LiteBIRD science goals and forecasts: primordial magnetic fields

D Paoletti, JA Rubino-Martin, M Shiraishi… - … of Cosmology and …, 2024 - iopscience.iop.org
We present detailed forecasts for the constraints on the characteristics of primordial
magnetic fields (PMFs) generated prior to recombination that will be obtained with the …

Magnetohydrodynamics of chiral relativistic fluids

A Boyarsky, J Fröhlich, O Ruchayskiy - Physical Review D, 2015 - APS
We study the dynamics of a plasma of charged relativistic fermions at very high temperature
T≫ m, where m is the fermion mass, coupled to the electromagnetic field. In particular, we …

Constraining primordial magnetic fields with line-intensity mapping

T Adi, S Libanore, HAG Cruz… - Journal of Cosmology …, 2023 - iopscience.iop.org
Primordial magnetic fields (PMFs) offer a compelling explanation for the origin of observed
magnetic fields, especially on extragalactic scales. Such PMFs give rise to excess of power …

Inflationary magnetogenesis with reheating phase from higher curvature coupling

K Bamba, E Elizalde, SD Odintsov… - Journal of Cosmology …, 2021 - iopscience.iop.org
We investigate the generation of magnetic fields from inflation, which occurs via breakdown
of the conformal invariance of the electromagnetic (EM) field, when coupled with the Ricci …

Di-lepton production from a single photon in strong magnetic fields: vacuum dichroism

K Hattori, H Taya, S Yoshida - Journal of High Energy Physics, 2021 - Springer
A bstract We study di-lepton production from a single photon in the presence of a strong
constant magnetic field. By the use of the Ritus-basis formalism, we analytically evaluate the …

Effective theory of inflationary magnetogenesis and constraints on reheating

D Maity, S Pal, T Paul - Journal of Cosmology and Astroparticle …, 2021 - iopscience.iop.org
Effective theory framework based on symmetry has recently gained widespread interest in
the field of cosmology. In this paper, we apply the same idea on the genesis of the primordial …

Cross-correlations between scalar perturbations and magnetic fields in bouncing universes

D Chowdhury, L Sriramkumar… - Journal of Cosmology …, 2019 - iopscience.iop.org
Bouncing scenarios offer an alternative to the inflationary paradigm for the generation of
perturbations in the early universe. Recently, there has been a surge in interest in examining …

Magnetogenesis from axion-SU (2) inflation

A Brandenburg, O Iarygina… - Journal of Cosmology …, 2024 - iopscience.iop.org
We describe a novel proposal for inflationary magnetogenesis by identifying the non-
Abelian sector of Spectator Chromo Natural Inflation (SCNI) with the SU (2) L sector of the …

Magnetogenesis by non-minimal coupling to gravity in the Starobinsky inflationary model

O Savchenko, Y Shtanov - Journal of Cosmology and …, 2018 - iopscience.iop.org
The R 2 term in the Starobinsky inflationary model can be regarded as a leading quantum
correction to the gravitational effective action. We assume that parity-preserving and parity …

The electric charge of black holes within galaxies

ND Padilla, IJ Araya, F Stasyszyn - Journal of Cosmology and …, 2024 - iopscience.iop.org
We present improved estimates of the electric charge that black holes could hold when
these are embedded in the ionised plasma within galaxies. We have implemented the …
