Bar evolution over the last 8 billion years: A constant fraction of strong bars in the gems survey

Abstract:

One-third of present-day spirals host optically visible strong bars that drive their dynamical evolution. However, the fundamental question of how bars evolve over cosmological times has yet to be resolved, and even the frequency of bars at intermediate redshifts remains controversial. We investigate the frequency of bars out to z ∼ 1 drawing on a sample of 1590 galaxies from the Galaxy Evolution from Morphologies and SEDs survey, which provides morphologies from Hubble Space Telescope Advanc...
