Quasar Absorption Lines 2 Volume Hardback Set

This two-volume set gives a comprehensive, detailed exposition on the science and analysis of quasar spectra, for both aspiring and seasoned astronomers. Volume 1: 'Introduction, Discoveries, and Methods' introduces the historical development and application of quasar absorption line research, including hydrogen (HI, D/H, 21-cm), HeII, and metal lines from the full range of ions. The connection between absorbers and galaxies, groups, and clusters is treated in depth, as well as the taxonomy and classification of AGN/quasar spectra and their associated absorption lines. Volume 2: 'Astrophysics, Analysis, and Modeling' describes detailed theory and practical methods, including atomic physics of multi-electron ions, radiative transfer in the ΛCDM Universe, principles of spectrograph design, and quantitative analysis of absorption features. It presents the principles of large absorption line surveys for measuring absorber population statistics and the physics of partially ionized gas and multi-component, multiphase chemical-ionization modeling.
