Highlights of Astronomy, 1977 I would like to report on some work that Ed Turner and I have done on groups of galaxies and how groups may be used to obtain useful cosmological information. Of course the classic study of groups of galaxies was done by de Vaucouleurs (1975) who made a catalogue of groups and loose associations of galaxies in the local supercluster. Partly to obtain a

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

Detection of a Spatially Extended Stellar Population in M33: A Shallow Stellar Halo?
The Astrophysical JournalWe analyze the outer regions of M33, beyond 15 kpc in projected distance from its center, using Subaru/Hyper Suprime-Cam multicolor imaging. We identify red giant branch (RGB) stars and red clump (RC) stars using the surface-gravity-sensitive NB515 ...

Galaxy Groups at Intermediate Redshift [PDF]
The Astrophysical Journal, 2001 Galaxy groups likely to be virialized are identified within the CNOC2 intermediate redshift galaxy survey using an iterative method. The number-velocity dispersion relation is in agreement with the low-mass extrapolation of the cluster normalized Press-Schechter function.

The effect of the environment on the evolution of galaxy colours [PDF]
, 2006 In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...

A group of merging galaxies falling into Abell 2142
Astronomy & AstrophysicsGalaxy clusters produce a very hostile environment for galaxies: their gas gets stripped by ram pressure, they undergo galaxy interactions, and their star formation is quenched.

Optical observations of M81 galaxy group in narrow band [SII] and Hα filters: Holmberg IX [PDF]
Serbian Astronomical Journal, 2009 We present observations of the nearby tidal dwarf galaxy Holmberg IX in M81 galaxy group in narrow band [SII] and Hα filters, carried out in March and November 2008 with the 2m RCC telescope at NAO Rozhen, Bulgaria.
