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…
Towards Neutrino Mass from Cosmology without Optical Depth Information
Byeonghee Yu, Robert Z Knight, Blake D. Sherwin +3
With low redshift probes reaching unprecedented precision, uncertainty of the CMB optical depth is expected to be the limiting factor for future cosmological neutrino mass constrai…
Probing Gravitational Lensing of the CMB with SDSS-IV Quasars
Jiashu Han, Simone Ferraro, Elena Giusarma +1
We study the cross-correlation between the Planck CMB lensing convergence map and the eBOSS quasar overdensity obtained from the Sloan Digital Sky Survey (SDSS) IV, in the redshift…
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…
Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey II: Report of a Community Workshop on the Scientific Synergies Between the SPHEREx Survey and Other Astronomy Observatories
Olivier Doré, Michael W. Werner, Matthew L. N. Ashby +60
SPHEREx is a proposed NASA MIDEX mission selected for Phase A study. SPHEREx would carry out the first all-sky spectral survey in the near infrared. At the end of its two-year miss…
