Interstellar Magnetic Fields

Mehr zum Buch

This comprehensive work explores the intricate role of large-scale magnetic fields across various cosmic structures, focusing on galaxies, the Milky Way, star-forming regions, supernova remnants, and accretion disks. It begins with an examination of interstellar magnetic fields, including their historical context and future implications, alongside dynamo processes that generate these fields on a grand scale. The text delves into specific galaxies, analyzing the structure and dynamics of magnetic fields in spiral galaxies and dwarf galaxies, with detailed observations of M31, IC 342, M33, and NGC 6946. The discussion extends to the Milky Way, highlighting the local magnetic field's characteristics and its impact on galactic dynamics, including the formation of galactic winds and the influence of hidden matter. The book also addresses the significance of magnetic fields in star formation, presenting studies on their effects in newly formed stars and supernova remnants. In the latter sections, the focus shifts to magnetic fields in accretion disks and jets, exploring their interactions with black holes and the dynamics of gas flows. Theoretical aspects related to cosmic magnetic fields are also covered, including magnetostatic equilibria and particle acceleration at shock waves. This work serves as a vital resource for understanding the complex interplay between magnetic fields and various astrophysical phenomena.
