This NAASC Accretion workshop will focus on examining direct observational evidence of the putative process of concentrating the baryon content of the Universe into dark haloes.

The science program was organized to address the following four areas:

(1) the basic physical processes and theoretical expectations from simulations that current and future observations would meaningfully confront;

(2) the latest observations on the reservoirs of baryons in the IGM and CGM at different redshifts, filamentary structure in the IGM, the intra-cluster medium, and the neutral components;

(3) observations of the exchange of gas of all phases between the reservoirs of baryons and galaxies/haloes in the general field, group and cluster environments, and in the larger structure of filaments; and

(4) future observations and possible special purpose instruments or telescopes/missions that could facilitate direct observations of gas accretion onto galaxies and future theoretical studies.
