Cosmic Himalayas: The Highest Quasar Density Peak Identified in a 10,000 deg2 Sky with Spatial Discrepancies between Galaxies, Quasars, and IGM H i

The Astrophysical Journal
We report the identification of a quasar overdensity in the BOSSJ0210 field, dubbed the Cosmic Himalayas, consisting of 11 quasars at z = 2.16−2.20, the densest overdensity of quasars (17 σ ) in the ∼10,000 deg ^2 of the Sloan Digital Sky Survey (SDSS ...

MUSEQuBES: Connecting H i Absorption with Lyα Emitters at z ≈ 3.3

The Astrophysical Journal
We present a comprehensive analysis of H i absorption around 96 Ly α emitters (LAEs) at z  ≈ 3.3 (median Ly α luminosity ≈10 ^42 erg s ^−1 ). These LAEs were identified within eight MUSE fields, each $1^{\prime} \times 1^{\prime} $ on the sky and ...

ODIN: Star Formation Histories Reveal Formative Starbursts Experienced by Lyα-emitting Galaxies at Cosmic Noon

The Astrophysical Journal Letters
In this work, we test the frequent assumption that Ly α -emitting galaxies (LAEs) are experiencing their first major burst of star formation at the time of observation.

Quantifying the Escape of Lyα at z ≈ 5–6: A Census of Lyα Escape Fraction with Hα-emitting Galaxies Spectroscopically Confirmed by JWST and VLT/MUSE

The Astrophysical Journal Supplement Series
The James Webb Space Telescope provides an unprecedented opportunity for unbiased surveys of H α -emitting galaxies at z > 4 with the NIRCam's wide-field slitless spectroscopy (WFSS).

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs)

Astronomy & Astrophysics
We report on Chandra X-ray observations of four narrow-line quasar candidates at z ∼ 6, selected from the Subaru high-z exploration of low-luminosity quasars (SHELLQs) project, based on the Subaru Hyper Suprime-Cam survey. These objects are characterised

The One-hundred-deg2 DECam Imaging in Narrowbands (ODIN): Survey Design and Science Goals

The Astrophysical Journal
We describe the survey design and science goals for One-hundred-deg ^2 DECam Imaging in Narrowbands (ODIN), a NOIRLab survey using the Dark Energy Camera (DECam) to obtain deep (AB ∼ 25.7) narrowband images over an unprecedented area of sky.

Identifying a Protocluster Formation at z ∼ 4.5 in the COSMOS Field: An Extension of the Taralay Protocluster, Traced by Lyα Emitters Surrounding a Submillimeter Galaxy

The Astrophysical Journal
We report the discovery of a large-scale structure containing multiple overdensities at z = 4.54 ± 0.03 in the COSMOS field, with the most prominent one likely infalling toward the recently identified Taralay protocluster.
