Simulating the Formation of the Local Galaxy Population
H. Mathis, G. Lemson, V. Springel +4
We simulate the formation and evolution of the local galaxy population starting from initial conditions with a smoothed linear density field which matches that derived from the IRA…
Peculiar Velocity Reconstruction with Fast Action Method: Tests on Mock Redshift Surveys
Enzo Branchini, Amiram Eldar, Adi Nusser
We present extensive tests of the Fast Action Method (FAM) for recovering the past orbits of mass tracers in an expanding universe from their redshift-space coordinates at the pres…
The Large-Scale Tidal Velocity Field
Y. Hoffman, A. Eldar, S. Zaroubi +1
We present a method for decomposing the cosmological velocity field in a given volume into its divergent component due to the density fluctuations inside the volume, and its tidal…
Nonlinear Peculiar-Velocity Analysis and PCA
A. Dekel, A. Eldar, L. Silberman +1
We allow for nonlinear effects in the likelihood analysis of peculiar velocities, and obtain ~35%-lower values for the cosmological density parameter and for the amplitude of mass-…
Cosmological Density and Power Spectrum from Peculiar Velocities: Nonlinear Corrections and PCA
L. Silberman, A. Dekel, A. Eldar +1
We allow for nonlinear effects in the likelihood analysis of galaxy peculiar velocities, and obtain ~35%-lower values for the cosmological density parameter Om and the amplitude of…
Large-Scale Power Spectrum and Cosmological Parameters from SFI Peculiar Velocities
Wolfram Freudling, Idit Zehavi, Luiz N. da Costa +7
We estimate the power spectrum of mass density fluctuations from peculiar velocities of galaxies by applying an improved maximum-likelihood technique to the new all-sky SFI catalog…
POTENT Reconstruction from Mark III Velocities
A. Dekel, A. Eldar, T. Kolatt +5
We present an improved POTENT method for reconstructing the velocity and mass density fields from radial peculiar velocities, test it with mock catalogs, and apply it to the Mark I…
IRAS versus POTENT Density Fields on Large Scales: Biasing and Omega
Y. Sigad, A. Eldar, A. Dekel +2
The galaxy density field as extracted from the IRAS 1.2 Jy redshift survey is compared to the mass density field as reconstructed by the POTENT method from the Mark III catalog of…
