First results from high redshift quasar searches in VIKING [PDF]
, 2012 This thesis presents the discovery of the first luminous z & 6.5 quasars in the VISTA kilo-degree Infrared Galaxy Survey (VIKING). After some basic quality control, quasar selection is investigated via use of initial data supplementedwith ...

Is There a Missing Galaxy Problem at High Redshift? [PDF]
The Astrophysical Journal, 2004 We study the evolution of the global stellar mass density in a Lambda cold dark matter universe using two different types of hydrodynamical simulations (Eulerian TVD and SPH) and the analytical model of Hernquist & Springel (2003). We find that the theoretical calculations all predict both a higher stellar mass density at z~3 than indicated by ...

Objective-prism and slit-spectra redshifts in a study of the distribution of galaxies [PDF]
, 2014 A thorough and detailed investigation into the accuracy, reliability and consistency of the objective-prism redshift technique with changes in plate material, measuring machine and reduction techniques has been undertaken.

High-Redshift Radio Galaxies [PDF]
Highlights of Astronomy, 1995 Radio galaxies are unique cosmological probes. As with radio-loud quasars, the presence of luminous radio continuum and optical line emission enable radio galaxies to be observed and recognized at large distances, up to z = 4.2. However, unlike the situation for most quasars, their optical emission can be spatially resolved from the ground and studied ...

On the Number of Galaxies at High Redshift [PDF]
Galaxies, 2015 The number of galaxies at a given flux as a function of the redshift, z, is derived when the z-distance relation is non-standard. In order to compare different models, the same formalism is also applied to the standard cosmology. The observed luminosity function for galaxies of the zCOSMOS catalog at different redshifts is modeled by a new luminosity ...

The circumgalactic medium of high-redshift galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract We study the properties of the circumgalactic medium (CGM) of high-z galaxies in the metal enrichment simulations presented in Pallottini et al. At z = 4, we find that the simulated CGM gas density profiles are self-similar, once scaled with the virial radius of the parent dark matter halo.
