SUMMARY:The Hubble Tension and Primordial Magnetic Fields - Levon Pogosian

DESCRIPTION:The Hubble tension hints at a missing ingredient in the standa
 rd cosmological model describing the universe around the epoch of recombin
 ation. A stochastic magnetic field\, if present in the plasma prior to las
 t scattering\, would induce baryon inhomogeneities and speed up the recomb
 ination process\, reducing the sound horizon at last scattering and potent
 ially helping to relieve the Hubble tension. I will review this proposal a
 nd provide an update on its current status.\n
