The Pantheon+ Analysis: SuperCal-Fragilistic Cross Calibration, Retrained SALT2 Light Curve Model, and Calibration Systematic Uncertainty
Dillon Brout, Georgie Taylor, Dan Scolnic +9
We present here a re-calibration of the photometric systems used in the Pantheon+ sample of Type Ia supernovae (SNe Ia) including those used for the SH0ES distance-ladder measureme…
A Reference Survey for Supernova Cosmology with the Nancy Grace Roman Space Telescope
B. M. Rose, C. Baltay, R. Hounsell +33
This note presents an initial survey design for the Nancy Grace Roman High-latitude Time Domain Survey. This is not meant to be a final or exhaustive list of all the survey strateg…
SALT3: An Improved Type Ia Supernova Model for Measuring Cosmic Distances
W. D. Kenworthy, D. O. Jones, M. Dai +13
A spectral-energy distribution (SED) model for Type Ia supernovae (SNe Ia) is a critical tool for measuring precise and accurate distances across a large redshift range and constra…
Synergies between Vera C. Rubin Observatory, Nancy Grace Roman Space Telescope, and Euclid Mission: Constraining Dark Energy with Type Ia Supernovae
B. M. Rose, G. Aldering, M. Dai +25
We review the needs of the supernova community for improvements in survey coordination and data sharing that would significantly boost the constraints on dark energy using samples…
The Foundation Supernova Survey: Photospheric Velocity Correlations in Type Ia Supernovae
Kyle G. Dettman, Saurabh W. Jha, Mi Dai +14
The ejecta velocities of type-Ia supernovae (SNe Ia), as measured by the Si II line, have been shown to correlate with other supernova properties, including color and stand…
