SUMMARY:The Cosmic Symphony: Magnetic Fields and Turbulence Across Clo
 uds\, Galaxies\, to Galaxy Clusters\, Thesis Defense\, Yue Hu\, Physic
 s Graduate Student
DESCRIPTION:Turbulence and magnetic fields stand at the crossroads of 
 astrophysical and cosmological inquiry\, bridging microscopic physics\
 , such as cosmic rays\, to the large-scale galaxy cluster evolution. D
 espite their paramount importance\, a thorough understanding of their 
 characteristics has remained elusive. In this thesis\, I explore the p
 roperties of magnetohydrodynamic (MHD) turbulence within a partially i
 onized medium through 3D MHD simulations of two-fluids (ions and neutr
 als)\, as well as the influence of stellar feedback. Furthermore\, map
 ping the 3D magnetic field in spatial three dimensions has posed a cen
 tury-long challenge. In this thesis\, based on the anisotropic propert
 ies of MHD turbulence\, I introduce three innovative techniques for tr
 acing the 3D magnetic field: the Velocity Gradient Technique and the u
 se of Convolutional Neural Networks. I will illustrate how these advan
 cements in 3D magnetic field mapping significantly enhance our compreh
 ension of star formation\, Galactic magnetic fields\, the CMB foregrou
 nd polarization\, Seyfert activities in nearby galaxies\, and the evol
 ution of galaxy clusters.
