Redshift

  1. Cluster stellar mass growth is mostly established by redshift 0.8
  2. Higher-order statistics improve constraints on reionization history
  3. Non-Gaussian redshift-space Minkowski tensors show qualified perturbation-theory success
  4. Two radio shells likely trace galaxy merger shocks
  5. 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.
  6. Supermassive stars may match JWST little red dot spectra
    Supermassive star models reproduce spectral signatures of JWST little red dots, suggesting these compact sources may be progenitors of the first supermassive black holes.
