An Accurate Analytic Model for the Thermal Sunyaev-Zel'dovich One-Point PDF
Leander Thiele, J. Colin Hill, Kendrick M. Smith
Non-Gaussian statistics of late-time cosmological fields contain information beyond that captured in the power spectrum. Here we focus on one such example: the one-point probabilit…
Transverse Velocities with the Moving Lens Effect
Selim C. Hotinli, Joel Meyers, Neal Dalal +6
Gravitational potentials which change in time induce fluctuations in the observed cosmic microwave background (CMB) temperature. Cosmological structure moving transverse to our lin…
Constraining local non-Gaussianities with kSZ tomography
Moritz Münchmeyer, Mathew S. Madhavacheril, Simone Ferraro +2
Kinetic Sunyaev Zel'dovich (kSZ) tomography provides a powerful probe of the radial velocity field of matter in the Universe. By cross-correlating a high resolution CMB experiment…
KSZ tomography and the bispectrum
Kendrick M. Smith, Mathew S. Madhavacheril, Moritz Münchmeyer +3
Several statistics have been proposed for measuring the kSZ effect by combining the small-scale CMB with galaxy surveys. We review five such statistics, and show that they are all…
Inflation and Early Dark Energy with a Stage II Hydrogen Intensity Mapping Experiment
Cosmic Visions 21 cm Collaboration, Réza Ansari, Evan J. Arena +29
This white paper envisions a revolutionary post-DESI, post-LSST dark energy program based on intensity mapping of the redshifted 21cm emission line from neutral hydrogen at radio f…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
