [PDF]
The Astrophysical Journal, 2020 Abstract We use the spectroscopy and homogeneous photometry of 97 Type Ia supernovae (SNe Ia) obtained by the Carnegie Supernova Project as well as a subset of 36 SNe Ia presented by Zheng et al. to examine maximum-light correlations in a four-dimensional (4D) parameter space: B-band absolute magnitude, M

The Hubble Constant from Blue Type Ia Supernovae
The Astrophysical JournalThere is a persistent tension of about 5 σ –6 σ between the value of the Hubble constant, as derived from the local distance ladder versus the cosmic microwave background, signaling either unaccounted for systematics in the measurements or “new physics,”

The Progenitors of Type Ia Supernovae [PDF]
Symposium - International Astronomical Union, 2003 Using binary population synthesis (BPS), we studied the birthrates of SNe Ia for two progenitor models – the single degenerate model and the double degenerate model. We find that the birthrates from both models are within a factor of a few comparable to those inferred observationally.

The Progenitors of Type Ia Supernovae [PDF]
The Astrophysical Journal, 2008 Type Ia supernovae (SNe Ia) occur in both old, passive galaxies and active, star-forming galaxies. This fact, coupled with the strong dependence of SN Ia rate on star formation rate, suggests that SNe Ia form from stars with a wide range of ages. Here we show that the rate of SN Ia explosions is about 1% of the stellar death rate, independent of star ...
