Ebook: The IGM/Galaxy Connection: The Distribution of Baryons at z=0

This volume contains the proceedings of the meeting entitled, "The IGM/Galaxy Connection: The Distribution of Baryons at z = 0. " The meeting was held August 8 -10 at the National Center for Atmospheric Research (NCAR) located in Boulder, Colorado on the foothills of the Rocky Mountains (see conference photo). We organized this meeting because we felt it was time to address the link between galaxies and the intergalactic medium at low redshift. In this vein, we posed several questions to the conference participants: Where are the baryons in the local universe and in what phase do they reside? What signatures of galaxy evolution have been imprinted on the IGM? What percentage of intergalactic gas is left from the galaxy formation process? What does the distribution of baryons at z = 0 tell us about the early universe? The conference was an overwhelming success with lots of friendly interaction and discussion among the participants. At lunch we were treated to splendid views from the NCAR terrace and discussions rang­ ing from the importance of the LSR, GSR, and LGSR velocity frames to how long the desserts would last with 90 astronomers and the hot Boul­ der sun. From an inventory of the baryons, to the associations between galaxies and Lya absorbers, to the mechanisms by which galaxies obtain and lose gas, the conference covered many topics. The results of these endeavors are contained in these pages and eloquently summarized by Chris Impey.

This book is a compilation of "The IGM/Galaxy Connection" conference proceedings and begins by examining the census of baryons in the local universe as a function of the states in which they reside (e.g., galaxies, the Lgammaalpha forest, and the hot intra-group gas) and how each of these components evolves with redshift.

Galaxy formation funnels material into galaxies from the IGM through the galactic halo interface, while internal processes in the galaxies feed material back into the IGM. This book characterizes the halos around galaxies, and discusses the relics of the galaxy formation process from a theoretical perspective, followed by observational and theoretical analysis of the feedback mechanisms.

The cosmic web describes the structure of the mass distribution. It consists of a network of filaments that are detected in absorption line studies as the IGM and of groups/clusters of galaxies which form where the filaments intersect. The final section of the book provides an overview of the cosmic web, including the relationship between the IGM and galaxies in the overdense regions of galaxy groups and clusters.

This book is of interest to astronomers and graduate students studying the census of baryons in the local universe, the intergalactic medium, galaxy halos, galaxy formation and evolution, and large scale structure.
