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…
The scalar, vector, and tensor modes in gravitational wave turbulence simulations
Axel Brandenburg, Grigol Gogoberidze, Tina Kahniashvili +3
We study the gravitational wave (GW) signal sourced by primordial turbulence that is assumed to be present at cosmological phase transitions like the electroweak and quantum chromo…
Circular Polarization of Gravitational Waves from Early-Universe Helical Turbulence
Tina Kahniashvili, Axel Brandenburg, Grigol Gogoberidze +2
We perform direct numerical simulations to compute the net circular polarization of gravitational waves from helical (chiral) turbulent sources in the early Universe for a variety…
Primordial magnetic helicity evolution with a homogeneous magnetic field from inflation
Axel Brandenburg, Ruth Durrer, Yiwen Huang +3
Motivated by a scenario of magnetogenesis in which a homogeneous magnetic field is generated during inflation, we study the magnetohydrodynamic evolution of the primordial plasma m…
Magnetism in the Early Universe
Tina Kahniashvili, Axel Brandenburg, Arthur Kosowsky +2
Blazar observations point toward the possible presence of magnetic fields over intergalactic scales of the order of up to Mpc, with strengths of at least G…
E and B polarizations from inhomogeneous and solar surface turbulence
Axel Brandenburg, Andrea Bracco, Tina Kahniashvili +4
Gradient- and curl-type or E- and B-type polarizations have been routinely analyzed to study the physics contributing to the cosmic microwave background polarization and galactic f…
