Obtaining the Strength of the Magnetic Field from E- and B-Modes of Dust Polarization
We perform numerical simulations of supersonic magnetohydrodynamic (MHD) turbulence and calculate Fourier power spectra of E - and B -modes arising from dust polarization. We pay close attention to the ratio of E -mode to B -mode spectra (a.k.a. E/B power asymmetry) on small spatial scales. We find...
