Cosmography of the Sloan Basin of Attraction and Neighborhood
Daniel Pomarede, R. Brent Tully, Aurelien Valade +2
The Sloan Great Wall is a dominant structure that is relatively nearby. As well as evident in redshift survey maps, its presence is manifested in distortions to cosmic expansion. H…
Constraining cosmological simulations with peculiar velocities: a forward-modeling approach
Aurélien Valade, Noam Libeskind, Daniel Pomarède +4
Numerical simulations are a key tool to decipher the dynamics of gravitation. Yet, they fail to spatially reproduce the Universe we observe, limiting comparison between observation…
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…
