The Center for Cosmology and AstroParticle Physics (CCAPP) at The Ohio State University (OSU) is holding a mini-workshop on "Assembly Bias and the Galaxy-Halo Relation" in Columbus, Ohio November 24-25, 2014. This workshop will focus on the linked topics of halo and galaxy assembly bias and environmental variations of halo occupation distributions, including impact on cosmological analyses such as galaxy-galaxy lensing and redshift-space distortions.
