SALT2 Versus SALT3: Updated Model Surfaces and Their Impacts on Type Ia Supernova Cosmology
G. Taylor, D. O. Jones, B. Popovic +6
For the past decade, SALT2 has been the most common model used to fit Type Ia supernova (SN Ia) light curves for dark energy analyses. Recently, the SALT3 model was released, which…
Propagating Uncertainties in the SALT3 Model Training Process to Cosmological Constraints
M. Dai, D. O. Jones, W. D. Kenworthy +5
Type Ia supernovae (SNe Ia) are standardizable candles that must be modeled empirically to yield cosmological constraints. To understand the robustness of this modeling to variatio…
SALT3-NIR: Taking the Open-Source Type Ia Supernova Model to Longer Wavelengths for Next-Generation Cosmological Measurements
J. D. R. Pierel, D. O. Jones, W. D. Kenworthy +32
A large fraction of Type Ia supernova (SN Ia) observations over the next decade will be in the near-infrared (NIR), at wavelengths beyond the reach of the current standard light-cu…
A Spectroscopic Model of the Type Ia Supernova--Host Galaxy Mass Correlation from SALT3
D. O. Jones, W. D. Kenworthy, M. Dai +4
The unknown cause of the correlation between Type Ia supernova (SN Ia) Hubble residuals and their host-galaxy masses (the "mass step") may bias cosmological parameter measurements.…
The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
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…
Understanding Type Ia Supernova Distance Biases by Simulating Spectral Variations
J. D. R. Pierel, D. O. Jones, M. Dai +7
In the next decade, transient searches from the Vera C. Rubin Observatory and the Nancy Grace Roman Space Telescope will increase the sample of known Type Ia Supernovae (SN Ia) fro…
SZ effect or Not? - Detecting most galaxy clusters' main foreground effect
Weike Xiao, Chen Chen, Bin Zhang +2
Galaxy clusters are the most massive objects in the Universe and comprise a high-temperature intracluster medium of about 10^7 K, believed to offer a main foreground effect for cos…
