A class of compact dwarf galaxies from disruptive processes in galaxy clusters
Dwarf galaxies have attracted increased attention in recent years, because of their susceptibility to galaxy transformation processes within rich galaxy clusters1,2,3. Direct evidence for these processes, however...

A Complete 2dF Survey of Fornax
We are using the 2dF spectrograph on the Anglo-Australian Telescope to obtain spectra for a complete sample of all 14000 objects with 16.5 < B < 19.7 in a 12 square degree area centred on the Fornax cluster. The ...

An Hα Survey of the Galactic Plane
We describe a major new Anglo-Australian proposal for a U.K. Schmidt Telescope (UKST) Hα survey of the Southern Galactic plane, Magellanic clouds and selected regions. The agreed survey will use a new 12 × 12 inc...

Measures of Galactic and Intergalactic Mass in Clusters
If a galaxy cluster’s X-ray gas distribution follows an isothermal poly-tropic β model, we may write the electron radial density distribution as; n e = n ...

Interacting elliptical galaxies as hosts of intermediate-redshift quasars
QUASARS are the most luminous objects in the Universe. It has been speculated that they are the visible evidence for accretion of gas onto supermassive black holes that reside at the centres of host galaxies. ...

Surveys of Low Surface Brightness Galaxies with 4415 Films
During the past few years there have been a number of surveys for low surface brightness galaxies (LSBGs). Searches using both photographic and CCD data have shown that LSBGs are actually very numerous (Impey,...

Automatic Detection of Low-Surface Brightness Galaxies on Digital Images
Algorithms employed to identify and quantify images on digitised images mostly employ contiguous-pixel (e.g. PISA [based on APM software by Irwin 1985]) or median-filtering techniques and thus miss extended lo...

Use of Kodak Tech-Pan Film at the Ukstu
Kodak Technical Pan (Tech Pan) emulsion is an extremely fine grained, high resolution, pan chromatic negative film with extended red sensitivity. It has been produced under this name since about 1980 (Kodak P-...

Recent Results from Low Surface Brightness Galaxy Surveys
In recent years, especially following the work of Binggeli et al. (1985) on the Virgo Cluster, there has been a great surge of interest in low surface brightness galaxies (LSBGs). One of the most important que...

The Hitchhiker Parallel Camera and Studies of Faint Galaxies
The Hitchhiker camera performs CCD imaging of an off-axis field on a 4 m telescope in parallel with the normal on-axis scientific programmes. Using a dichroic beam splitter it images in two colours simultaneou...

Surface brightness bias in galaxy catalogues; distance effects
We have investigated the apparent variation of the surface brightness distribution of disc galaxies with distance within three different samples 1) a diameter limited sample of ESO catalogue galaxies in the di...

Normal Surface Brightness Dwarf Galaxies in the Fornax Cluster
There are strong selection effects in favour of selecting galaxies of certain surface brightnesses (Disney & Phillipps 1983; Davies 1990), and against finding galaxies of other surface brightnesses. Both low a...

Surveys for Low Surface Brightness Galaxies
In recent years it has become apparent that there exist substantial numbers of Low Surface Brightness Galaxies (LSBGs) in clusters. These were not seen in earlier surveys because of technical limitations and s...

Are Spiral Galaxies Optically Thick?
We have re-examined the classical optical evidence for the traditional view that spiral discs are optically thin and find it to be highly model dependent and unconvincing. We find that the data can be equally ...

The surface brightness of IRAS galaxies
Using IRAS measurements, we find positive correlations between both the infrared to optical flux ratio (L FIR/L B) and infrared colour temperature (L 60/L 100) with optical surface brightness. These correlations ...

Galaxy Correlations as a Function of Luminosity
It is difficult to determine the variation of galaxy clustering as a function of luminosity from normal 3-D redshift surveys because such surveys of galaxy distances contain few intrinsically faint objects (th...

Galactic γ and radio synchrotron radiation
The galactic γ-radiation and radio synchrotron radiation contains information on the distribution of cosmic-ray particles, magnetic field and gas throughout the Galaxy. We report here a new all-sky survey of 4...

The Large-Scale Distribution of Synchrotron Emissivity in the Galaxy
The all-sky radio continuum map at 408 MHz presented at this symposium by Haslam et al. can be interpreted in terms of the large-scale 3-dimensional distribution of synchrotron emissivity in the Galaxy when du...

The Field Luminosity Function and Nearby Groups of Galaxies
We have assembled a catalog of radial velocities and magnitudes on a homogeneous system (the corrected Harvard, B(o) magnitudes of de Vaucouleurs) for over 4000 galaxies. Using this catalog, we have compiled a...
