Multiobject Spectroscopy of Galaxy Clusters at z ∼ 0.95 in the Ultra Deep Survey Field with Different Star Formation Properties and Large-scale Environments

The Astrophysical Journal Supplement Series
While galaxy clusters are dominated by quiescent galaxies in the local Universe, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts.

The Butcher-Oemler Effect in High Redshift X-ray Selected Clusters [PDF]

, 2001
We are engaged in a wide-field, multi-colour imaging survey of X-ray selected clusters at intermediate and high redshift. We present blue fractions for the first 8 out of 29 clusters, covering almost a factor of 100 in X-ray luminosity.

Enhanced Gas-phase Metallicities and Suppressed Outflows for Galaxies in a Rich Cluster Core at Cosmic Noon

The Astrophysical Journal
We present the results of near-infrared spectroscopy using Keck/MOSFIRE for 23 member galaxies in the X-ray cluster XCS 2215 ( z = 1.46) to investigate the environmental dependence of gaseous flows and metallicities.

Nature of High Equivalent Width Emitters in the Epoch of Reionization Revealed by JWST Medium-band Imaging

The Astrophysical Journal
Extreme emission line galaxies (EELGs) at high redshifts are considered key contributors to cosmic reionization at z  > 6 due to their higher ionization efficiencies.
