Cosmo-Paleontology: Statistics of Fossil Groups in a Gravity-Only Simulation
Aurora Cossairt, Michael Buehlmann, Eve Kovacs +3
We present a detailed study of fossil group candidates identified in "Last Journey", a gravity-only cosmological simulation covering a volume with a…
The Dark Energy Survey Supernova Program: Cosmological biases from supernova photometric classification
M. Vincenzi, M. Sullivan, A. Möller +81
Cosmological analyses of samples of photometrically-identified Type Ia supernovae (SNe Ia) depend on understanding the effects of 'contamination' from core-collapse and peculiar SN…
Validating Synthetic Galaxy Catalogs for Dark Energy Science in the LSST Era
Eve Kovacs, Yao-Yuan Mao, Michel Aguena +36
Large simulation efforts are required to provide synthetic galaxy catalogs for ongoing and upcoming cosmology surveys. These extragalactic catalogs are being used for many diverse…
DESC DC2 Data Release Note
LSST Dark Energy Science Collaboration, Bela Abolfathi, Robert Armstrong +54
In preparation for cosmological analyses of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), the LSST Dark Energy Science Collaboration (LSST DESC) has created…
The Last Journey. II. SMACC -- Subhalo Mass-loss Analysis using Core Catalogs
Imran Sultan, Nicholas Frontiere, Salman Habib +4
This paper introduces SMACC -- Subhalo Mass-loss Analysis using Core Catalogs. SMACC adds a mass model to substructure merger trees based on halo "core tracking." Our approach avoi…
The Dark Energy Survey Supernova Program: Modelling selection efficiency and observed core collapse supernova contamination
M. Vincenzi, M. Sullivan, O. Graur +79
The analysis of current and future cosmological surveys of type Ia supernovae (SNe Ia) at high-redshift depends on the accurate photometric classification of the SN events detected…
