SCUBA-2 overdensities associated with candidate protoclusters selected from Planck data [PDF]
, 2020 We measure the 850-μm source densities of 46 candidate protoclusters selected from the Planck High-z catalogue (PHz) and the Planck Catalogue of Compact Sources (PCCS) that were followed up with Herschel -SPIRE and SCUBA-2.

The internal structure of protoclusters and the formation of galaxies [PDF]
Symposium - International Astronomical Union, 1978 We give a short review of the general picture and main features of the formation of galaxies and clusters of galaxies on the basis of the adiabatic theory. Detailed discussions of these questions are published in references 1–6. Some related problems of the formation and development of large scale structure in the Universe according to the same theory ...

SPECTROSCOPIC CONFIRMATION OF A PROTOCLUSTER AT z ≈ 3.786 [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present new observations of the field containing the z = 3.786 protocluster PC 217.96+32.3. We confirm that it is one of the largest known and most overdense high-redshift structures. Such structures are rare even in the largest cosmological simulations. We used the Mayall/MOSAIC1.1 imaging camera to image a 1.°2 × 0.°6 area (

Understanding Starbursting Protoclusters: Follow-up of Herschel-Planck Selected Sources [PDF]
, 2017 Crossmatching between Planck and Herschel data has uncovered a total of 30 high-z candidate starbursting protoclusters in HerMES & H-ATLAS. These protoclusters might be in their formation period so their study is important in characterising cluster ...

Protoclusters in the ΛCDM Universe
The Astrophysical Journal, 2006 We compare the highly clustered populations of very high redshift galaxies with protoclusters identified numerically in a standard ΛCDM universe (Ω0 = 0.3, λ0 = 0.7) simulation. We evolve 2563 dark matter particles in a comoving box of side 150 h-1 Mpc.

FRAGMENTATION OF MOLECULAR CLUMPS AND FORMATION OF A PROTOCLUSTER [PDF]
The Astrophysical Journal, 2015 Sufficiently massive clumps of molecular gas collapse under self-gravity and fragment to spawn a cluster of stars that have a range of masses. We investigate observationally the early stages of formation of a stellar cluster in a massive filamentary infrared dark cloud, G28.34+0.06 P1, in the 1.3mm continuum and spectral line emission using the ALMA ...

A giant protocluster of galaxies at redshift 5.7 [PDF]
Nature Astronomy, 2018 Galaxy clusters trace the largest structures of the Universe and provide ideal laboratories for studying galaxy evolution and cosmology. Clusters with extended X-ray emission have been discovered at redshifts up to z ~ 2.5. Meanwhile, there has been growing interest in hunting for protoclusters, the progenitors of clusters, at higher redshifts.
