Modeling the Multiwavelength Detection of Protoclusters. I. An Excess of Submillimeter Galaxies in Protocluster Cores

Astrophysical Journal
Studies of galaxy protoclusters yield insights into galaxy cluster formation complementary to those obtained via “archaeological” studies of present-day galaxy clusters.

The Young and the Wild: What Happens to Protoclusters Forming at Redshift z ≈ 4?

Astrophysical Journal, 2023
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 the well-observed protocluster SPT2349-56.

Tracing the Total Stellar Mass and Star Formation of High-redshift Protoclusters

The Astrophysical Journal, 2023
As the progenitors of present-day galaxy clusters, protoclusters are excellent laboratories to study galaxy evolution. Since existing observations of protoclusters are limited to the detected constituent galaxies at UV and/or infrared wavelengths, the ...

The ALMA Survey of Star Formation and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE): Core Growth, Cluster Contraction, and Primordial Mass Segregation

The Astrophysical Journal Supplement Series, 2023
The Atacama Large Millimeter/submillimeter Array (ALMA) Survey of Star Formation and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE) aims to investigate the process of mass assembly and its connection to high-mass star formation theories

ODIN: Where Do Lyα Blobs Live? Contextualizing Blob Environments within Large-scale Structure

The Astrophysical Journal, 2023
While many Ly α blobs (LABs) are found in and around several well-known protoclusters at high redshift, how they trace the underlying large-scale structure is still poorly understood. In this work, we utilize 5352 Ly α emitters (LAEs) and 129 LABs at z =

Stellar Feedback in Molecular Clouds and its Influence on the Mass Function of Young Star Clusters [PDF]

, 2010
We investigate how the removal of interstellar material by stellar feedback limits the efficiency of star formation in molecular clouds and how this determines the shape of the mass function of young star clusters.

Disk Dissipation, Giant Planet Formation, and Star Formation Rate Fluctuations in the 3 Myr History of Gould’s Belt

The Astrophysical Journal, 2023
Although episodic star formation (SF) has been suggested for nearby SF regions, a panoramic view of the recent episodic SF history in the solar neighborhood is still missing. By uniformly constraining the slope α of infrared spectral energy distributions

COSMOS2020: Discovery of a Protocluster of Massive Quiescent Galaxies at z = 2.77

The Astrophysical Journal Letters, 2023
Protoclusters of galaxies have been found in the last quarter-century. However, most of them have been found through the overdensity of star-forming galaxies, and there have been no known structures identified by more than two spectroscopically confirmed

Exploring Project Complexity through Project Failure Factors: Analysis of Cluster Patterns Using Self‐Organizing Maps

Complexity, Volume 2018, Issue 1, 2018., 2018
In the field of project management, complexity is closely related to project outcomes and hence project success and failure factors. Subjectivity is inherent to these concepts, which are also influenced by sectorial, cultural, and geographical differences.
