The baryon cycle in galaxy halos is the result of an interplay between AGN\/stellar outflows and inflows from the intergalactic medium. Observational constraints on the gas properties provide a clue for cosmological simulations and shed light on feedback mechanisms. Due to the complex multiphase nature of the gas, understanding feedback processes requires a comprehensive study of the gas in the hot ionized as well as warm and cold neutral phases. Unfortunately, in contrast with cold and ionized gas, estimation of the temperature of the warm phase is a difficult task. This can be overcome using the analysis of absorption lines imprinted onto quasar spectra.\u00a0 We present such measurements of the warm neutral gas temperature, based on the state-of-the-art VLT\/UVES observations. We show that the warm neutral gas exhibits a huge variety of estimated temperatures, which in some cases even exceed the canonical Galactic value.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"categorias_charlas":[59],"class_list":["post-2231","charlas","type-charlas","status-publish","hentry","categorias_charlas-seminarios"],"acf":[],"yoast_head":"\nHow warm is the gas around high-redshift galaxies?
