Dust-Obscured Galaxy Protocluster and Cluster Survey (DOGPACS): Identifying Large-Scale Structures 9−10 Billion Light-Years Away
… studies have identified distant clusters and protoclusters due to advanced observational strategies. However, the protocluster-to-cluster transformation is still unclear, mainly due to the lack of large samples of early-stage clusters and late-stage protoclusters. Our research has identified a …

No evidence for millimeter continuum source overdensities in the environments of z [greater than approximately] 6 quasars
… excess continuum emission as evidence for early protoclusters. We compare the detection rates of continuum sources at [greater than or equal to] 5σ significance in the fields surrounding the quasars (A [subscript eff] = 4.3 arcmin²) with millimeter number counts in blank field surveys. We …

Large-scale molecular dynamics investigations of ion-induced compositional dynamics leading to nanopattern formation at semiconductor surfaces
… a compositional depth profile. However, smaller “protoclusters” of Sb were formed in the subsurface, even in the absence of the compositional change necessary to drive thermodynamic phase separation. These protoclusters are conjectured to be formed from Sb precipitation out of the GaSb melt volume …
