The cold circumgalactic environment of MAMMOTH-I: dynamically cold gas in the core of an Enormous Ly-alpha Nebula
Bjorn Emonts, Zheng Cai, Xavier Prochaska +2
The MAMMOTH-I Nebula at redshift 2.3 is one of the largest known Ly-alpha nebulae in the Universe, spanning ~440 kpc. Enormous Ly-alpha nebulae like MAMMOTH-I typically trace the d…
Nearly all Massive Quiescent Disk Galaxies have a Surprisingly Large Atomic Gas Reservoir
Chengpeng Zhang, Yingjie Peng, Luis C. Ho +11
The massive galaxy population above the characteristic Schechter mass M*~10^10.6 Msun contributes to about half of the total stellar mass in the local Universe. These massive galax…
Evolution of the Cool Gas in the Circumgalactic Medium (CGM) of Massive Halos -- A Keck Cosmic Web Imager (KCWI) Survey of Ly Emission around QSOs at
Zheng Cai, Sebastiano Cantalupo, J. Xavier Prochaska +6
Motivated by the recent discovery of the near-ubiquity of Ly emission around QSOs, we performed a systematic study of QSO circumgalactic Ly emission at $z\appro…
Discovery of a Lya emitting dark-cloud within z ~ 2.8 SMMJ02399-0136 system
Qiong Li, Zheng Cai, J. Xavier Prochaska +9
We present Keck/KCWI integral field spectrograph observations of the complex system surrounding SMM J023990136 (a lensed sub-mm galaxy), including an associated Ly$\rm α…
