BICEP / Keck XVII: Line of Sight Distortion Analysis: Estimates of Gravitational Lensing, Anisotropic Cosmic Birefringence, Patchy Reionization, and Systematic Errors

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We present estimates of line-of-sight distortion fields derived from the 95 GHz and 150 GHz data taken by BICEP2, BICEP3, and Keck Array up to the 2018 observing season, leading to cosmological constraints and […]

Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era

Posted by Chicago

Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, The LSST Dark Energy Science Collaboration | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts […]

BICEP / Keck XVI: Characterizing Dust Polarization through Correlations with Neutral Hydrogen

Posted by Stanford

Kavli Affiliate: C. L. Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We characterize Galactic dust filaments by correlating BICEP/Keck and Planck data with polarization templates based on neutral hydrogen (H I) observations. Dust polarization is important for both our understanding of astrophysical processes in […]

Role of the Hubble Scale in the Weak Lensing vs. CMB Tension

Posted by Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: Lucas F. Secco, Tanvi Karwal, Wayne Hu, Elisabeth Krause, | Summary: We explore a re-parameterization of the lensing amplitude tension between weak lensing (WL) and cosmic microwave background (CMB) data and its implications for a joint resolution with the Hubble tension. Specifically, we focus on the lensing […]

Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021

Posted by Chicago

Kavli Affiliate: Daniel Holz | First 5 Authors: Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang, B. S. Sathyaprakash, Kirsten Tollefson | Summary: Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probes give access to fundamental physics not […]
