The Environments and Evolution of Star Forming Galaxies

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. <br>(...).<br>
