Extragalactic Gas at Low Redshift

Résumé

Annotation Proceedings of an April 2002 workshop held at the Carnegie Observatories in Pasadena, California, bringing together some 70 international specialists to discuss low redshift QSO absorbers and their relationship to galaxies. Forty-two contributions are arranged in sections on low- absorber properties and absorber-galaxy relationships, simulations, HI studies, high velocity clouds, galactic winds, the intergalactic medium, the ionizing background radiation, and astronomical tools. A sampling of topics: the evolution of neutral gas in the universe as traced by damped Lyman alpha systems, surveying the whole sky for extragalactic neutral hydrogen, mapping metal-enriched high velocity clouds to very low HI column densities, galactic superwinds circa 2001, and using X-ray shadowing to detect intergalactic baryons.
