"Intergalactic Magnetic Field Observations and their Fundamental Implications"

Speaker:  Tanmay Vachaspati (Arizona State University)


I will review current observational evidence for helical intergalactic magnetic fields at the ~10-14 G level on ~10 Mpc length scales. The existence of magnetic fields in cosmic voids and their non-trivial helical structure suggest that they might have originated in the early universe due to CP violating fundamental interactions. The large helicity of the magnetic field suggests a possible crucial role for chiral MHD effects in the early universe.
