The direct analysis of spectra of type Ia supernovae.

, 2000
By using SYNOW, we show that most of the spectroscopic differences among type Ia supernovae can be explained by the temperature; therefore, the composition of most of the type Ia supernovae is essentially the same.

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 ...

Photometric typing of normal and peculiar type Ia supernovae

, 2015
Indexación: ScopusWe present a new photometric typing technique for normal type Ia supernovae (SNe Ia) and peculiar SNe Ia such as SN 1991bg-like, type Iax and super-Chandrasekhar SNe Ia.

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

Spectroscopy of twelve Type Ia supernovae at intermediate redshift

, 2005
We present spectra of twelve Type Ia supernovae obtained in 1999 at the William Herschel Telescope and the Nordic Optical Telescope during a search for Type Ia supernovae (SN Ia) at intermediate redshift.

Testing the LSST Difference Image Analysis Pipeline Using Synthetic Source Injection Analysis

The Astrophysical Journal
We evaluate the performance of the Legacy Survey of Space and Time Science Pipelines Difference Image Analysis (DIA) on simulated images. By adding synthetic sources to galaxies on images, we trace the recovery of injected synthetic sources to evaluate ...

K-corrections and Extinction Corrections for Type Ia Supernovae [PDF]

, 2002
The measurement of the cosmological parameters from Type Ia supernovae hinges on our ability to compare nearby and distant supernovae accurately. Here we present an advance on a method for performing generalized K-corrections for Type Ia supernovae which

Carnegie Supernova Project: Fast-declining Type Ia Supernovae as Cosmological Distance Indicators

The Astrophysical Journal
In this paper, the suitability of fast-declining Type Ia supernovae (SNe Ia) as cosmological standard candles is examined utilizing a “Hubble Flow” sample of 43 of these objects observed by the Carnegie Supernova Project (CSP).
