July 2015: MSU astronomer on research team re-evaluating population of early galaxies

  • Jul 1, 2015

 

In this July 1st, 2015 article in MSU Today, research by a group including MSU P-A Associate Professor Brian O'Shea is described. Using computer modeling of galaxy formation, the group is predicting a smaller number of faint galaxies in the very early universe than earlier models had suggested. These predictions will be tested in studies by the James Webb Space Telescope (scheduled for late 2018), as the Hubble Space Telescope is sensitive only to the brighter end of the range of early galaxies, where there is less of a difference between the new and old models.
