Digging into the Interior of Hot Cores with ALMA (DIHCA). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions

The Astrophysical Journal
Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process of how multiple stellar systems form is incomplete and biased toward nearby ...

Identification of Galaxy Protoclusters Based on the Spherical Top-hat Collapse Theory

The Astrophysical Journal
We propose a new method for finding galaxy protoclusters that is motivated by structure formation theory and also directly applicable to observations. We adopt the conventional definition that a protocluster is a galaxy group whose virial mass M _vir < M

A Survey of Sulfur-bearing Molecular Lines toward the Dense Cores in 11 Massive Protoclusters

The Astrophysical Journal Supplement Series
Sulfur-bearing molecules are commonly detected in dense cores within star-forming regions, but the total sulfur budget is significantly lower when compared to the interstellar medium value.

High Redshift Clusters and Protoclusters

, 1999
Our understanding of the cosmic history of galaxy clusters has recently been enhanced due to an extensive series of observations including faint spectroscopic data (especially those obtained at the Keck Observatory), deep optical and NIR imaging from the ground and in space, morphological data from HST, and new constraints on the evolution of the ...

The One-hundred-deg2 DECam Imaging in Narrowbands (ODIN): Survey Design and Science Goals

The Astrophysical Journal
We describe the survey design and science goals for One-hundred-deg ^2 DECam Imaging in Narrowbands (ODIN), a NOIRLab survey using the Dark Energy Camera (DECam) to obtain deep (AB ∼ 25.7) narrowband images over an unprecedented area of sky.

How Galaxies Form In Protoclusters

, 2017
I will describe the cosmic star formation history of cluster galaxies using observations of clusters and protoclusters from z = 0 to 4. I will show that the star formation history of clusters differs from the global cosmic star formation history: cluster galaxies typically form their stars earlier and over a shorter period of time.

Evidence for Environmental Effects in the z = 4.3 Protocluster Core SPT2349–56

The Astrophysical Journal Letters
We present Atacama Large Millimeter/submillimeter Array observations of the [C I ] 492 and 806 GHz fine-structure lines in 25 dusty star-forming galaxies (DSFGs) at z = 4.3 in the core of the SPT2349–56 protocluster.

JWST’s First Glimpse of a z > 2 Forming Cluster Reveals a Top-heavy Stellar Mass Function

The Astrophysical Journal Letters
Clusters and their progenitors (protoclusters) at z ∼ 2 − 4, the peak epoch of star formation, are ideal laboratories to study the formation process of both the clusters themselves and their member galaxies.
