Faint galaxy photometry and cosmology [PDF]
, 1985 Deep galaxy catalogues have been constructed from automatic measurements of photographic plates by the COSMOS machine at the Royal Observatory Edinburgh. The plates were taken by the 1.2m UK Schmidt telescope (UKST) and 4m Anglo-Australian telescope (AAT)

The Astrophysical JournalWe measure the evolution of the rest-frame near-ultraviolet (NUV)− V colors for early-type galaxies in clusters at 0 < z < 1.1 using data from the Hyper Suprime-Cam Subaru Strategic Program, CFHT Large Area U -band Deep Survey, and local Sloan Digital ...

Objective-prism and slit-spectra redshifts in a study of the distribution of galaxies
, 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.

Probing the star formation history of early-type galaxies in clusters [PDF]
, 1998 In this thesis, we present a new photometric catalogue of the local Coma galaxy cluster in the Johnson U- and V- bands. We cover an area of 3360arcmin(^2) of sky, to a depth of V = 20mag in a 13 arcsec diameter aperture, and produce magnitudes for ~ 1400

UV Spectral Slope and Nebular Dust Attenuation in Dwarf Galaxies at 1.4 < z < 2.6
The Astrophysical JournalWe analyze nebular dust attenuation and its correlation with stellar mass ( M _* ) and ultraviolet (UV) spectral slope ( β ) in 33 lensed, low-mass star-forming galaxies at 1.4 ≤ z ≤ 2.6, using Keck/Multi-Object Spectrometer For IR Exploration (MOSFIRE ...

, 2010 We measure the half-light radii of globular clusters (GCs) in 43 galaxies from the Advanced Camera for Surveys (ACS) Fornax Cluster Survey. We use these data to extend previous work in which the environmental dependencies of the half-light radii of GCs ...

Structure and Kinematics of Star-forming Elliptical Galaxies in SDSS-MaNGA
The Astrophysical JournalUsing “spatially” resolved spectroscopy, we investigated the characteristics and different modes of formation of stars in elliptical galaxies. We identified an unusual population of 59 star-forming elliptical (SF-E) galaxies in SDSS-MaNGA, our primary ...

The nature of early-type galaxies in hierarchical models [PDF]
, 2008 In this Thesis we describe the properties of early-type galaxies in the context of hierarchical galaxy formation. We use two variants of the GALFORM model originally introduced by Cole et al.: the Baugh et al. and the Bower et al. models.

Elliptical galaxies: fundamental relations, environmental effects and peculiar motions [PDF]
, 1993 This thesis investigates the reliability of the D - σ and D - Mg(_2) distance indicators for elliptical galaxies. In particular, we test whether these empirical correlations are affected by differences in the stellar populations of elliptical galaxies ...

The Astrophysical JournalWe present a new constraint on the primordial helium abundance, Y _P , based on Subaru observations. A major source of uncertainty in previous Y _P determinations is the lack of extremely metal-poor galaxies (EMPGs; 0.01–0.1 Z _⊙ ), which have ...
