The 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…

LIMFAST. IV. Learning High-Redshift Galaxy Formation from Multiline Intensity Mapping with Implicit Likelihood Inference
Guochao Sun, Tri Nguyen, Claude-André Faucher-Giguère +5
By opening up new avenues to statistically constrain astrophysics and cosmology with large-scale structure observations, the line intensity mapping (LIM) technique calls for novel…
