Results 131 to 140 of about 15,250,094 (223)
We present the results of near-infrared spectroscopy using Keck/MOSFIRE for 23 member galaxies in the X-ray cluster XCS 2215 ( z = 1.46) to investigate the environmental dependence of gaseous flows and metallicities.

A faint galaxy redshift survey behind massive clusters [PDF]
This thesis is concerned with the gravitational lensing effect by massive galaxy clusters. We have explored a new technique for measuring galaxy masses and for detecting high-z galaxies by their optical colors.

Self-consistent Combined HST, K-band, and Spitzer Photometric Catalogs of the BUFFALO Survey Fields
This article presents new astronomical source catalogs using data from the BUFFALO Survey. These catalogs contain detailed information for over 100,000 astronomical sources in the six BUFFALO clusters: A370, A2744, AS1063, MACS 0416, MACS 0717, and MACS ...

The evolution of radio galaxies - A VLA survey of high-redshift clusters of galaxies
We present data from a VLA 1465 MHz survey of high-redshift galaxy clusters with redshifts of 0.25 to 0.9. We detect sources in 13 of 55 clusters. The sample shows strong evolution of the radio luminosity function (RLF) during this period even for weak cluster radio galaxies, i.e., those with 24 ...

Extreme emission line galaxies (EELGs) at high redshifts are considered key contributors to cosmic reionization at z > 6 due to their higher ionization efficiencies.

Simulating supernova feedback in galaxy disks [PDF]
In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

We present new Hubble Space Telescope/Wide Field Camera 3 G141 grism observations for COBRA 1411+3415, originally identified as a high-redshift cluster candidate in the Clusters Occupied by Bent Radio AGN (COBRA) survey using radio, infrared, and optical

Galaxy clustering and galaxy clusters from the UKIDSS DXS [PDF]
Recent wide and deep surveys allow us to investigate the large scale structure of the Universe at high redshift. We present studies of the clustering of high redshift galaxies and galaxy clusters, using reprocessed UKIDSS DXS catalogues.

ODIN: Characterizing the Three-dimensional Structure of Two Protocluster Complexes at z = 3.1
We present a detailed study of the 3D morphology of two extended associations of multiple protoclusters at z = 3.1. These protocluster “complexes,” designated COSMOS-z3.1-A and COSMOS-z3.1-C, are the most prominent overdensities of z = 3.1 Ly α emitters (

Probing the large-scale structure of the universe with future galaxy redshift surveys [PDF]
Several projects are currently underway to obtain large galaxy redshift surveys over the course of the next decade. The aim of this thesis is to study how well the resultant three-dimensional maps of the galaxy distribution will be able to constrain the ...
