Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics
Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33
Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…
Atmosphere mitigation in CMB observations using multi-frequency time-domain component separation
Julien Tang, Shamik Ghosh, Jacques Delabrouille +4
CMB observations from ground-based observatories are limited in sensitivity by the fluctuating emission from the Earth's atmosphere, mostly due to water vapor inhomogeneities. Even…
Unbiased Primordial Gravitational Wave Inference from the CMB with SMICA
Alexander Steier, Shamik Ghosh, Jacques Delabrouille
The detection of primordial gravitational waves in Cosmic Microwave Background B-mode polarization observations requires accurate and robust subtraction of astrophysical contaminat…
Separation of polarized dust emission in Planck observations with Scattering Transforms
Alexandros Tsouros, Elisa Russier, Erwan Allys +3
Polarized dust emission is a major astrophysical foreground contaminant of the cosmic microwave background polarization (CMB), which must be accurately measured to look for the fai…
Full-sky Models of Galactic Microwave Emission and Polarization at Sub-arcminute Scales for the Python Sky Model
Experiment Galactic Science Group, Julian Borrill, Susan E. Clark +15
Polarized foreground emission from the Galaxy is one of the biggest challenges facing current and upcoming cosmic microwave background (CMB) polarization experiments. We develop ne…
Fast far-sidelobe modeling for centimeter to sub-millimeter astrophysical observations
Oliver Jeong, Jacques Delabrouille, Michel Piat
Next-generation centimeter to sub-millimeter telescopes require exquisite control over instrumental far-sidelobe response to accurately measure faint signals like the Cosmic Microw…
