Enriched haloes at redshift $z=2$ with no star-formation: Implications for accretion and wind scenarios

N. Bouche, M. T. Murphy, C. Peroux +9

[Abridged] In order to understand which process (e.g. galactic winds, cold accretion) is responsible for the cool (T~10^4 K) halo gas around galaxies, we embarked on a program to s…
