SALT: a spectral adaptive light curve template for type Ia supernovae

, 2005
We present a new method to parameterize type Ia Supernovae (SN Ia) multi-color light curves. The method was developed in order to analyze the large number of SN Ia multi-color light curves measured in current high-redshift projects.

Union through UNITY: Cosmology with 2000 SNe Using a Unified Bayesian Framework

The Astrophysical Journal
Type Ia supernovae (SNe Ia) were instrumental in establishing the acceleration of the Universe’s expansion. By virtue of their combination of distance reach, precision, and prevalence, they continue to provide key cosmological constraints, complementing ...

Recurrent novae: Single degenerate progenitors of Type Ia supernovae

, 2020
Type Ia supernovae are the result of explosive thermonuclear burning in CO white dwarfs. The progenitors of the Ia supernovae are white dwarfs in an interacting binary system.

TYPE Ia SUPERNOVAE AND THE HUBBLE CONSTANT

Annual Review of Astronomy and Astrophysics, 1998
▪ Abstract  The focus of this review is the work that has been done during the 1990s on using Type Ia supernovae (SNe Ia) to measure the Hubble constant (H0). SNe Ia are well suited for measuring H0. A straightforward maximum-light color criterion can weed out the minority of observed events that are either intrinsically subluminous or substantially ...

Characterizing the Roman Grism Redshift Efficiency of Type Ia Supernova Host Galaxies for the High-latitude Time-domain Survey

The Astrophysical Journal
The High-latitude Time-domain Survey (HLTDS) for the Nancy Grace Roman Space Telescope (Roman) will discover thousands of high-redshift Type Ia supernovae (SNe Ia) to set generation-defining cosmological constraints on dark energy. To construct the Roman
