Environmental Effects on the Faint End of the Luminosity Function

S. Phillipps, J. B. Jones, R. M. Smith +2

Recent studies have demonstrated that many galaxy clusters have luminosity functions (LFs) which are steep at the faint end. However, it is equally clear that not all clusters have…

Modelling ISO Galaxy Counts with Luminosity and Merger Rate Evolution

Nathan Roche, Steve Eales

We model galaxy evolution in the 6.75 and 15 micron passbands of the ISO satellite, by combining models of galaxy evolution at optical wavelengths (which are consistent with the op…

15um ISO observations of a CFRS field: the cosmic SFR as derived from UV, optical, mid-IR and radio photometry

H. Flores, F. Hammer, T. Thuan +7

The CFRS 1452+52 field has been deeply imaged with the Infrared Space Observatory (ISO) using ISOCAM through the LW3 filter (12-18um). Careful data analysis and comparison to deep…

Found: High Surface Brightness Compact Galaxies

M. J. Drinkwater, S. Phillipps, J. B. Jones +5

We are using the 2dF spectrograph to make a survey of all objects (`stars' and `galaxies') in a 12 sq.deg region towards the Fornax cluster. We have discovered a population of comp…

Cosmological Evolution of the Submillimetre Luminosity of High-Redshift Radio Galaxies

D. H. Hughes, J. S. Dunlop, E. N. Archibald +2

A systematic survey measuring the submillimetre continuum luminosity in radio galaxies between redshifts z ~ 0.1 - 5 is currently in progress. The first results from observations w…

The Angular Correlation Function of K=19.5 Galaxies and the Detection of a Cluster at z=0.775

Nathan Roche, Steve Eales, Hans Hippelein +1

On five K-band Omega camera images, covering a total of 162.2 sq. arcmin to K=19.5, we investigate (i) the clustering environment of 5 radio galaxies at 0.7<z<0.8 and (ii) the gala…

Spiral Structure in IP Peg: Confronting Theory and Observations

Takuya Matsuda, Makoto Makita, Hiroshi Yukawa +1

The first convincing piece of evidence of spiral structure in the accretion disc in IP Pegasi was found by Steeghs et al. (1997). We performed two kinds of 2D hydrodynamic simulati…

The Canada-UK Deep Submillimetre Survey: First Submillimetre Images, the Source Counts, and Resolution of the Background

Stephen Eales, Simon Lilly, Walter Gear +5

We present the first results of a deep unbiased submillimetre survey carried out at 450 and 850 microns. We detected 12 sources at 850 microns, giving a surface density of sources…

SCUBA imaging of NGC 7331 dust ring

S. Bianchi, P. B. Alton, J. I. Davies +1

We present observations of the spiral galaxy NGC 7331 using the Sub-millimetre Common User Bolometer Array (SCUBA) on the James Clark Maxwell Telescope. We have detected a dust rin…

Morphology of Clusters and Superclusters in N-body simulations of Cosmological Gravitational Clustering

B. S. Sathyaprakash, Varun Sahni, Sergei F. Shandarin

We analyse shapes of overdense regions (clusters and superclusters) in controlled N-body simulations of gravitational clustering with power law initial spectra P(k) \propto k^n, n…

Filaments and Pancakes in the IRAS 1.2 Jy Redshift Catalogue

B. S. Sathyaprakash, Varun Sahni, Sergei F. Shandarin +1

We explore shapes of clusters and superclusters in the IRAS 1.2 Jy redshift survey with three reconstructions spanning the range β= 0.1, 0.5, 1.0, where β= Ω^{0.6}/b, b is the bias…

The Luminosity Distribution in Galaxy Clusters: A Dwarf Population - Density Relation?

S. Phillipps, S. P. Driver, W. J. Couch +1

Recent work suggests that rich clusters of galaxies commonly have large populations of dwarf (i.e. low luminosity) members, that is their luminosity function (LF) turns up to a ste…
