Snowmass2021 Cosmic Frontier: Cosmic Microwave Background Measurements White Paper
Clarence L. Chang, Kevin M. Huffenberger, Bradford A. Benson +128
This is a solicited whitepaper for the Snowmass 2021 community planning exercise. The paper focuses on measurements and science with the Cosmic Microwave Background (CMB). The CMB…
Snowmass2021 CMB-HD White Paper
HD Collaboration, Simone Aiola, Yashar Akrami +61
CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep (0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a survey w…
Axion Condensate Dark Matter Constraints from Resonant Enhancement of Background Radiation
Günter Sigl, Pranjal Trivedi
We investigate the possible parametric growth of photon amplitudes in a background of axion-like particle (ALP) dark matter. The observed extragalactic background radiation limits…
Axion-like Dark Matter Constraints from CMB Birefringence
Günter Sigl, Pranjal Trivedi
Axion-like particles are dark matter candidates motivated by the Peccei-Quinn mechanism and also occur in effective field theories where their masses and photon couplings are indep…
Magnetic heating across the cosmological recombination era: Results from 3D MHD simulations
Pranjal Trivedi, Johannes Reppin, Jens Chluba +1
The origin of cosmic magnetic fields is an unsolved problem and magnetogenesis could have occurred in the early Universe. We study the evolution of such primordial magnetic fields…
Primordial Magnetic Field Limits from CMB Trispectrum - Scalar Modes and Planck Constraints
Pranjal Trivedi, Kandaswamy Subramanian, T. R. Seshadri
Cosmic magnetic fields are observed to be coherent on large scales and could have a primordial origin. Non-Gaussian signals in the cosmic microwave background (CMB) are generated b…
Cosmic Microwave Background Trispectrum and Primordial Magnetic Field Limits
Pranjal Trivedi, T. R. Seshadri, Kandaswamy Subramanian
Primordial magnetic fields will generate non-Gaussian signals in the cosmic microwave background (CMB) as magnetic stresses and the temperature anisotropy they induce depend quadra…
Primordial Magnetic Field Limits from Cosmic Microwave Background Bispectrum of Magnetic Passive Scalar Modes
Pranjal Trivedi, Kandaswamy Subramanian, T. R. Seshadri
Primordial magnetic fields lead to non-Gaussian signals in the cosmic microwave background (CMB) even at the lowest order, as magnetic stresses and the temperature anisotropy they…
