Full Nonlinear Velocity Reconstruction With Transformer and Ensemble Tree Machine Learning
Yulin Gong, Rachel Bean
Accurate reconstruction of peculiar velocities from galaxy positions is important for probing the motion and evolution of large scale structure. They are sensitive to the cosmologi…

B. Hadzhiyska, Y. Gong, Y. Hsu +55
We present a measurement of the pairwise kinematic Sunyaev-Zel'dovich (kSZ) signal using the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Sample (BGS) Data Release 1 (…
Cluster optical depth and pairwise velocity estimation using machine learning
Yulin Gong, Rachel Bean
We apply two machine learning methods, a CNN deep-leaning model and a gradient-boosting decision tree, to estimate individual cluster optical depths from observed properties derive…
