Is there enough star formation in simulated protoclusters? [PDF]

, 2021
As progenitors of the most massive objects, protoclusters are key to tracing the evolution and star formation history of the Universe, and are responsible for ≳ 20 per cent of the cosmic star formation at z, > 2.

Building blocks of the universe:The search for galaxy protoclusters

, 2023
Galaxy clusters are the most massive virialized structures in the presentday Universe, containing thousands of galaxies. Since the dawn of the concept of galaxies, astronomers have been studying the distribution of galaxies across the sky and found them ...

Protocluster survey/characterization with NGRST

, 2021
Protoclusters are interesting laboratories of galaxy evolution. To study their typical properties, first of all, deep and wide surveys are required since their surface density is quite small (a few in deg^2). Based on the deep and wide survey in optical by Hyper Suprime-Cam Subaru Strategic Program, the largest (N=179 in 121 deg^2) and uniform catalog ...

Not all protoclusters host evolved galaxies: Evidence for reduced environmental effects in a lower halo mass protocluster at z = 7.66

Astronomy & Astrophysics
The progenitors of present-day galaxy clusters offer crucial insight into how galaxies and large-scale structure co-evolve in the early Universe. We present JWST/NIRCam grism spectroscopy of the photometrically identified z = 7.66 protocluster core in ...

Tracking Protostellar Variability in Massive Protoclusters with ALMA. I. Insights from QUARKS and MaMMOtH

The Astrophysical Journal
Millimeter/submillimeter variability is often attributed to dynamical disk-mediated accretion, yet detection is limited to low-mass protostars in nearby clouds.

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

ALMA-IMF

Astronomy & Astrophysics
Aims. The gravoturbulent fragmentation of the interstellar medium is expected to create a hierarchical cascade of cloud structures, crossing the scales from core to disk.
