Unbiased galaxy and CGM investigation with MUSE deep archival survey
Currently, MUSE has observed about 150 square arcmin sky areas with more than 4-hour exposure in good conditions. Without any pre-selection, we can obtain an emission-line galaxy catalogue in the deep field. Following by searching for absorption lines from intervening emission-line object, we can have a dataset of emission-absorption pairs without pre-selecting background quasars or galaxies, which can help to map out the CGM for a variety of galaxies in an unbiased way. The 3D nature of MUSE can also help us to investigate the CGM in a more spatially-extended way that we are not restricted to a single pencil beam from the background quasar. In addition, the emission-absorption pairs can help us to study the same galaxies both from emission and absorption perspectives, which can help a lot in understanding the galaxy evolution.
