Identification of Basins of Attraction in the Local Universe
Aurelien Valade, Noam I. Libeskind, Daniel Pomarede +4
Structure in the Universe is believed to have evolved out of quantum fluctuations seeded by inflation in the early Universe. These fluctuations lead to density perturbations that g…
The large scale velocity field from the Cosmicflows-4 data
Yehuda Hoffman, Aurélien Valade, Noam I. Libeskind +5
The reconstruction of the large scale velocity field from the grouped Cosmicflows-4 (CF4) database is presented. The lognormal bias of the inferred distances and velocities data is…
A Local Universe model for constrained simulations
Simon Pfeifer, Aurélien Valade, Stefan Gottlöber +3
The aim of cosmological simulations is to reproduce the properties of the observed Universe, serving as tools to test structure and galaxy formation models. Constrained simulations…
Testing Bayesian reconstruction methods from peculiar velocities
Aurélien Valade, Noam I Libeskind, Yehuda Hoffman +1
Reconstructing the large scale density and velocity fields from surveys of galaxy distances, is a major challenge for cosmography. The data is very noisy and sparse. Estimated dist…
Constrained simulations of the local Universe with Modified Gravity
Krishna Naidoo, Wojciech A. Hellwing, Maciej Bilicki +3
We present a methodology for constructing modified gravity (MG) constrained simulations of the local Universe using positions and peculiar velocities from the CosmicFlows data set.…
COWS: A filament finder for Hessian cosmic web identifiers
Simon Pfeifer, Noam I. Libeskind, Yehuda Hoffman +3
The large scale galaxy and matter distribution is often described by means of the cosmic web made up of voids, sheets, filaments and knots. Many different recipes exist for identif…
