The Hourglass Simulation: A Catalog for the Roman High-Latitude Time-Domain Core Community Survey

B. M. Rose, M. Vincenzi, R. Hounsell +12

We present a simulation of the time-domain catalog for the Nancy Grace Roman Space Telescope's High-Latitude Time-Domain Core Community Survey. This simulation, called the Hourglas…

Towards Precision Photometric Type Ia Supernova Cosmology with Machine Learning

Helen Qu

The revolutionary discovery of dark energy and accelerating cosmic expansion was made with just 42 type Ia supernovae (SNe Ia) in 1999. Since then, large synoptic surveys, e.g., Da…

The Dark Energy Survey Supernova Program: Cosmological Analysis and Systematic Uncertainties

M. Vincenzi, D. Brout, P. Armstrong +93

We present the full Hubble diagram of photometrically-classified Type Ia supernovae (SNe Ia) from the Dark Energy Survey supernova program (DES-SN). DES-SN discovered more than 20,…

Probing the Consistency of Cosmological Contours for Supernova Cosmology

P. Armstrong, H. Qu, D. Brout +6

As the scale of cosmological surveys increases, so does the complexity in the analyses. This complexity can often make it difficult to derive the underlying principles, necessitati…

The Dark Energy Survey Supernova Program: Corrections on photometry due to wavelength-dependent atmospheric effects

J. Lee, M. Acevedo, M. Sako +64

Wavelength-dependent atmospheric effects impact photometric supernova flux measurements for ground-based observations. We present corrections on supernova flux measurements from th…
