Protocluster Assembly: Observations And Theory

open access: yes, 2017
In this review talk I give an overview of the theory of protocluster formation and assembly in terms of Lambda-CDM cosmology. I describe the implications of hierarchical and stochastic cluster assembly. I report on recent observations that illuminate the assembly of clusters, focussing on the distribution and velocity structure of protocluster galaxies,

Kinematic Analysis of z = 4.3 Galaxies in the SPT2349–56 Protocluster Core

open access: yesThe Astrophysical Journal
SPT2349−56 is a protocluster discovered in the 2500 deg ^2 South Pole Telescope (SPT) survey. In this paper, we study the kinematics of the galaxies found in the core of SPT2349−56 using high-resolution (1.55 kpc spatial resolution at z = 4.303 ...

The Timescales of Embedded Star Formation as Observed in STARFORGE

open access: yesThe Astrophysical Journal
Star formation occurs within dusty molecular clouds that are then disrupted by stellar feedback. However, the timing and physical mechanisms that govern the transition from deeply embedded to exposed stars remain uncertain.

Galaxy populations of protoclusters in cosmological hydrodynamical simulations

open access: yesAstronomy & Astrophysics
Context. The study of protoclusters at cosmic noon is essential for understanding the impact of the environment and of the transformational processes occurring during this epoch on galaxy properties. Aims. This work tests the predictions regarding galaxy evolution of the DIANOGA cosmological hydrodynamical simulations of cluster progenitors at z = 2.2 ...

Selecting Clusters and Protoclusters via Stellar Mass Density. II. Application to HSC-SSP Observations

open access: yesThe Astrophysical Journal
We present a selection of candidates of clusters and protoclusters of galaxies identified in the photometric data of the HSC-SSP Wide Public Data Release 3 (PDR3), spanning the redshift range 0.1 ≤ z ≤ 2. The selection method, detailed in Vicentin et al.,

MAMMOTH-MOSFIRE: Environmental Effects on Galaxy Interstellar Medium at z ∼ 2

open access: yesThe Astrophysical Journal
The MAMMOTH-MOSFIRE program is a deep Keck/MOSFIRE K -band spectroscopic follow-up of emission-line galaxies identified in the MAMMOTH-Grism Hubble Space Telescope/wide-field camera 3 G141 slitless spectroscopic survey, targeting the core regions of the ...
