SN 2025ogs: A Spectroscopically-Normal Type Ia Supernova at z = 2 as a Benchmark for Redshift Evolution
M. R. Siebert, J. D. R. Pierel, M. Engesser +20
The Nancy Grace Roman Space Telescope will provide a revolutionary measurement of the Universe's expansion kinematics, driven by dark matter and dark energy, out to .…
Testing for Intrinsic Type Ia Supernova Luminosity Evolution at z>2 with JWST
J. D. R. Pierel, D. A. Coulter, M. R. Siebert +38
The James Webb Space Telescope} (JWST) is opening new frontiers of transient discovery and follow-up at high-redshift. Here we present the discovery of a spectroscopically confirme…
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.…
