Snowmass 2021 CMB-S4 White Paper
Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison +353
This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin a…
Probing the circumgalactic medium with CMB polarization statistical anisotropy
Anirban Roy, Alexander van Engelen, Vera Gluscevic +1
As cosmic microwave background (CMB) photons traverse the Universe, anisotropies can be induced via Thomson scattering (proportional to the integrated electron density; optical dep…
CCAT-prime Collaboration: Science Goals and Forecasts with Prime-Cam on the Fred Young Submillimeter Telescope
Prime collaboration, M. Aravena, J. E. Austermann +84
We present a detailed overview of the science goals and predictions for the Prime-Cam direct detection camera/spectrometer being constructed by the CCAT-prime collaboration for ded…
Constraining reionization with the first measurement of the cross-correlation between the CMB optical-depth fluctuations and the Compton y-map
Toshiya Namikawa, Anirban Roy, Blake D. Sherwin +2
We propose a new reionization probe that uses cosmic microwave background (CMB) observations; the cross-correlation between fluctuations in the CMB optical depth which probes the i…
CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
S4 Collaboration, Kevork Abazajian, Graeme E. Addison +233
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our underst…
The correlation of high-redshift galaxies with the thermal Sunyaev-Zel'dovich effect traces reionization
Eric J. Baxter, Lewis Weinberger, Martin Haehnelt +4
We explore a potential new probe of reionization: the cross-correlation of high-redshift galaxies with maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. We consider two types of…
Revised estimates of CMB -mode polarization induced by patchy reionization
Anirban Roy, Girish Kulkarni, P. Daniel Meerburg +4
The search for primordial gravitational waves through the -mode polarization pattern in the CMB is one of the major goals of current and future CMB experiments. Besides foregrou…
Cosmology With Low-Redshift Observations: No Signal For New Physics
Koushik Dutta, Anirban Roy, Ruchika +2
We analyse various low-redshift cosmological data from Type-Ia Supernova, Baryon Acoustic Oscillations, Time-Delay measurements using Strong-Lensing, measurements using Cosm…
Detectability of the -21cm cross-correlation: a tomographic probe of patchy reionization
Anirban Roy, Andrea Lapi, David Spergel +2
The cross-correlation between fluctuations in the electron scattering optical depth as probed by future Cosmic Microwave Background (CMB) experiments, and fluctuations…
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…
Beyond CDM with Low and High Redshift Data: Implications for Dark Energy
Koushik Dutta, Ruchika, Anirban Roy +2
Assuming that the Universe at higher redshifts (z \sim 4 and beyond) is consistent with LCDM model as constrained by the Planck measurements, we reanalyze the low redshift cosmolog…
