The host galaxies of high-redshift quasars [PDF]

open access: yes, 2020
© 2020 Madeline Anne MarshallIn the early Universe, we observe supermassive black holes with masses of up to a billion times the mass of the Sun, accreting at or even above the Eddington limit.

Simulating high-redshift galaxies [PDF]

open access: yes, 2011
Recent observations have gathered a considerable sample of high-redshift galaxy candidates and determined the evolution of their luminosity function (LF). To interpret these findings, we use cosmological SPH simulations including, in addition to standard

Constraining dark energy using real and mock galaxy surveys [PDF]

open access: yes, 2009
In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Cosmological constraints from the clustering of the Sloan Digital Sky Survey DR7 luminous red galaxies [PDF]

open access: yes, 2009
We present the power spectrum of the reconstructed halo density field derived from a sample of luminous red galaxies (LRGs) from the Sloan Digital Sky Survey (SDSS) Seventh Data Release (DR7).

The AZTEC/SMA interferometric imaging survey of submillimeter-selected high-redshift galaxies [PDF]

open access: yes, 2009
We present results from a continuing interferometric survey of high-redshift submillimeter galaxies with the Submillimeter Array, including high-resolution (beam size ∼ 2 arcsec) imaging of eight additional AzTEC 1.1mm selected sources in the COSMOS ...

MAMMOTH-Subaru. IV. Large Scale Structure and Clustering Analysis of Lyα Emitters and Lyα Blobs at z = 2.2–2.3

open access: yesThe Astrophysical Journal
We report the large scale structure and clustering analysis of Ly α emitters (LAEs) and Ly α blobs (LABs) at z  = 2.2–2.3. Using 3341 LAEs, 117 LABs, and 58 bright (Ly α luminosity L _Ly _α  > 10 ^43.4 erg s ^−1 ) LABs at z  = 2.2–2.3 selected with ...

Surveys of High-Redshift Galaxies

open access: yes, 2013
This chapter details the study of high-redshift galaxies. It first outlines the telescopes used for observing these galaxies: the Hubble Space Telescope (HST) and its follow ups, as well as the next-generation telescopes such as the James Webb Space ...
