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

Protoclusters associated withz> 2 radio galaxies [PDF]
Astronomy & Astrophysics, 2006 [Abridged] We present the results of a large program conducted with the Very Large Telescope and Keck telescope to search for forming clusters of galaxies near powerful radio galaxies at 2.0 < z < 5.2. We obtained narrow- and broad-band images of nine radio galaxies and their surroundings.

The abundance of lensing protoclusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 Weak gravitational lensing provides a potentially powerful method for the detection of clusters. In addition to cluster candidates, a large number of objects with possibly no optical or X-ray component have been detected in shear-selected samples.
