The optimal redshift for dark energy II: application to cosmological data and the evidence for the phantom crossing of the CPL equation of state
Travis Seth Rippentrop, Mustapha Ishak, Kristian Gonzalez
Recent results from DESI and other cosmological datasets have indicated a preference for dynamical dark energy, with a time-evolving equation of state (EOS), . Furthermore, a…
The optimal redshift for dark energy I: formalism and interpretation
Mustapha Ishak, Travis Seth Rippentrop, Kristian Gonzalez
We introduce the concept of the optimal redshift for dark energy, a statistically motivated redshift at which departures of the dark-energy equation of state (EOS) from the cosmolo…
Opportunities in AI/ML for the Rubin LSST Dark Energy Science Collaboration
LSST Dark Energy Science Collaboration, Eric Aubourg, Camille Avestruz +63
The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will produce unprecedented volumes of heterogeneous astronomical data (images, catalogs, and alerts) that cha…
Extracting intrinsic alignments in the Dark Energy Survey's year 1 data, using the self-calibration method and LSST-DESC tools
Eske M. Pedersen, Leonel Medina-Varela, Emily Phillips Longley +4
We present the implementation of a Self-Calibration of Intrinsic Alignments of galaxies as an extension to the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) Da…
