The Chemical Evolution of the Universe
A. C. Baker, G. P. Mathlin, D. K. Churches +1
We are encouraged by the improving abundance measurements for quasar damped absorption line systems to start a new study of galaxy chemical evolution from high to low redshifts. Ou…
Compactly supported wavelets and representations of the Cuntz relations
Ola Bratteli, David E. Evans, Palle E. T. Jorgensen
We study the harmonic analysis of the quadrature mirror filters coming from multiresolution wavelet analysis of compactly supported wavelets. It is known that those of these wavele…
Deep 12 micron ISO Survey
D. L. Clements
I present results from a deep 12 micron extragalactic survey conducted with the ISOCAM instrument. The survey covers about 0.1 sq. deg. in four fields and reaches a 5 sigma flux li…
SCUBA observations of NGC 6946
S. Bianchi, J. Davies, P. Alton +2
We present sub-millimetre images of the spiral galaxy NGC 6946 at 450 and 850 um. The observations have been carried out using the scan/map imaging mode of the Sub-millimetre Commo…
Modular Invariants from Subfactors: Type I Coupling Matrices and Intermediate Subfactors
J. Böckenhauer, D. E. Evans
A braided subfactor determines a coupling matrix Z which commutes with the S- and T-matrices arising from the braiding. Such a coupling matrix is not necessarily of "type I", i.e.…
Getting Ready for GEO600 Data
Bernard F Schutz
Data of good quality is expected from a number of gravitational wave detectors within the next two years. One of these, GEO600, has special capabilities, such as narrow-band operat…
ISO observations of spirals: modelling the FIR emission
Simone Bianchi, Paul B. Alton, Jonathan I. Davies
ISO observations at 200 micron have modified our view of the dust component in spiral galaxies. For a sample of seven resolved spirals we have retrieved a mean temperature of 20K,…
Far Infrared Loud Quasars 1: Disturbed and Quiescent Quasars in the PG Survey
D. L. Clements
We use host galaxy imaging studies of the PG Quasar survey to compare the far-infrared (FIR) properties of quasars with disturbed and undisturbed host galaxies. By using survival a…
Effects of Clumping on the Observed Properties of Dusty Galaxies
Simone Bianchi, Andrea Ferrara, Jon Davies +1
We present Monte Carlo radiative transfer simulations for spiral galaxies modelled as a stellar disk and a two-phase clumpy dust distribution. We divide the volume occupied by the…
A superradiance resonance cavity outside rapidly rotating black holes
Nils Andersson, Kostas Glampedakis
We discuss the late-time behaviour of a dynamically perturbed Kerr black hole. We present analytic results for near extreme Kerr black holes that show that the large number of virt…
Photometric Redshifts in Hubble Deep Field South
D. L. Clements
We apply both a traditional `dropout' approach and a photometric redshift estimation technique to the Hubble Deep Field South data. We give a list of dropout selected z3 obje…
A Far-Infrared Survey of Molecular Cloud Cores
N. E. Jessop, D. Ward-Thompson
We present a catalogue of molecular cloud cores drawn from high latitude, medium opacity clouds, using the all-sky IRAS Sky Survey Atlas (ISSA) images at 60 and 100~m. The typic…
The Energy-Momentum Tensor for the Gravitational Field
S V Babak, L P Grishchuk
The search for the gravitational energy-momentum tensor is often qualified as an attempt of looking for ``the right answer to the wrong question''. This position does not seem conv…
Topological Entropy for the Canonical Endomorphism of Cuntz-Krieger Algebras
Florin P. Boca, Paul Goldstein
It is shown that Voiculescu's toplogical entropy for the canonical endomorphism of a simple Cuntz-Krieger algebra O_A equals the logarithm of the spectral radius of A.
Candidate High Redshift and Primeval Galaxies in Hubble Deep Field South
D. L. Clements, S. A. Eales, A. C. Baker
We present the results of colour selection of candidate high redshift galaxies in Hubble Deep Field South (HDF-S) using the Lyman dropout scheme. The HDF-S data we discuss were tak…
Limits on the star formation rates of z>2 damped Ly-alpha systems from H-alpha spectroscopy
Andrew J. Bunker, Stephen J. Warren, D. L. Clements +2
We present the results of a long-slit K-band spectroscopic search for H-alpha emission from eight damped Ly-alpha absorbers (DLAs) at z>2 with the goal of measuring the star-format…
Upper limits on K-band polarization in three high-redshift radio galaxies: LBDS 53W091, 3C 441 and MRC 0156-252
G. Leyshon, J. S. Dunlop, Stephen A. Eales
We present the results of K-band imaging polarimetry of three radio galaxies, including the very red and apparently old z=1.55 galaxy 53W091. We find weak evidence for polarization…
Evidence for Filamentarity in the Las Campanas Redshift Survey
Somnath Bharadwaj, Varun Sahni, B. S. Sathyaprakash +2
We apply Shapefinders, statistical measures of `shape' constructed from two dimensional partial Minkowski functionals, to study the degree of filamentarity in the Las Campanas Reds…
From Pre-Stellar Cores to Protostars: The Initial Conditions of Star Formation
Philippe Andre, Derek Ward-Thompson, Mary Barsony
The last decade has witnessed significant advances in our observational understanding of the earliest stages of low-mass star formation. The advent of sensitive receivers on large…
Observational Limit on Gravitational Waves from Binary Neutron Stars in the Galaxy
B. Allen, J. K. Blackburn, P. R. Brady +15
Using optimal matched filtering, we search 25 hours of data from the LIGO 40-meter prototype laser interferometric gravitational-wave detector for gravitational-wave chirps emitted…
The Morphologically Divided Redshift Distribution of Faint Galaxies
M. Im, R. E. Griffiths, A. Naim +4
We have constructed a morphologically divided redshift distribution of faint field galaxies using a statistically unbiased sample of 196 galaxies brighter than I = 21.5 for which d…
The Canada-UK Deep Sub-Millimeter Survey II: First identifications, redshifts and implications for galaxy evolution
Simon J. Lilly, Stephen A. Eales, Walter K. P. Gear +5
Identifications are sought for 12 sub-mm sources detected by Eales et al (1998). Six are securely identified, two have probable identifications and four remain unidentified with I_…
