The $I ¨ $ of Neutral Hydrogen: Increased CMB Optical Depth at Long Wavelengths

Gilbert Holder, Adrian Liu, Tzu-Ching Chang +1

At wavelengths longer than 21 cm, photons from the long-wavelength tail of the cosmic microwave background (CMB) have a non-zero probability of being absorbed by distant neutral hy…

Gravitational Lensing of Galaxy Clustering

Brandon Buncher, Gilbert Holder, Selim Hotinli

We investigate lensing reconstruction using the clustered galaxy distribution as a source field, using both the traditional cosmic microwave background quadratic estimator and a sh…

Cosmological information content of Betti curves and $k$ -nearest neighbor distributions

Aaron Ouellette, Gilbert Holder

We compare the cosmological constraints that can be obtained from halo clustering on non-linear scales ( $2 h^{- 1}$ Mpc < $r$ < $50 h^{- 1}$ Mpc) using Betti curves, a topological su…
