Solitonic Black Holes in Gauged N=2 Supergravity
Alan Kostelecky, Malcolm Perry
A sequence of zero-temperature black-hole spacetimes with angular momentum and electric and magnetic charges is shown to exist in gauged supergravity. Stability of a subset o…
Detection of a Lyman-alpha Emission-Line Companion to the z=4.69 QSO BR1202-0725
Esther M. Hu, Richard G. McMahon, Eiichi Egami
We report the detection of a nearby emission-line companion to the z=4.695 quasar BR1202-0725. Deep narrow-band exposures on this field from the UH 2.2 m show a Ly alpha flux of 1.…
Retention Fractions for Globular Cluster Neutron Stars
G. A. Drukier
Fokker-Planck models are used to give estimates for the retention fractions for newly-born neutron stars in globular clusters as a function of kick velocity. These can be used to c…
Some Comments on Bosonisation and Biproducts
S. Majid
We collect here some less well-known results and formulae about the bosonisation construction which turns braided groups into quantum groups. We clarify the relation with biproduct…
Natural language processing: she needs something old and something new (maybe something borrowed and something blue, too)
Karen Sparck Jones
Given the present state of work in natural language processing, this address argues first, that advance in both science and applications requires a revival of concern about what la…
The Structure of Dark Matter Halos
Giuseppe Tormen
I use -body simulations to investigate the morphology and the dynamical evolution and properties of dark matter halos in clusters of galaxies. My sample consists of nine massive…
Large-Scale Structure at z~2.5
G. M. Williger, C. Hazard, J. A. Baldwin +1
We have made a statistically complete, unbiased survey of C IV systems toward a region of high QSO density near the South Galactic Pole using 25 lines of sight spanning …
A (1+1)-Dimensional Reduced Model of Mesons
F. Antonuccio, S. Dalley
We propose an extension of 't Hooft's large- light-front QCD in two dimensions to include helicity and physical gluon degrees of freedom, modelled on a classical dimensional r…
High Resolution Observations of the QSO BR1202-0725: Deuterium and Ionic Abundances at Redshifts Above z=4
E. J. Wampler, G. M. Williger, J. A. Baldwin +3
We present results from 12 km/s resolution echelle spectroscopy of the bright QSO BR1202-0725. A preliminary analysis shows that high metallicity narrow line absorption c…
Particle Motion in a Yang-Mills Field: Wong's Equations and Spin One-half Analogues
N Linden A J Macfarlane, J W van Holten
A complete, straightforward and natural Lagrangian description is given for the classical non-relativistic dynamics of a particle with colour or internal symmetry degrees of freedo…
A magnetic field diagnostic for sonoluminescence
Tom Chou, Eric G. Blackman
This study is motivated by the extraordinary process of single bubble sonoluminescence (SBSL), where an acoustically driven spherical shock is thought to power the emitted radiatio…
Analysis of the Arabic Broken Plural and Diminutive
George A. Kiraz
This paper demonstrates how the challenging problem of the Arabic broken plural and diminutive can be handled under a multi-tape two-level model, an extension to two-level morpholo…
Isolating the Foreground of the X-Ray Background
A. Refregier, D. J. Helfand, R. G. McMahon
The foreground component of the X-ray Background (XRB) can be studied by cross-correlating its intensity with galaxy catalogs. We computed the two-point cross-correlation function…
Magnetic braking of T Tauri stars
P. J. Armitage, C. J. Clarke
We construct models for the rotation rates of T Tauri stars whose spin is regulated by magnetic linkage between the star and a surrounding accretion disc. Our models utilise a time…
Reconnecting Magnetic Flux Tubes as a Source of In Situ Acceleration in Extragalactic Radio Sources
Eric G. Blackman
Many extended extragalactic radio sources require a local {\it in situ\/} acceleration mechanism for electrons, in part because the synchrotron lifetimes are shorter than the bulk…
Standard Model Higgs boson production and hard photon radiation in events at LEP II and Next Linear Collider
Stefano Moretti
We study at LEP II and Next Linear Collider energies Higgs production via the bremsstrahlung channel $e^+e^-\ar ZH$, with $Z\ar μ^+μ^-$ and $H\ar b\bar b$, and the corresponding ir…
Quasiclassical Dynamics in a Closed Quantum System
Adrian Kent
We consider Gell-Mann and Hartle's consistent histories formulation of quantum cosmology in the interpretation in which one history, chosen randomly according to the decoherence fu…
Adding Long Wavelength Modes to an -Body Simulation
Giuseppe Tormen, Edmund Bertschinger
We present a new method to add long wavelength power to an evolved -body simulation, making use of the Zel'dovich (1970) approximation to change positions and velocities of part…
The Current Star Formation Rate of the Local Universe
J. Gallego, J. Zamorano, A. Aragon-Salamanca +1
The Universidad Complutense de Madrid (UCM) Survey is a long-term project aiming at finding and analysing star-forming galaxies detected by their H emission in Schmidt objective…
Against the Wheeler-DeWitt equation
N. P. Landsman
The ADM approach to canonical general relativity combined with Dirac's method of quantizing constrained systems leads to the Wheeler-DeWitt equation. A number of mathematical as we…
Dynamo driven accretion discs and dwarf nova eruptions
P. J. Armitage, M. Livio, J. E. Pringle
We explore the consequences of a magnetic dynamo origin for the viscosity in accretion discs, for the structure and evolution of discs in dwarf nova systems. We propose that the ra…
Contributions of below--threshold decays to Higgs branching ratios: Erratum
S. Moretti, W. J. Stirling
In Ref.~\cite{paper} we calculated all the experimentally relevant branching ratios of the Higgs bosons of the Minimal Supersymmetric Standard Model, paying particular attention to…
Dynamical Breaking of CPT Symmetry in Defect Networks and Baryogenesis
Tomislav Prokopec, Robert Brandenberger, Anne C. Davis +1
Based on a study of {\it charge,} (C), {\it parity} (P) and {\it time reversal} (T) symmetries we show how a CP violating network of defects in the early Universe may bias baryon n…
The variable OVIII Warm Absorber in MCG-6-30-15
C. Otani, T. Kii, C. S. Reynolds +8
We present the results of a 4 day ASCA observation of the Seyfert galaxy MCG-6-30-15, focussing on the nature of the X-ray absorption by the warm absorber, characterizd by the K-ed…
