Supernovae Unite: Host-Galaxy Mass Measurements of Type Ia Supernovae and Their Impact on Cosmology

J. Lee, R. Camilleri, T. M. Davis +22

Current consensus suggests that Type Ia supernova (SN Ia) brightnesses post light-curve standardization correlate with their host-galaxy stellar masses, which must be accounted for…

Flux Cube Reconstruction from Slitless Spectroscopy

M. Griggio, R. E. Ryan, N. Pirzkal +19

Slitless spectroscopy enables efficient, large-area surveys without target pre-selection, yet it faces challenges from source blending, higher noise, and lost spatial-spectral info…

Cosmological Parameter Uncertainties from SALT-II Type Ia Supernova Light Curve Models

J. Mosher, J. Guy, R. Kessler +11

We use simulated SN Ia samples, including both photometry and spectra, to perform the first direct validation of cosmology analysis using the SALT-II light curve model. This valida…
