Probing the effect of the protocluster environment on galaxy morphology at z = 2.23
Astronomy & AstrophysicsContext. As galaxies evolve in dense cluster and protocluster environments, they interact and quench their star formation. This gradually transforms the dominant galaxy population from star-forming galaxies to quiescent red galaxies.

Building blocks of the universe:The search for galaxy protoclusters [PDF]
, 2023 Galaxy clusters are the most massive virialized structures in the presentday Universe, containing thousands of galaxies. Since the dawn of the concept of galaxies, astronomers have been studying the distribution of galaxies across the sky and found them ...

Characterizing Protoclusters and Protogroups at z $\sim$ 2.5 Using Ly$\alpha$ Tomography [PDF]
, 2022 Ly-$\alpha$ tomography surveys have begun to produce three-dimensional (3D) maps of the intergalactic medium (IGM) opacity at $z \sim 2.5$ with Mpc resolution.

A massive protocluster of galaxies at a redshift of z ≈ 5.3 [PDF]
Nature, 2011 Massive clusters of galaxies have been found that date from as early as 3.9 billion years1 (3.9 Gyr; z = 1.62) after the Big Bang, containing stars that formed at even earlier epochs2, 3. Cosmological simulations using the current cold dark matter model predict that these systems should descend from ‘protoclusters’—early overdensities of massive ...

The Young and the Wild: What happens to Protoclusters forming at z = 4? [PDF]
, 2022 Using one of the largest volumes of the hydrodynamical cosmological simulation suit Magneticum, we study the evolution of protoclusters identified at redshift = 4, with properties similar to SPT2349-56.

Narrowband Imaging of a z = 3.24 Protocluster: Insights from [O iii]-emitting Galaxies
The Astrophysical JournalWe present narrowband imaging of a spectroscopically confirmed protocluster “D4UD01” at z = 3.24 using CFHT/WIRCam. We identify a sample of 24 [O iii ] emission-line galaxies in the field, which forms a large overdensity in the protocluster region.

THECHANDRADEEP PROTOCLUSTER SURVEY: EVIDENCE FOR AN ENHANCEMENT OF AGN ACTIVITY IN THE SSA22 PROTOCLUSTER ATz= 3.09 [PDF]
The Astrophysical Journal, 2009 We present results from a new ultra-deep 400 ks Chandra observation of the SSA22 protocluster at z = 3.09. We have studied the X-ray properties of 234 z ~ 3 Lyman break galaxies (LBGs; protocluster and field) and 158 z = 3.09 Ly-alpha emitters (LAEs) in SSA22 to measure the influence of the high-density protocluster environment on the accretion ...

How well do submillimeter galaxies trace protoclusters? [PDF]
, 2017 It has been suggested that associations of (or even individual) high-redshift submillimeter galaxies (SMGs) may serve as beacons of protoclusters because SMGs are high-mass galaxies undergoing rapid assembly.
