Before its time: A remarkably evolved protocluster core at z = 7.88

Astronomy & Astrophysics
Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed by large gas reservoirs.

Matched filtering with interferometric 21cm experiments

, 2017
A new generation of interferometric instruments is emerging which aim to use intensity mapping of redshifted $21\,$cm radiation to measure the large-scale structure of the Universe at $z\simeq 1-2$ over wide areas of sky.

The Manhattan Suite: Accelerated Galaxy Evolution in the Early Universe

The Astrophysical Journal
Observational advances have allowed the detection of galaxies, protoclusters, and galaxy clusters at higher and higher redshifts, opening a new view into extreme galaxy evolution.

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 ...

The ALMA-QUARKS Survey: Hot Molecular Cores Are a Long-standing Phenomenon in the Evolution of Massive Protostars

The Astrophysical Journal
We present an analysis of the QUARKS survey sample, focusing on protoclusters where hot molecular cores (HMCs; traced by CH _3 CN (12–11)) and HC/UC H ii regions (traced by H30 α /H40 α ) coexist.

The Bigfoot: A Footprint of a Coma Cluster Progenitor at z = 3.98

The Astrophysical Journal Letters
Protoclusters, galaxy clusters’ high-redshift progenitors, hold the key to understanding the formation and evolution of clusters and their member galaxies. However, their cosmological distances and spatial extensions (tens of Mpc) have inhibited complete

Temperature and kinematics of protoclusters with intermediate and high-mass stars: the case of IRAS 05345+3157

, 2012
We have mapped at small spatial scales the temperature and the velocity field in the protocluster associated with IRAS 05345+3157, which contains both intermediate-/high-mass protostellar candidates and starless condensations, and is thus an excellent ...

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.
