Are Recent Peculiar Velocity Surveys Consistent? [PDF]
, 1999 We compare the bulk flow of the SMAC sample to the predictions of popular cosmological models and to other recent large-scale peculiar velocity surveys. Both analyses account for aliasing of small-scale power due to the sparse and non-uniform sampling of the surveys.

HVS 7: a chemically peculiar hyper-velocity star [PDF]
Astronomy & Astrophysics, 2008 Context: Hyper-velocity stars are suggested to originate from the dynamical interaction of binary stars with the supermassive black hole in the Galactic centre (GC), which accelerates one component of the binary to beyond the Galactic escape velocity. Aims: The evolutionary status and GC origin of the HVS SDSS J113312.12+010824.9 (HVS7) is constrained ...

Modelling peculiar velocities of dark matter haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 We present a simple model that accurately describes various statistical properties of peculiar velocities of dark matter halos. We pay particular attention to the following two effects; first, the evolution of the halo peculiar velocity depends on the local matter density, instead of the global density.

Wide-angle effects for peculiar velocities [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The line-of-sight peculiar velocities of galaxies contribute to their observed redshifts, breaking the translational invariance of galaxy clustering down to a rotational invariance around the observer. This becomes important when the line-of-sight direction varies significantly across a survey, leading to what are known as ‘wide-

The peculiar velocity correlation function [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We present an analysis of the two-point peculiar velocity correlation function using data from the CosmicFlows catalogues. The Millennium and MultiDark Planck 2 N-body simulations are used to estimate cosmic variance and uncertainties due to measurement errors. We compare the velocity correlation function to expectations from linear theory to constrain

Infall from peculiar velocities [PDF]
Proceedings of the International Astronomical Union, 2004 We perform a statistical analysis to study the infall of galaxies onto groups and clusters in the nearby Universe. The study is based on the UZC/SSRS2 group catalogs and galaxy peculiar velocity data. We find a clear signature of infall of galaxies onto groups in a large range of scales 5 Mpc h−1 < r < 30 Mpc h−1.
