Cosmological Parameters and Hyper-Parameters: The Hubble Constant from Boomerang and Maxima
Ofer Lahav
We generalise the procedure for joint estimation of cosmological parameters to allow freedom in the relative weights of various probes. This is done by including in the joint Likel…
Long-term Optical Variability of Radio-Selected Quasars from the FIRST Survey
David J. Helfand, Remington P. S. Stone, Beth Willman +5
We have obtained single-epoch optical photometry for 201 quasars, taken from the FIRST Bright Quasar Survey, which span a wide range in radio loudness. Comparison with the magnitud…
Strongly coupled Coulomb and nuclear plasma in inner crusts of neutron stars
D. G. Yakovlev, O. Y. Gnedin, A. Y. Potekhin
Matter of subnuclear density in the inner crusts of neutron stars consists of neutron-rich atomic nuclei immersed in strongly degenerate relativistic gas of electrons and strongly…
Evolution of Black Holes in Brans-Dicke Cosmology
Nobuyuki Sakai, John D. Barrow
We consider a modified ``Swiss cheese'' model in the Brans-Dicke theory, and discuss the evolution of black holes in the expanding universe. We define the black hole radius by the…
The Effect of Helicity on the Effective Diffusivity for Incompressible Random Flows
D. S. Dean, I. T. Drummond, R. R. Horgan
The advection of a passive scalar by a quenched (frozen) incompressible velocity field is studied by extensive high precision numerical simulation and various approximation schemes…
Compression and Classification Methods for Galaxy Spectra in Large Redshift Surveys
Ofer Lahav
Methods for compression and classification of galaxy spectra, which are useful for large galaxy redshift surveys (such as the SDSS, 2dF, 6dF and VIRMOS), are reviewed. In particula…
Constraining Isocurvature Perturbations with CMB Polarization
M Bucher, K Moodley, N Turok
The role of cosmic microwave background (CMB) polarisation data in constraining the presence of primordial isocurvature modes is examined. While the MAP satellite mission will be u…
Polytetrahedral Clusters
Jonathan Doye, David Wales
By studying the structures of clusters bound by a model potential that favours polytetrahedral order, we find a previously unknown series of `magic numbers' (i.e. sizes of special…
Final Results from the Hubble Space Telescope Key Project to Measure the Hubble Constant
W. L. Freedman, B. F. Madore, B. K. Gibson +12
We present here the final results of the Hubble Space Telescope Key Project to measure the Hubble constant. We summarize our method, the results and the uncertainties, tabulate our…
Ultraviolet Line Spectra of Metal-Poor Star-Forming Galaxies
Claus Leitherer, Joao Leao, Tim Heckman +3
We present synthetic ultraviolet spectra of metal-poor star-forming galaxies which were calculated with the Starburst99 package. A new spectral library was generated from HST obser…
Discriminating weak lensing from intrinsic spin correlations using the curl-gradient decomposition
Robert G. Crittenden, Priyamvada Natarajan, Ue-Li Pen +1
The distortion field defined by the ellipticities of galaxy shapes projected on the sky can be uniquely decomposed into a gradient and a curl component. If the observed ellipticiti…
Tunable-filter imaging of quasar fields at z~1. I. A cluster around MRC B0450-221
Joanne C. Baker, Richard W. Hunstead, Malcolm N. Bremer +3
Using a combination of multicolour broad- and narrow-band imaging techniques and follow-up spectroscopy, we have detected an overdensity of galaxies in the field of quasar MRC B045…
Cosmological Perturbations in Brane Worlds: Brane Bending and Anisotropic Stresses
M. Dorca, C. van de Bruck
Using a metric-based formalism to treat cosmological perturbations, we discuss the connection between anisotropic stress on the brane and brane bending. First we discuss gauge-tran…
Discrete structures in gravity
Tullio Regge, Ruth M. Williams
Discrete approaches to gravity, both classical and quantum, are reviewed briefly, with emphasis on the method using piecewise-linear spaces. Models of 3-dimensional quantum gravity…
CMB anisotropy from spatial correlations of clusters of galaxies
Eiichiro Komatsu, Tetsu Kitayama, Alexandre Refregier +2
The SZ effect from clusters of galaxies is a dominant source of secondary CMB anisotropy in the low-redshift universe. We present analytic predictions for the CMB power spectrum fr…
Accretion onto nearby supermassive black holes: Chandra constraints on the dominant cluster galaxy NGC 6166
T. Di Matteo, R. M. Johnstone, S. W. Allen +1
Chandra observations of low-luminosity supermassive black holes in nearby elliptical galaxies provide tight limits on both their nuclear luminosities and on their Bondi accretion r…
Superconductivity on the threshold of magnetism in CePd2Si2 and CeIn3
F. M. Grosche, I. R. Walker, S. R. Julian +4
The magnetic ordering temperature of some rare earth based heavy fermion compounds is strongly pressure-dependent and can be completely suppressed at a critical pressure, p, ma…
Predicting the peculiar velocities of nearby PSC-z galaxies using the Least Action Principle
J. Sharpe, M. Rowan-Robinson, A. Canavezes +12
We use the Least Action Principle to predict the peculiar velocities of PSC-z galaxies inside \km. Linear theory is used to account for tidal effects to \km, and…
Numerical and Analytical Predictions for the Large-Scale Sunyaev-Zel'dovich Effect
Alexandre Refregier, Romain Teyssier
The hot gas embedded in the large-scale structures in the Universe produces secondary fluctuations in the Cosmic Microwave Background (CMB). Because it is proportional to the gas p…
Solitonic fullerene structures in light atomic nuclei
R. A. Battye, P. M. Sutcliffe
The Skyrme model is a classical field theory which has topological soliton solutions. These solitons are candidates for describing nuclei, with an identification between the number…
Taming the supergravity description of non-BPS D-branes: the D/Dbar solution
P. Bain
We obtain the supergravity solution which describes a bound state of D-string/anti-D-string pairs attached to different fixed planes of an orbifold, in type IIB string theory compa…
Multi-Domain Walls in Massive Supersymmetric Sigma-Models
Jerome P. Gauntlett, David Tong, Paul K. Townsend
Massive maximally-supersymmetric sigma models are shown to exhibit multiple static kink-domain wall solutions that preserve 1/2 of the supersymmetry. The kink moduli space admits a…
The Heterotic Dyonic Instanton
E. Eyras, P. K. Townsend, M. Zamaklar
The static Yang-Mills-Higgs dyonic instanton is shown to have a non-vanishing, but anti-self-dual, angular momentum 2-form with skew eigenvalues equal to the electric charge; for l…
Brane World Sum Rules
Gary Gibbons, Renata Kallosh, Andrei Linde
A set of consistency conditions is derived from Einstein equations for brane world scenarios with a spatially periodic internal space. In particular, the sum of the total tension o…
