ALMA-IMF. XIV. Free–Free Templates Derived from H41α and Ionized Gas Content in 15 Massive Protoclusters

The Astrophysical Journal Supplement Series
We use the H41 α recombination line to create templates of the millimeter free–free emission in the ALMA-IMF continuum maps, which allows us to separate it from dust emission.

Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at z ≥ 10?

The Astrophysical Journal Letters, 2023
Recent photometric detections of extreme ( z > 10) redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation and in the most acute case, in tension with ΛCDM itself.

MeerKAT observations of Herschel protocluster candidates

Monthly Notices of the Royal Astronomical Society
ABSTRACT High-redshift protoclusters consisting of dusty starbursts are thought to play an important role in galaxy evolution. Their dusty nature makes them bright in the far-infrared (FIR)/submm but difficult to find in optical/near-infrared (NIR) surveys.

The Young and the Wild: What happens to Protoclusters forming at z = 4? [PDF]

, 2022
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 SPT2349-56.

LATIS: A Sample of IGM-selected Protoclusters and Protogroups at z ∼ 2.5

The Astrophysical Journal
The Ly α Tomography IMACS Survey (LATIS) has produced large 3D maps of the intergalactic medium (IGM), providing a new window on the cosmic web at z ∼ 2.5.

A Massive Protocluster Anchored by a Luminous Quasar at z = 6.63

The Astrophysical Journal Letters
Protoclusters, the progenitors of galaxy clusters, trace large scale structures in the early Universe and are important to our understanding of structure formation and galaxy evolution. To date, only a handful of protoclusters have been identified in the

ODIN: Confirmation and 3D Reconstruction of Six Massive Protoclusters at Cosmic Noon

The Astrophysical Journal
Protoclusters represent sites of accelerated galaxy formation and extreme astrophysical activity characteristic of dense environments. Identifying massive protoclusters and mapping their spatial structures are therefore crucial for understanding how ...
