The peculiar velocity correlation function of the Cosmicflows-4 catalog
Yuyu Wang, Hume A. Feldman, Richard Watkins +1
We present an analysis of the parallel peculiar velocity correlation function using data from the Cosmicflows-4 (CF4) survey. CF4 significantly extends the depth of the peculiar ve…
Improved Methods for Estimating Peculiar Velocity Correlation Functions Using Volume Weighting
Yuyu Wang, Sarah Peery, Hume A. Feldman +1
We present an improved method for calculating the parallel and perpendicular velocity correlation functions directly from peculiar velocity surveys using weighted maximum-likelihoo…
Peculiar Velocity Estimation from Kinetic SZ Effect using Deep Neural Networks
Yuyu Wang, Nesar Ramachandra, Edgar M. Salazar-Canizales +3
The Sunyaev-Zel'dolvich (SZ) effect is expected to be instrumental in measuring velocities of distant clusters in near future telescope surveys. We simplify the calculation of pecu…
The Peculiar Velocity Correlation Function
Yuyu Wang, Christopher Rooney, Hume A. Feldman +1
We present an analysis of the two-point peculiar velocity correlation function using data from the CosmicFlows catalogues. The Millennium and MultiDark Planck 2 N-body simulations…
Gravitational potential wells and the cosmic bulk flow
Abhinav Kumar, Yuyu Wang, Hume A. Feldman +1
The bulk flow is a volume average of the peculiar velocities and a useful probe of the mass distribution on large scales. The gravitational instability model views the bulk flow as…
