Available in PDF, EPUB and Kindle. Book excerpt: To understand the formation and evolution of galaxies, it is essential to understand the gas that exists in the vicinity of galaxies. Mg II absorption systems probe the circumgalactic medium (CGM) around galaxies and can provide hints to the nature of the gas. To fully understand the complex structure of the CGM, it is necessary to investigate not only low-ionization transitions such as those of Mg II, but also transition lines associated with more diffuse high-ionization material.We report our analysis of six intervening quasar absorption line systems, which probe the CGM at redshifts 0.4
