Consistently Large Cosmic Flows on Scales of 100 Mpc/h: a Challenge for the Standard LCDM Cosmology

Richard Watkins, Hume A. Feldman, Michael J. Hudson

Peculiar velocity surveys have non-uniform spatial distributions of tracers, so that the bulk flow estimated from them does not correspond to that of a simple volume such as a sphe…

Cosmic Flows on 100 Mpc/h scales

Hume A. Feldman, Michael J. Hudson, Richard Watkins

To study galactic motions on the largest available scales, we require bulk flow moments whose window functions have as narrow a peak as possible and having as small an amplitude as…

Companions to Isolated Elliptical Galaxies: Revisiting the Bothun-Sullivan Sample

Barry F. Madore, Wendy L. Freedman, Gregory D. Bothun

(Abridged) We investigate the number of physical companion galaxies for a sample of relatively isolated elliptical galaxies. NED has been used to reinvestigate the incidence of sat…

Bulk Flow and Shear Moments of the SFI++ Survey

Hume A. Feldman, Richard Watkins

We find the nine bulk--flow and shear moments from the SFI++ survey, as well as for subsamples of group and field galaxies. We constrain the velocity power spectrum shape parameter…

Power Spectrum Shape from Peculiar Velocity Data

Richard Watkins, Hume A. Feldman

We constrain the velocity power spectrum shape parameter in linear theory using the nine bulk-flow and shear moments estimated from four recent peculiar velocity surveys. For e…

Current Status Of Velocity Field Surveys: A Consistency Check

Devdeep Sarkar, Hume A. Feldman, Richard Watkins

We present an analysis comparing the bulk--flow measurements for six recent peculiar velocity surveys, namely, ENEAR, SFI, RFGC, SBF and the Mark III singles and group catalogs. We…
