Star formation occurs
when gas cools and collapses under the influence of gravity, but what regulates
the level of star formation, and what stops new stars from forming? There are
many mechanisms that could potentially enhance, regulate and truncate star
formation, and several of these mechanisms (e.g. virial shock heating,
interactions and mergers, ram pressure stripping) should have a dependence on
dark matter halo mass and/or local environment. This thesis measured the
large-scale and small-scale clustering of star forming galaxies to determine
their typical halo masses, trace their evolution, and search for evidence of
star formation being enhanced or truncated by local environment. (...).
