Probing Cosmology through Higher-Order CMB Lensing Statistics
Shu-Fan Chen, J. Colin Hill, Zoltán Haiman
We investigate the cosmological information in higher-order statistics of the cosmic microwave background (CMB) lensing convergence field for a near-term experiment with noise prop…

Field-level Reconstruction from Foreground-Contaminated 21-cm Maps
Shu-Fan Chen, Kai-Feng Chen, Cora Dvorkin
Current and upcoming 21-cm experiments will soon be able to map 21-cm spatial fluctuations in three dimensions for a wide range of redshifts. However, bright foreground contaminati…

Constraining Dynamical Dark Energy from Galaxy Clustering with Simulation-Based Priors
Shu-Fan Chen, Mikhail M. Ivanov
The effective-field theory based full-shape analysis with simulation-based priors (EFT-SBP) is the novel analysis of galaxy clustering data that allows one to combine merits of per…
