The clustering properties of high-redshift passive galaxies

Monthly Notices of the Royal Astronomical Society: Letters, 2023
ABSTRACT We investigate the clustering properties of 3 < z < 5 candidate passive galaxies from the Merlin et al. (2019) sample residing in the GOODS-North (35 sources) and GOODS-South (33 sources) fields. Within the large uncertainties due to the paucity of sources we do not detect clustering signal in GOODS-North, while ...

The Evolution of Galaxies in and around Clusters at High-Redshift [PDF]

Publications of the Astronomical Society of Japan, 2004
Abstract In this paper, we focus on ram-pressure stripping and evaporation of disk galaxies in and around a cluster. We show that the evolution of the disk surface density affects the efficiency of ram-pressure stripping of galaxies at $z\gtrsim 1$.

Galaxy and mass assembly (GAMA) : AUTOZ spectral redshift measurements, confidence and errors [PDF]

, 2014
The Galaxy And Mass Assembly (GAMA) survey has obtained spectra of over 230 000 targets using the Anglo-Australian Telescope. To homogenize the redshift measurements and improve the reliability, a fully automatic redshift code was developed (AUTOZ).

A Gradual Decline of Star Formation since Cluster Infall: New Kinematic Insights into Environmental Quenching at 0.3 < z < 1.1

The Astrophysical Journal, 2023
The environments where galaxies reside crucially shape their star formation histories. We investigate a large sample of 1626 cluster galaxies located within 105 galaxy clusters spanning a large range in redshift (0.26 < z < 1.13). The galaxy clusters are

Hawaii Two-0: high-redshift galaxy clustering and bias [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We perform an analysis of two-point galaxy clustering and galaxy bias using Subaru Hyper-Suprime Cam (HSC) data taken jointly by the Subaru Strategic Program and the University of Hawaii in the Cosmic Evolution Survey (COSMOS) field over an area of 1.8 sq deg.

The SRG/eROSITA All-Sky Survey

Astronomy & Astrophysics
We selected galaxy cluster candidates from the high-redshift (BEST_Z > 0.9) end of the first SRG (Spectrum Roentgen Gamma)/eROSITA All-Sky Survey (eRASS1) galaxy cluster catalogue, for which we obtained moderately deep J-band imaging data with the ...

Studying Cosmic Evolution with the XMM-Newton Distant Cluster Project [PDF]

, 2007
Investigating X-ray luminous galaxy clusters at high redshift (z>~1) provides a challenging but fundamental constraint on evolutionary studies of the largest virialized structures in the Universe, the baryonic matter component in form of the hot ...

A Large-scale Kinematic Study of Molecular Gas in High-z Cluster Galaxies: Evidence for High Levels of Kinematic Asymmetry

The Astrophysical Journal, 2023
We investigate the resolved kinematics of the molecular gas, as traced by the Atacama Large Millimeter/submillimeter Array in CO (2−1), of 25 cluster member galaxies across three different clusters at a redshift of z ∼ 1.6.
