Star formation

  1. NUV-blue spirals show star-forming outer disks
    Study reveals why optically red spiral galaxies show ultraviolet-blue colors: quenched centers with active outer disks sustained by fresh gas accretion or galaxy interactions.
  2. RUBIES confirms many massive quiescent galaxies at 2 < z < 5
    Spectroscopic observations confirm that massive quiescent galaxies were surprisingly common at redshifts 2-5, challenging galaxy formation simulations.
