Title: Characterizing low-redshift Lyman-alpha blobs

Abstract: Lyman-alpha blobs (LABs) are landmarks of massive galaxy formation that, until recently, have only been known at high redshift. We have identified LABs at z=0.3, where they are much easier to study than their high redshift counterparts. This proposal is part of a large multiwavelength campaign to understand the physical conditions in LABs, their ionization histories, formation, and evolution with redshift. We will also study the Lyman-alpha escape mechanism. Our project includes data from Chandra, NUSTAR, GALEX, HST, Gemini, and PanSTARRS. We ask Gemini for a substantial amount of time in fairly modest to poor observing conditions. The coordinates for the targets selected from the PanSTARRS survey will be known by December 2016.
