Can we observe the QCD phase transition-generated gravitational waves through pulsar timing arrays?

This is further made possible by our findings of shallower spectra proportional to the square root of the frequency for nonhelical hydromagnetic turbulence.

Relic gravitational waves from the chiral magnetic effect

no code implementations • 20 Jan 2021 • Axel Brandenburg, Yutong He, Tina Kahniashvili, Matthias Rheinhardt, Jennifer Schober

Here we treat magnetic field generation through the chiral magnetic effect (CME) as a generic mechanism and explore its dependence on the speed of generation (the product of magnetic diffusivity and characteristic wavenumber) and the speed characterizing the maximum magnetic field strength expected from the CME.
