Fast Lensing And Sub-minute High-accuracy photometry (FLASH) with JWST: Pipeline and Primordial Black Hole Microlensing Constraints from M31

David Rubin, Istvan Szapudi

Minute- and sub-minute microlensing provides a direct probe of compact dark matter at asteroid-mass scales, where primordial black holes with MPBH <~ 10^-10 Msol would produce shor…

Testing CDM versus dynamical dark energy in one year: A DESI spectroscopic follow-up program for Rubin supernovae

Jannik Truong, Greg Aldering, Saul Perlmutter +2

Combined cosmological probes currently indicate that best-fit values in the parametrization of dynamical dark energy deviate from CDM by . In this work, we pre…

Banana Split: Improved Cosmological Constraints with Two Light-Curve-Shape and Color Populations Using Union3.1+UNITY1.8

David Rubin, Taylor Hoyt, Greg Aldering +1

SNe Ia have been used to provide key constraints on the equation-of-state parameter of dark energy. They are generally standardized under the assumption that they belong to a singl…

Union3.1: Reducing Systematics in Supernova Cosmology with Self-consistent Measurements of Host Galaxy Properties for 2000 Type Ia Supernovae

Taylor J. Hoyt, David Rubin, Greg Aldering +3

Photometrically derived distances of Type Ia supernovae (SNe Ia) rely on a empirical correction based on host galaxy properties, e.g., global stellar mass. Unbiased cosmo…

Three-dimensional scene reconstruction using Roman slitless spectra

Tri L. Astraatmadja, Andrew S. Fruchter, Susana E. Deustua +10

The Nancy Grace Roman Space Telescope will carry out a wide-field imaging and slitless spectroscopic survey of Type Ia Supernovae to improve our understanding of dark energy. Cruci…

Union Through UNITY: Cosmology with 2,000 SNe Using a Unified Bayesian Framework

David Rubin, Greg Aldering, Marc Betoule +8

Type Ia supernovae (SNe Ia) were instrumental in establishing the acceleration of the universe's expansion. By virtue of their combination of distance reach, precision, and prevale…
