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…
Redshift Surveys and the Value of Omega
Hume A. Feldman, Adrian L. Melott
We compare the statistical properties of structures normal and transverse to the line of sight which appear in observational data from redshift surveys. We present a statistic whic…
Large Scale Velocity Fields Present and Future: Making Sense of the data
Hume A. Feldman
The large scale velocity field was sampled recently by two independent methods: the supernovae type Ia light curve shapes (Riess, Press \& Kirshner) and the Abell Cluster Catalog b…
