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…
