  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. Deep Chandra observations of a relaxed z = 1.16 galaxy cluster
    Chandra X-ray observations of SPT-CL J2215-3537 resolve the cool core of this z = 1.16 relaxed galaxy cluster, establishing a high-redshift benchmark for cluster evolution studies.
  3. 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.
  4. Milky Way circular velocity measured from stellar abundances
    A new data-driven method measures the Milky Way's circular velocity using element abundance gradients, deriving rotation parameters at the solar radius.
