A Simulation Based Inference Approach to Modelling of Type Ia Supernova Populations
B. Popovic, M. Grayling, M. O'Callaghan +12
Type Ia Supernovae (SNe Ia) are prominent cosmological probes, utilising a standardisation process to reduce their observed scatter to mag. A growing number of models se…
Chromatic Effects Across the Roman Focal Plane: Implications for Supernova Photometry and Measurements of Cosmological Parameters
Rujuta Purohit, Dillon Brout, Daniel Scolnic +14
Calibration uncertainties are the leading systematics in cosmological analyses using Type Ia supernovae (SNe Ia). For the \textit{Nancy Grace Roman Space Telescope (Roman)}, we qua…
Forward-modelling Milky Way Cepheids: selection effects and physical priors in the Gaia-HST calibration
Richard Stiskalek, Adam Riess, Harry Desmond +2
The advent of high-precision Gaia parallaxes for Milky Way Cepheids enables per cent-level calibration of the local distance ladder and the Hubble constant . We revisit the Mi…
Hawai`i Supernova Flows: Bulk Flow Measurements using SNe Ia in the Optical and NIR
Aaron Do, Kaisey S. Mandel, Benjamin J. Shappee +9
The present day peculiar velocity-field was sourced by primordial density fluctuations and sculpted over the lifespan of the Universe. Cosmological models such as CDM make pred…
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…
Constraints on Dynamical Dark Energy from Multiple Probes in the Full Dark Energy Survey
DES Collaboration, T. M. C. Abbott, M. Adamow +166
We present results on dark energy evolution, assuming a time-dependent equation of state , from growth and geometric probes using the full six-year Dark Energy S…
