Series: JSI Colloquium
Date: Monday 03-October-2016
Time: 15:00-16:00 (3:00-4:00 pm)
Location: PSC 1136
Speaker: Dr. Tanmay Vachaspati (Arizona State University)
Title: "Intergalactic Magnetic Field Observations and their Fundamental Implications"

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.
