Clustering of galaxies at high redshifts [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
Recent observations show a large concentration of galaxies at high redshift. At first sight, strong clustering of galaxies at high redshifts seems to be in contradiction with the models of structure formation. In this paper we show that such structures are a manifestation of the strong clustering of rare peaks in the density field.

Multivariate Predictors of Lyman Continuum Escape. II. Predicting Lyman Continuum Escape Fractions for High-redshift Galaxies

The Astrophysical Journal
JWST is uncovering the properties of ever-increasing numbers of galaxies at z > 6, during the epoch of reionization. Connecting these observed populations to the process of reionization requires understanding how efficiently they produce Lyman continuum (

MAMMOTH-Subaru. IV. Large Scale Structure and Clustering Analysis of Lyα Emitters and Lyα Blobs at z = 2.2–2.3

The Astrophysical Journal
We report the large scale structure and clustering analysis of Ly α emitters (LAEs) and Ly α blobs (LABs) at z  = 2.2–2.3. Using 3341 LAEs, 117 LABs, and 58 bright (Ly α luminosity L _Ly _α  > 10 ^43.4 erg s ^−1 ) LABs at z  = 2.2–2.3 selected with ...

CHILES. VIII. Probing the Evolution of Average H I Content in Star-forming Galaxies over the Past 5 Gyr

The Astrophysical Journal
Utilizing the COSMOS H I Large Extragalactic Survey (CHILES) data set, we investigate the evolution of the average atomic neutral hydrogen (H I ) properties of galaxies over the continuous redshift range 0.09

Cosmic Magnification of High-Redshift Submillimeter Galaxies

Galaxies
Weak lensing magnification probes the correlation between galaxies and the underlying matter field in a similar fashion to galaxy–galaxy lensing shear. Although it has long been sidelined in favor of the latter on the grounds of poorer performance in terms of statistical significance, the provision of a large sample of high-redshift submillimeter ...

PRUSSIC

Astronomy & Astrophysics
Characterising the relationship between dense gas and star formation is critical for understanding the assembly of galaxies throughout cosmic history. However, due to the faintness of standard dense-gas tracers – HCN, HCO+, and HNC – dense gas in high ...

JWST NIRSpec Spectroscopy of the Remarkable Bright Galaxy GHZ2/GLASS-z12 at Redshift 12.34

The Astrophysical Journal
We spectroscopically confirm the M _UV = −20.5 mag galaxy GHZ2/GLASS-z12 to be at redshift z = 12.34. The source was selected via NIRCam photometry in GLASS-JWST Early Release Science data, providing the first evidence of a surprising abundance of bright
