Bold new simulations suggest the James Webb Space Telescope might be able to distinguish between competing dark matter models by studying primordial dwarf galaxies
Center for Astrophysics A Hubble image of the colliding galaxies NGC3690. Over its lifetime, a galaxy’s star formation history is affected by many physical processes including mergers. A new study uses many simulations of galaxy evolution to develop a statistical method to categorize the star-formation history from snapshot observations. NASA/ESA/Hubble Galaxies in the observable universe show a remarkable diversity in their structure and properties, mostly because of the many different pathways for their stars to form and evolve. The growth of galaxies typically occurs through the accret...
