We have analysed deep R-band images, down to a limiting surface brightness of 26.5 R-mag arcsec$^{-2}$ (equivalent to ~28 B-mag arcsec$^{-2}$), of 5 cD galaxies to determine the shape of the surface...
The Millennium Galaxy Catalogue: Galaxy Bimodality (2006)
Driver, Simon P., Liske, Jochen, Graham, Alister W.
Galaxy bimodality is caused by the bulge-disc nature of galaxies as opposed to two distinct galaxy classes. This is evident in the colour-structure plane which clearly shows that elliptical galaxies...
Graham, Alister W., Merritt, David, Moore, Ben, Diemand, Juerg, Terzic, Balsa
We have recently shown that both the Prugniel-Simien model and Sersic's function (hereafter referred to as the Einasto model when applied to internal density profiles) describe simulated dark matter...
Graham, Alister W., Merritt, David, Moore, Ben, Diemand, Juerg, Terzic, Balsa

Busarello, G., Lanzoni, B., Capaccioli, M., Longo, G., Colless, Matthew, Graham, Alister W.
By making use of extended kinematical data for a sample of ellipticals, we address the problem of the claimed existence of a relation between mass and mass-to-light ratio. We show that dynamical...
The M/L ratio along the major-axis of NGC 1399 (1998)
Graham, Alister W., Colless, Matthew, Busarello, G.
In this paper, we derive the mass-to-light ratio profile for the Fornax elliptical galaxy NGC 1399 from the observed intensity and velocity dispersion measurements along its major-axis.
This paper presents an extension to the work of D'Onofrio et al. (1997) on the Fundamental Plane (FP), in which a distance modulus between the Virgo and Fornax clusters was derived. In addressing the...
Merluzzi, P., Busarello, G., Terranegra, L., Colless, Matthew, Graham, Alister W.
We summarise the main results of our study of NGC 1428, an early-type galaxy belonging to the Fornax cluster. By means of long-slit spectroscopic data we study it's kinematics and also solve the...

Extended stellar kinematics of elliptical galaxies in the Fornax cluster (1998)
Graham, Alister W., Colless, Matthew, Busarello, G., Zaggia, S., Longo, G.
We present extended stellar kinematics for a sample of elliptical galaxies in the Fornax cluster. Out of the 13 galaxies presented here, five (FCC 119, FCC 136, NGC 1373, NGC 1428, FCC 335) have no...
The M/L versus M relation and the tilt of the Fundamental Plane (1998)

Some effects of galaxy structure and dynamics on the Fundamental Plane (1997)
Graham, Alister W., Colless, Matthew
We examine the effects on the Fundamental Plane (FP) of structural departures from an R1/4 galaxy light profile. We also explore the use of spatial (i.e., volumetric) as well as projected galaxy...

Variable mass structure and the Fundamental Plane (1997)
Graham, Alister W., Colless, Matthew
We examine the influence of broken structural homology upon the Fundamental Plane (FP). We fit the Sersic R1/n law, being the generalized R1/4 law, where 'n' is a free parameter that accommodates...

Brightest cluster galaxy profile shapes (1996)
Graham, Alister W., Lauer, T. R., Colless, Matthew, Postman, M.
We model the surface brightness profiles of an observed sample of 119 Abell Brightest Cluster Galaxies (BCG), finding a generalised deVaucouleurs r^1/n law, where n is a free parameter, to be...
