Receipt: # 203-2 ----- Attempting Submission 3 (Fri Apr 10 14:58:09 GMT 2015) ----- We propose to run a series of zoom renormalization simulations of group-sized halos using the EAGLE (Evolution and Assembly of GaLaxies and their Environments) code integrated with our non-equilibrium module to follow the time-dependent ionization and cooling of individual ionic species observed by the Cosmic Origins Spectrograph (COS). Starting with a suite of zooms that reproduce important properties of galaxies and the circumgalactic medium, we aim to extend the zooms to the group scale by resimulating halos Mvir=10^12.7-10^14.0 Msol. We will focus on the physical properties of the intra-group medium (IGrM) that can be constrained via COS absorption line measurements that find OVI, HI (narrow and broad), and other metal lines at sight lines impacting between 0-2 Rvir The science goals of our simulation-observation confrontation are two-fold: 1) to understand the role of the IGrM in transforming and quenching galaxies, and 2) to find a new handle on the baryon content and distribution in and around groups. The first goal emphasizes the importance of the group environment in galaxy formation in the highly clustered evolved Universe. The second goal is important in the 'era of precision cosmology' where dark energy surveys require accurate modeling the effects of galactic feedback on the baryon distribution.
