ODIN: Identifying Protoclusters and Cosmic Filaments Traced by Lyα-emitting Galaxies

The Astrophysical Journal
To understand the formation and evolution of massive cosmic structures, studying them at high redshift, in the epoch when they formed the majority of their mass, is essential.

Discovery of a high-z protocluster with tunable filters: the case of 6C0140+326 at z=4.4

, 2011
We present the first results obtained using a tunable narrowband filter in the search for high-z protoclusters. Using the recently commissioned red tunable filter on the Gran Telescopio Canarias we have searched for Lya emitters in a 75 arcmin^2 field ...

DEIMOS spectroscopy of z = 6 protocluster candidate in COSMOS – a massive protocluster embedded in a large-scale structure?

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT We present the results of our Keck/DEep Imaging Multi-Object Spectrograph spectroscopic follow-up of candidate galaxies of i-band-dropout protocluster candidate galaxies at z ∼ 6 in the COSMOS field. We securely detect Lyman α emission lines in 14 of the 30 objects targeted, 10 of them being at z = 6 with a signal-to-noise ratio

ALMA Fragmented Source Catalog in Orion (FraSCO). I. Outflow Interaction within an Embedded Cluster in OMC-2/FIR 3, FIR 4, and FIR 5

The Astrophysical Journal, 2023
We present a high-angular resolution (∼1″) and wide-field ( $2\buildrel{\,\prime}\over{.} 9\times 1\buildrel{\,\prime}\over{.} 9$ ) image of the 1.3 mm continuum, CO( J = 2–1) and SiO( J = 5–4) line emissions toward an embedded protocluster, FIR 3, FIR 4,

A High-Resolution Hubble Space Telescope Study of Apparent Lyman Continuum Leakers at $z\sim3$ [PDF]

, 2015
We present $U_{336}V_{606}J_{125}H_{160}$ follow-up $HST$ observations of 16 $z\sim3$ candidate LyC emitters in the HS1549+1919 field. With these data, we obtain high spatial-resolution photometric redshifts of all sub-arcsecond components of the LyC ...

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. Followup studies confirm the likely clus- ter/protocluster nature of these sources.

THECHANDRADEEP PROTOCLUSTER SURVEY: EVIDENCE FOR AN ENHANCEMENT OF AGN ACTIVITY IN THE SSA22 PROTOCLUSTER ATz= 3.09 [PDF]

The Astrophysical Journal, 2009
We present results from a new ultra-deep 400 ks Chandra observation of the SSA22 protocluster at z = 3.09. We have studied the X-ray properties of 234 z ~ 3 Lyman break galaxies (LBGs; protocluster and field) and 158 z = 3.09 Ly-alpha emitters (LAEs) in SSA22 to measure the influence of the high-density protocluster environment on the accretion ...

LATIS: Comparing Galaxy and IGM Tomography Maps as Tracers of Large-scale Structure and Protoclusters at z ∼ 2.5

The Astrophysical Journal
We investigate the consistency of intergalactic medium (IGM) tomography and galaxy surveys as tracers of the cosmic web and protoclusters at z  ∼ 2.5. We use maps from the Ly α Tomography IMACS Survey (LATIS), which trace the distributions of Lyman-break

A SINFONI view of flies in the Spiderweb: a galaxy cluster in the making

, 2011
The environment of the high-z radio galaxy PKS 1138-262 at z~2.2 is a prime example of a forming galaxy cluster. We use deep SINFONI data to perform a detailed study of the kinematics of the galaxies within 60 kpc of the radio core and we link this to ...
