- W3100507939 abstract "The damping of a non-uniform magnetic field between the redshifts of about $10^4$ and $10^6$ injects energy into the photon-baryon plasma and causes the CMB to deviate from a perfect blackbody spectrum, producing a so-called $mu$-distortion. We can calculate the correlation $langlemu Trangle$ of this distortion with the temperature anisotropy $T$ of the CMB to search for a correlation $langle B^2zetarangle$ between the magnetic field $B$ and the curvature perturbation $zeta$; knowing the $langle B^2zetarangle$ correlation would help us distinguish between different models of magnetogenesis. Since the perturbations which produce the $mu$-distortion will be much smaller scale than the relevant density perturbations, the observation of this correlation is sensitive to the squeezed limit of $langle B^2zetarangle$, which is naturally parameterized by $b_{text{NL}}$ (a parameter defined analogously to $f_{text{NL}}$). We find that a PIXIE-like CMB experiments has a signal to noise $S/Napprox 1.0 times b_{text{NL}} (tilde B_mu/10text{ nG})^2$, where $tilde B_mu$ is the magnetic field's strength on $mu$-distortion scales normalized to today's redshift; thus, a 10 nG field would be detectable with $b_{text{NL}}=mathcal{O}(1)$. However, if the field is of inflationary origin, we generically expect it to be accompanied by a curvature bispectrum $langlezeta^3rangle$ induced by the magnetic field. For sufficiently small magnetic fields, the signal $langle B^2 zetarangle$ will dominate, but for $tilde B_mugtrsim 1$ nG, one would have to consider the specifics of the inflationary magnetogenesis model. We also discuss the potential post-magnetogenesis sources of a $langle B^2zetarangle$ correlation and explain why there will be no contribution from the evolution of the magnetic field in response to the curvature perturbation." @default.
