Multi-Object Spectroscopy of Galaxy Clusters at in Ultra Deep Survey Field with Different Star-formation Properties and Large-scale Environments
Seong-Kook Lee, Myungshin Im, Bomi Park +3
While galaxy clusters are dominated by quiescent galaxies at local, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here, we present the discovery of…

High- Universe probed via Lensing by QSOs (HULQ) II. Deep GMOS spectroscopy of a QSO lens candidate
Yoon Chan Taak, Myungshin Im, Yongjung Kim +2
Galaxies and their central supermassive black holes are known to coevolve, but the physical background for this is unknown as of yet. The High- Universe probed via Lensing by QS…
