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 ...

Modelling turbulent deflagrations in type Ia supernovae

, 2005
We present an overview of the current state of multidimensional modelling of type Ia supernovae and an example for surprising consequences of impoving the physics of the model.

Spectra of High-Redshift Type Ia Supernovae and a Comparison with their Low-Redshift Counterparts

, 2005
Accepted for publication in AJ. Also available at http://supernova.lbl.gov/We present spectra for 14 high-redshift (0.17 < z < 0.83) supernovae, which were discovered by the Supernova Cosmology Project as part of a campaign to measure cosmological ...

Late Light Curves of Normally-Luminous Type Ia Supernovae [PDF]

, 2006
The use of Type Ia supernovae as cosmological tools has reinforced the need to better understand these objects and their light curves. The light curves of Type Ia supernovae are powered by the nuclear decay of 56Ni →56 Co →56 Fe.

Turbulence-Flame Interaction on the Early Evolution of Flames in Type Ia Supernovae

, 2011
Type Ia supernovae are bright stellar explosions thought to occur when a runaway thermonuclear reaction incinerates a compact star known as white dwarf (WD).

A Common Origin of Normal Type Ia Supernovae Suggested by the Photometric Diversity

The Astrophysical Journal
In recent years, with the increasing number of type Ia supernovae (SNe Ia) discovered soon after their explosions, a nonnegligible fraction of SNe Ia with early-excess emissions (EExSNe Ia) have been confirmed.

Connections Between the Spectroscopy and Photometry of Type Ia Supernovae [PDF]

Type Ia supernovae (SNe Ia) play a vital role in the study of many topics of astrophysics. They act as cosmological probes through their well-established nature as precise standardizable candles.

Type Ia Supernovae from First-generation Stars

The Astrophysical Journal
Type Ia supernovae (SNe Ia) discovered at redshift z ≲ 2.5 are presumed to be produced from Population I/II stars. In this work, we investigate the production of SNe Ia from Population III binaries in the cosmological framework.

The Hourglass Simulation: A Catalog for the Roman High-latitude Time-domain Core Community Survey

The Astrophysical Journal
We present a simulation of the time-domain catalog for the Nancy Grace Roman Space Telescope’s High-Latitude Time-Domain Core Community Survey. This simulation, called the Hourglass simulation, uses the most up-to-date spectral energy distribution models
