cds-question@unistra.frgalaxy-clustersredshiftedvisible-astronomyspectroscopyWhile galaxy clusters are dominated by quiescent galaxies in the local Universe, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here we present the discovery of two galaxy clusters at z~0.95 with contrasting QFs despite having similar masses (log(M_200_/M_{sun}_)~14) and spectra and redshifts of 29 galaxies in these clusters and 76 galaxies in the surrounding area. The clusters are found in the Ultra Deep Survey field and confirmed through multiobject spectroscopic observation using the Inamori Magellan Areal Camera and Spectrograph on the Magellan telescope. The two clusters exhibit QFs of 0.094_-0.032_^+0.11^ and 0.38_-0.11_^+0.14^, respectively. Analysis of large-scale structures (LSSs) surrounding these clusters finds that properties of these clusters are consistent with the anticorrelation trend between the QF and the extent of surrounding LSS, found in Lee+ 2019, J/MNRAS/490/135, which can be interpreted as a result of the replenishment of young, star-forming galaxies keeping the QF low when galaxy clusters are accompanied by rich surrounding environments.2024ApJS..272...47Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/272/47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)J/A+A/345/419 : Star formation in early-type galaxies (Longhetti+ 1999)J/ApJS/176/1 : Subaru/XMM-Newton deep survey (SXDS).
