Spectral Energy Distributions of Galaxies in Moderate Redshift Clusters
We have observed 3 moderate redshift clusters using a combination of 7 intermediate band filters and 2 CCDs in order to derive photometric information for cluster galaxies from 400 nm to 900 nm. Preliminary re...

Fibre Optic Spectra and the Dynamics of Sersic 40/6
For the study of the dynamics of rich clusters of galaxies it is important to know rather precise radial velocities of fairly large numbers of cluster galaxies. Kent and Gunn (1982) have analysed the surface d...

Elliptical Galaxies with Shells
A considerable number of otherwise normal elliptical galaxies show sharp edged, low surface brightness concentric features, often at very large radii from the parent galaxy. Features like this are visible in s...

Two Colour CCD Photometry of Malin-Carter Shell Galaxies
Shells may be the result of the disruption of a small companion in the potential of a much larger galaxy (e.g., Hernquist & Quinn, 1986; Dupraz & Combes, 1985), the disturbance of a disk system in a tidal enco...

An optical and radio survey of southern radio galaxies
We present results from a subset of our survey of southern elliptical radio galaxies. Using VLA snapshot data and high sensitivity spectra from tile AAT Faint Object Red Spectrograph we find a strong correlati...

0422-476: A Shell Galaxy with Non-Aligned Shells
0422-476, a nearly face-on S0-a galaxy, is the best example in the Malin/Carter (1983) catalogue of a shell system with shells distributed randomly “all-round” the galaxy. The shells are so bright ...

Fibre optics at the 4.2 m telescope (WHT)
We summarize some of the work on optical fibres carried out at the 4.2 m (WHT) telescope. We will briefly describe the Fibre Linked Experimental spectrograph.

New D — σ Results for Coma Ellipticals
We discuss D — σ results for a new sample of ellipticals in the Coma cluster. Unlike previous studies, our sample includes many ellipticals that lie well outside the cluster core. These data have been used to est...

Peculiar Kinematics in the Core of NGC 474
We present absorption line profile analysis of NGC 474, an elliptical with prominent, irregular shells. Profiles are parameterized with Gauss-Hermite polynomials (van der Marel & Franx ApJ 407 1993; Rix & Whit...

Scheduled Discoveries of 7+ High-Redshift Supernovae:First Cosmology Results and Bounds on q 0
Our search for high-redshift Type Ia supernovae discovered, in its first years, a sample of seven supernovae. Using a “batch” search strategy, almost all were discovered before maximum light and were observed ...

Observation of Cosmological Time Dilation Using Type Ia Supernovae as Clocks
This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0.3 — 0.5, before or at maximum l...

The Type Ia Supernova Rate at z ~ 0.4
We present the first measurement of the rate of Type Ia supernovae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as described in more detail at this ...

Shells, Ripples and Tails
It has been known since the early simulations of Wright (1972), and Toomre & Toomre (1972), that interactions between galaxies can give rise to quite spectacular morphological features, including spiral struct...

Shell Formation in Ngc 474
We present broad band photometry (B and R) of the classic shell galaxy NGC 474. Preliminary results indicate that the shells have a similar colour to and follow the same trend of colour with radius as the unde...

Map** the Stellar Dynamics of M31
Using the Planetary Nebula Spectrograph, we have observed and measured the velocities for 2764 PNe in the disk and halo of the Andromeda galaxy. Preliminary analysis using a basic ring model shows a rotation c...

Liverpool telescope 2: a new robotic facility for rapid transient follow-up
The Liverpool Telescope is one of the world’s premier facilities for time domain astronomy. The time domain landscape is set to radically change in the coming decade, with synoptic all-sky surveys such as LSST...
