Specifically, we searched for the H-alpha line emission from galaxies near very strong z=2 MgII absorbers (with rest-frame equivalent width EW>2 \\AA) because these could be the sign-posts of outflows or inflows. Surprisingly, we detect H-alpha from only 4 hosts out of 20 sight-lines (and 2 out of the 19 HI-se","authors_text":"2), (2) IRAP Toulouse, (3), (4) OAMP, (5) MPE), C. L. Martin (1), C. Peroux (4), D.
