TITLE Special Seminars in the Era of Big Data and A.I. on the Cosmology - Series II
ABSTRACT Title: New technique to trace the magnetic field: gradients
Abstract: I shall introduce a new technique of magnetic field studies that employs the advances of the theory of MHD turbulence and magnetic reconnection. This is the gradient technique that is subdivided into velocity gradients, synchrotron intensity gradients and synchrotron polarization gradients. These techniques provide unique opportunities to explore the 3D structure of magnetic field and also predict the foreground polarization. I shall discuss observational results obtained with the techniques.
