Homogeneous Velocity‐Distance Data for Peculiar Velocity Analysis. III. The Mark III Catalog of Galaxy Peculiar Velocities [PDF]
The Astrophysical Journal Supplement Series, 1997 This is the third in a series of papers in which we assemble and analyze a homogeneous catalog of peculiar velocity data. In Papers I and II, we described the Tully-Fisher (TF) redshift-distance samples that constitute the bulk of the catalog, and our methodology for obtaining mutually consistent TF calibrations for these samples.

Cosmic string induced peculiar velocities [PDF]
The Astrophysical Journal, 1988 This paper considers the scenario of a flat universe with a network of heavy cosmic strings as the primordial fluctuation spectrum. The joint probability of finding streaming velocities of at least 600 km/s on large scales and local peculiar velocities of less than 800 km/s is calculated.

Peculiar velocities in dynamic spacetimes [PDF]
Physical Review D, 2014 We investigate the asymptotic behavior of peculiar velocities in certain physically significant time-dependent gravitational fields. Previous studies of the motion of free test particles have focused on the \emph{collapse scenario}, according to which a double-jet pattern with Lorentz factor $ \to \infty$ develops asymptotically along the direction of

Peculiar Velocities of Nearby Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 Over the last five years, enormous progress in accurate distance measurements for nearby galaxies has been attained. The Hubble Space Telescope allows us to estimate distances of about 7–10% accuracy using red giant branch (RGB) up to 8 Mpc. Now we have very accurate distances for more than 200 galaxies within ~6 Mpc.

The RMS Peculiar Velocity of Clusters [PDF]
, 1997 We study the rms peculiar velocity of clusters as a convenient statistic to put constraints on cosmological models. This statistic is easy to compute theoretically given a model for the power spectrum; we show that with some assumptions it can be directly related to the quantity $ _0^{0.6} _8$.

Peculiar velocities and the mean density parameter [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We study the peculiar velocity field inferred from the Mark III spirals using a new method of analysis. We estimate optimal values of Tully-Fisher scatter and zero-point offset, and we derive the 3-dimensional rms peculiar velocity ($ _v$) of the galaxies in the samples analysed.

A New Estimate of the Local Standard of Rest from Data on Young Objects
Open Astronomy, 2015 To estimate the peculiar velocity of the Sun with respect to the Local Standard of Rest (LSR), we use young objects in the Solar neighborhood with distance measurement errors within 10%–15%.
