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…
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…
A new method of measuring the peculiar velocity power spectrum
Pengjie Zhang, Albert Stebbins, Roman Juszkiewicz +1
We show that by directly correlating the cluster kinetic Sunyaev Zeldovich (KSZ) flux, the cluster peculiar velocity power spectrum can be measured to accuracy by future…
Optimal Moments for Velocity Fields Analysis
Hume A Feldman, Richard Watkins, Adrian Melott +1
We describe a new method of overcoming problems inherent in peculiar velocity surveys by using data compression as a filter with which to separate large-scale, linear flows from sm…
Velocity Fields as a Probe of Cosmology
Hume A Feldman
Analyses of peculiar velocity surveys face several challenges, including low signal--to--noise in individual velocity measurements and the presence of small--scale, nonlinear flows…
Morphological Measures of nonGaussianity in CMB Maps
Sergei F. Shandarin, Hume A. Feldman, Yongzhong Xu +1
We discuss the tests of nonGaussianity in CMB maps using morphological statistics known as Minkowski functionals. As an example we test degree-scale cosmic microwave background (CM…
