(SHERRY) JCMT-SCUBA2 High Redshift Bright Quasar Survey -- II: the environment of z~6 quasars in sub-millimeter band
Qiong Li, Ran Wang, Xiaohui Fan +14
The formation of the first supermassive black holes is expected to have occurred in some most pronounced matter and galaxy overdensities in the early universe. We have conducted a…
MAMMOTH-Subaru IV. Large Scale Structure and Clustering Analysis of Ly Emitters and Ly Blobs at
Haibin Zhang, Zheng Cai, Mingyu Li +10
We report the large scale structure and clustering analysis of Ly emitters (LAEs) and Ly blobs (LABs) at . Using 3,341 LAEs, 117 LABs, and 58 bright (Ly lumi…
MAMMOTH-Subaru. II. Diverse Populations of Circumgalactic Ly Nebulae at Cosmic Noon
Mingyu Li, Haibin Zhang, Zheng Cai +23
Circumgalactic Lyman-alpha (Ly) nebulae are gaseous halos around galaxies exhibiting luminous extended Ly emission. This work investigates Ly nebulae from deep imaging…
Discovery of optically emitting circumgalactic nebulae around the majority of UV-luminous quasars at intermediate redshift
Sean D. Johnson, Zhuoqi Will Liu, Jennifer I. Li +15
We report the discovery of large ionized, [O II] emitting circumgalactic nebulae around the majority of thirty UV luminous quasars at observed with deep, wide-field int…
The Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing
Yifei Luo, Alexie Leauthaud, Jenny Greene +28
The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…
The Cosmic Ultraviolet Baryon Survey (CUBS) VIII: Group Environment of the Most Luminous Quasars at
Jennifer I. Li, Sean D. Johnson, Erin Boettcher +12
We investigate the group-scale environment of 15 luminous quasars (luminosity erg s) from the Cosmic Ultraviolet Baryon Survey (CUBS) at redshift $z\a…
