Large-Scale Structure of Galaxies Traced by the WISE Mission

Details of Project
- The WISE satellite pre-launch, with Prof. Blain in the foreground. This was in May 2009, a few days after the telescope was mated to the spacecraft bus. The true scale of the spacecraft is about twice what it appears next to the supervisor. <br />

The way in which galaxies are distributed in space provides a direct way to see the nature of the density fluctuations that seeded galaxy formation, by way of their final products. By combining large samples of galaxy redshifts with the excellent pictures of the mass of galaxies produced by the all-sky infrared survey made by NASA's WISE mission, the student will move to highlight the most interesting large-scale structures in the low-to-moderate redshift Universe, taking advantage of WISE's access over the whole sky, extending closer to the galactic plane, and to a higher redshift than other surveys. The intention is to provide a guide to the distribution of the mass and stars in galaxies as a function of their environment and to better constrain the science that can be done with future missions like DES, LSST, GAIA, EUCLID and WFIRST.
