The Dark Energy Survey Supernova Program: A Reanalysis Of Cosmology Results And Evidence For Evolving Dark Energy With An Updated Type Ia Supernova Calibration

B. Popovic, P. Shah, W. D. Kenworthy +80

We present improved cosmological constraints from a re-analysis of the Dark Energy Survey (DES) 5-year sample of Type Ia supernovae (DES-SN5YR). This re-analysis includes an improv…

Feeling Blue: Constructing a Robust SALT3 UV Template and Constraining its Redshift Dependency

Qinan Wang, David O. Jones, Justin D. R. Pierel +13

Upcoming cosmological surveys will obtain numerous rest-frame ultraviolet (UV) observations of Type Ia supernovae (SNe Ia), yet there is concern about how standardizable SNe Ia are…

A Reassessment of the Pantheon+ and DES 5YR Calibration Uncertainties: Dovekie

B. Popovic, W. D. Kenworthy, M. Ginolin +21

Type Ia Supernovae (SNe Ia) are crucial tools to measure the accelerating expansion of the universe, comprising thousands of SNe across multiple telescopes. Accurate measurements o…

ZTF SN Ia DR2: Improved SN Ia colors through expanded dimensionality with SALT3+

W. D. Kenworthy, A. Goobar, D. O. Jones +24

Type Ia supernovae (SNe Ia) are a key probe in modern cosmology, as they can be used to measure luminosity distances at gigaparsec scales. Models of their light-curves are used to…

ZTF SN Ia DR2: Environmental dependencies of stretch and luminosity of a volume limited sample of 1,000 Type Ia Supernovae

M. Ginolin, M. Rigault, M. Smith +43

To get distances, Type Ia Supernovae magnitudes are corrected for their correlation with lightcurve width and colour. Here we investigate how this standardisation is affected by th…

ZTF SN Ia DR2: High-velocity components in the Si II 6355

L. Harvey, K. Maguire, U. Burgaz +27

The ZTF SN Ia Data Release 2 provides a perfect opportunity to perform a thorough search for, and subsequent analysis of, high-velocity components in the Si II 6355 feature in…
