Extragalactic astronomy. Book 2. Galaxies: multiwavelength properties

Abstract

This textbook follows the «Extragalactic Astronomy. Book 1. Galaxies: basic physical properties». Book 2 describes methods and instrumental means for obtaining and processing data on physical properties of galaxies in various spectral ranges. Attention is paid to galaxies with excess radiation in the IR, radio, UV, and X- bands, to the dwarf galaxies, peculiar and interacting galaxies, and galaxies with active nuclei. To understand the physical processes that take place in these large-scale structures of the Universe, the distributions of energy and density of matter in galaxies are considered, including the dark matter density profiles, the dynamics and kinematics of stars, the main statements of density wave theory, gravitational lensing, the effects of the general theory of relativity, models of accretion into supermassive black holes, interstellar medium in galaxies (gas and dust components, magnetic field, cosmic rays). For students, postgraduates, and lecturers in the specialty “Physics and Astronomy”.
