Gravitational Waves from MHD Turbulence and Magnetic Fields in the Early Universe

Explore a 46-minute lecture on gravitational waves generated by magnetohydrodynamic (MHD) turbulence and magnetic fields in the early universe, presented by Alberto Roper Pol at the International Centre for Theoretical Sciences. Learn about the detection of gravitational waves from various cosmological phenomena, including their role in probing physics beyond the Standard Model. Understand how stochastic gravitational wave background signals are generated during inflation, reheating, and preheating processes, as well as from primordial black holes and first-order phase transitions. Discover the significance of recent findings from NANO-Grav, InPTA, and other Pulsar Timing Array collaborations regarding the first evidence of stochastic gravitational wave background detection. Gain insights into how gravitational waves can help explore high-scale physics that may be unreachable through conventional terrestrial or astroparticle physics experiments.
