Characterising and identifying galaxy protoclusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
We study the characteristics of galaxy protoclusters using the latest L-GALAXIES semi-analytic model. Searching for protoclusters on a scale of ~10 cMpc gives an excellent compromise between the completeness and purity of their galaxy populations, leads ...

Galaxy evolution in protoclusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
We investigate galaxy evolution in protoclusters using a semi-analytic model applied to the Millennium Simulation, scaled to a Planck cosmology. We show that the model reproduces the observed behaviour of the star formation history (SFH) both in ...

Are Ly α emitters segregated in protoclusters regions? [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
The presence of neutral hydrogen in the inter-stellar medium (ISM) and inter-galactic medium (IGM) induces radiative transfer (RT) effects on Ly α photons which affect the observability of Lyman alpha emitters (LAEs).

Dusty Galaxies in Protoclusters

, 2017
Comparison of Herschel and Planck sources in large area surveys has revealed a pop- ulation of objects that appear to be galaxy clusters or protoclusters, many of whose members are undergoing massive starbursts.

How galaxies form in protoclusters [PDF]

, 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

MAGAZ3NE: Evidence for Galactic Conformity in z ≳ 3 Protoclusters

The Astrophysical Journal
We examine the quiescent fractions of massive galaxies in six z ≳ 3 spectroscopically confirmed protoclusters in the COSMOS field, one of which is newly confirmed and presented here. We report the spectroscopic confirmation of MAGAZ3NE J100143+023021 at $

Protoclusters associated with [PDF]

Astronomy & Astrophysics, 2006
We present the results of a large program conducted with the Very Large Telescope and augmented by observations with the Keck telescope to search for forming clusters of galaxies near powerful radio galaxies at $2.0 < z < 5.2$.

Herschel protocluster survey: a search for dusty star-forming galaxies in protoclusters at z = 2–3 [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We present a Herschel/SPIRE survey of three protoclusters at z = 2 − 3 (2QZCluster, HS1700, SSA22). Based on the SPIRE colours (S350/S250 and S500/S350) of 250 μm sources, we selected high redshift dusty star-forming galaxies potentially associated with ...

ODIN: High Clustering Strength of Protoclusters at Cosmic Noon

The Astrophysical Journal
The One-hundred-deg ^2 DECam Imaging in Narrowbands (ODIN) survey is carrying out a systematic search for protoclusters during Cosmic Noon, using Ly α -emitting galaxies (LAEs) as tracers.

Subclustering and Star Formation Efficiency in Three Protoclusters in the Central Molecular Zone

The Astrophysical Journal Letters
We present the highest-resolution (∼0 $\mathop{.}\limits^{^{\prime\prime} }$ 04) Atacama Large Millimeter/submillimeter Array 1.3 mm continuum observations so far of three massive star-forming clumps in the Central Molecular Zone (CMZ), namely 20 km s ...
