Undergraduate Bursary: Star Formation Quenching Efficiency in Filaments of Galaxies
People Involved
Project Description
Galaxy evolution is typically studied in discrete environments – usually within galaxy clusters or groups where the galaxy-galaxy interaction rate is high, in voids where the galaxies are largely unaffected by others of their ilk, or within the context of a very large observational survey or simulation. However, this misses the environment of filaments of galaxies as a discrete large-scale environment themselves. Informed by our recent work (Kleiner, Pimbblet et al. 2017), we suggest that galaxy filaments are the primary location where galaxies start to become quenched in their star formation rates for the first time. The proposed student will use the formalism of Balogh et al. (2016) to determine f_convert – the fraction of galaxies that have been prematurely quenched due to their environment – inside filaments for the first time. This will use existing survey data from the GAMA survey and complementary data from the Illustris survey to determine f_convert and will ultimately aim to compute the time between first accretions into a massive halo and when star formation is fully quenched.
