A Multiwavelength Study of ELAN Environments (AMUSE): Ubiquitous dusty star-forming galaxies associated with enormous Ly nebulae on megaparsec scales
Marta Nowotka, Chian-Chou Chen, Fabrizio Arrigoni Battaia +5
We have been undertaking a systematic survey at 850 m based on a sample of four prototypical enormous Ly nebulae (ELANe) as well as their megaparsec-scale (Mpc-sca…
Massive molecular outflow and 100 kpc extended cold halo gas in the enormous Ly nebula of QSO 1228+3128
Jianrui Li, Bjorn H. C. Emonts, Zheng Cai +9
The link between the circum-galactic medium (CGM) and the stellar growth of massive galaxies at high- depends on the properties of the widespread cold molecular gas. As part of…
Discovery of a protocluster core associated with an enormous Ly Nebula at
Qiong Li, Ran Wang, Helmut Dannerbauer +10
The MAMMOTH-1 nebula at is an enormous Ly nebula (ELAN) extending to a 440 kpc scale at the center of the extreme galaxy overdensity BOSS 1441. In this paper, we…
A [C II] 158m Emitter Associated with an OI Absorber at the End of the Reionization Epoch
Yunjing Wu, Zheng Cai, Marcel Neeleman +12
The physical and chemical properties of the circumgalactic medium (CGM) at have been studied successfully through the absorption in the spectra of background Quasi-Stel…
From large-scale environment to CGM angular momentum to star forming activities -- II: quenched galaxies
Shengdong Lu, Dandan Xu, Sen Wang +7
The gas needed to sustain star formation in galaxies is supplied by the circumgalactic medium (CGM), which in turn is affected by accretion from large scales. In a series of two pa…
Spectroscopic Confirmation of two Extremely Massive Protoclusters BOSS1244 and BOSS1542 at
Dongdong Shi, Zheng Cai, Xiaohui Fan +3
We present spectroscopic confirmation of two new massive galaxy protoclusters at , BOSS1244 and BOSS1542, traced by groups of Coherently Strong Ly Absorption (CoS…
More variable quasars have stronger emission lines
Wen-Yong Kang, Jun-Xian Wang, Zhen-Yi Cai +1
The UV/optical variation, likely driven by accretion disc turbulence, is a defining characteristic of type 1 active galactic nuclei (AGNs) and quasars. In this work we investigate…
Accelerated galaxy growth and environmental quenching in a protocluster at z=3.24
Ke Shi, Jun Toshikawa, Kyoung-Soo Lee +3
We present a multiwavelength study of galaxies around D4UD01, a spectroscopically confirmed protocluster at z = 3.24 to investigate environmental trends. 450 galaxies are selected…
"A more probable explanation" is still impossible to explain GN-z11-flash: in response to Steinhardt et al. (arXiv:2101.12738)
Linhua Jiang, Shu Wang, Bing Zhang +8
In Jiang et al. (2020), we reported a possible bright flash (hereafter GN-z11-flash) from a galaxy GN-z11 at z ~ 11. Recently, Steinhardt et al. (2021; arXiv:2101.12738) found 27 i…
Improved Lyman Alpha Tomography using Optimized Reconstruction with Constraints on Absorption (ORCA)
Zihao Li, Benjamin Horowitz, Zheng Cai
In this work, we propose an improved approach to reconstruct the three-dimensional intergalactic medium from observed Lyman- forest absorption features. We present our new metho…
