Modeling the Multiwavelength Detection of Protoclusters. I. An Excess of Submillimeter Galaxies in Protocluster Cores [PDF]
The Astrophysical JournalStudies of galaxy protoclusters yield insights into galaxy cluster formation complementary to those obtained via “archaeological” studies of present-day galaxy clusters.

What are protoclusters? – Defining high-redshift galaxy clusters and protoclusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We explore the structures of protoclusters and their relationship with high redshift clusters using the Millennium Simulation combined with a semi-analytic model. We find that protoclusters are very extended, with 90 per cent of their mass spread across $\sim35\,h^{-1}{\rm Mpc}$ comoving at $z=2$ ($\sim30\, \rm{arcmin}$).

Are Ly α emitters segregated in protoclusters regions? [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The presence of neutral hydrogen in the interstellar medium (ISM) and intergalactic medium (IGM) induces radiative transfer (RT) effects on $\rm {Ly}\,\alpha$ photons that affect the observability of Lyman alpha emitters (LAEs). We use the galform semi-analytic model of galaxy formation and evolution to analyse how these effects

Dusty Galaxies In Protoclusters [PDF]
, 2017 Comparison of Herschel and Planck sources in large area surveys has revealed a pop- ulation of objects that appear to be galaxy clusters or protoclusters, many of whose members are undergoing massive starbursts. Followup studies confirm the likely clus- ter/protocluster nature of these sources.

Discovery of Protoclusters at z ∼ 3.7 and 4.9: Embedded in Primordial Superclusters [PDF]
Astrophysical Journal, 2020 We have carried out follow-up spectroscopy on three overdense regions of g- and r-dropout galaxies in the Canada-France-Hawaii Telescope Legacy Survey Deep Fields, finding two new protoclusters at z = 4.898 and 3.721 and a possible protocluster at z = 3 ...

SCUBA-2 observations of candidate starbursting protoclusters selected by Planck and Herschel-SPIRE [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 We present SCUBA-2 850-μm observations of 13 candidate starbursting protoclusters selected using Planck and Herschel data. The cumulative number counts of the 850-μm sources in 9/13 of these candidate protoclusters show significant overdensities compared

Star formation and chemical enrichment in protoclusters
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We examine star formation and chemical enrichment in protoclusters (PCs) using cosmological zoom-in hydrodynamic simulations. We find that the total star formation rate (SFR) in all PC ($\gt 10^{14.4}\, h^{-1}$ M⊙) reaches $\gt 10^4\, \mathrm{M}_\odot \mathrm{yr}^{-1}$ at z = 3, equivalent to the observed PCs.
