QUASAR ABSORPTION LINES
Volume 2 Lectures
Embedded Files
Volume 2 treats the theory and analysis of absorption lines, including the physics of atomic transitions, gas and ionization physics, the cosmological model, radiative transfer, spectrograph design, analysis of spectra, and multi-component, multiphase chemical-ionization modeling. Pragmatic approaches to conducting and assessing absorber counts in large absorption line surveys is presented. Throughout, objective analysis methods are emphasized and presented for clarity of practical application.
A Note to Students/Learners
The lecture slides provide abridged versions of the chapter content. They are designed to be useful as personal study guides and supplements to the book chapters. Think of them as the TL;DR for each chapter.
A Note to Instructors
The lecture slides should be suitable for 30-45 minute lectures. Each focuses on the main takeaways from each chapter, skipping the larger portion of the derivations and minor points.
