Evidence for a low-density universe from the relative velocities of galaxies
The motions of galaxies can be used to constrain the cosmological density parameter Omega and the clustering amplitude of matter on large scales. The mean relative velocity of galaxy pairs, estimated from the Mark III survey, indicates that Omega = 0.35(-0.25)(+0.35). If the clustering of galaxies is unbiased on large scales, Omega = 0. 35 +/- 0.15, so that an unbiased Einstein-de Sitter model ...
متن کاملEMISSION-LINE OBJECTS FROM A PRELIMINARY UKST OBJECTIVE PRISM SURVEY
A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...
متن کاملFrom Velocities in Voids
We propose a method for deriving a dynamical lower bound on from diverging ows in low-density regions, based on the fact that large outtows are not expected in a low-universe. The velocities are assumed to be induced by gravity from small initial uctuations, but no assumptions are made regarding their exact Gaussian nature, galaxy biasing, or. The derivatives of a diverging velocity eld infer a...
متن کاملLinear Redshift Distortions
Redshift maps of galaxies in the Universe are distorted by the peculiar velocities of galaxies along the line of sight. The amplitude of the distortions on large, linear scales yields a measurement of the linear redshift distortion parameter, which is β ≈ Ω 0.6 0 /b in standard cosmology with cosmological density Ω 0 and light-to-mass bias b. All measurements of β from linear redshift distortio...

There is substantial evidence that most of the matter of the universe is dark and a compelling motivation to believe that it is mainly of non-baryonic origin [1, 2, 3, 4, 5, 6, 7]. The flat rotation curves in spiral galaxies indicate that most of their masses is in form of large Dark Matter (DM) halos of a mass ten times bigger than the visible mass. Dynamical evidence for the existence of DM a...
