A G_2 Unification of the Deformed and Resolved Conifolds
M. Cvetic, G. W. Gibbons, H. Lu +1
We find general first-order equations for G_2 metrics of cohomogeneity one with S^3\times S^3 principal orbits. These reduce in two special cases to previously-known systems of fir…
Observational Tests of FRW World Models
Ofer Lahav
Observational tests for the Cosmological Principle are reviewed. Assuming the FRW metric we then summarize estimates of cosmological parameters from various data sets, in particula…
Fluctuation induced hopping and spin polaron transport
L. G. L. Wegener, P. B. Littlewood
We study the motion of free magnetic polarons in a paramagnetic background of fluctuating local moments. The polaron can tunnel only to nearby regions of local moments when these f…
Peculiar velocity effects in high-resolution microwave background experiments
Anthony Challinor, Floor van Leeuwen
We investigate the impact of peculiar velocity effects due to the motion of the solar system relative to the microwave background (CMB) on high resolution CMB experiments. It is we…
A non-linear theory of vertical resonances in accretion discs
G. I. Ogilvie
An important and widely neglected aspect of the interaction between an accretion disc and a massive companion with a coplanar orbit is the vertical component of the tidal force. As…
Cosmological Perturbations Generated in the Colliding Bubble Braneworld Universe
Jose J. Blanco-Pillado, Martin Bucher
We compute the cosmological perturbations generated in the colliding bubble braneworld universe in which bubbles filled with five-dimensional anti-de Sitter space (AdS5)expanding w…
Search for Leptoquarks in Electron-Photon Scattering at sqrt(s_ee) up to 209 GeV at LEP
The OPAL collaboration, G. Abbiendi
Searches for first generation scalar and vector leptoquarks, and for squarks in R-parity violating SUSY models with the direct decay of the squark into Standard Model particles, ha…
Fractional D3-branes in diverse backgrounds
P. Bain
In the first part of this article, we find fractional D3-branes supergravity solutions on orientifolded C^2/Z_2 orbifolds of type IIB string theory. The one-loop corrected gauge co…
A-star envelopes: a test of local and non-local models of convection
F. Kupka, M. H. Montgomery
We present results of a fully non-local, compressible model of convection for A-star envelopes. This model quite naturally reproduces a variety of results from observations and num…
Tracing the Remnants of Powerful Quasars to Probe the IGM
Torsten A. Ensslin, Rashid A. Sunyaev, Markus Brueggen
Powerful quasars and radio galaxies are injecting large amounts of energy in the form of radio plasma into the inter-galactic medium (IGM). Once this nonthermal component of the IG…
M-theory Conifolds
M. Cvetic, G. W. Gibbons, H. Lu +1
Seven-manifolds of G_2 holonomy provide a bridge between M-theory and string theory, via Kaluza-Klein reduction to Calabi-Yau six-manifolds. We find first-order equations for a new…
Constraints on the mass-profile of the lens galaxy G2237+0305
J. S. B. Wyithe, E. Agol, E. L. Turner +1
Published parametric models of the Einstein Cross gravitational lens demonstrate that the image geometry can be reproduced by families of models. In particular, the slope of the ma…
Harmonic analysis of cosmic microwave background data II: from ring-sets to the sky
Anthony D. Challinor, Daniel J. Mortlock, Floor van Leeuwen +4
Despite the fact that the physics of the cosmic microwave background anisotropies is most naturally expressed in Fourier space, pixelised maps are almost always used in the analysi…
Harmonic analysis of cosmic microwave background data I: ring reductions and point-source catalogue
Floor van Leeuwen, Anthony D. Challinor, Daniel J. Mortlock +7
We present a harmonic model for the data analysis of an all-sky cosmic microwave background survey, such as Planck, where the survey is obtained through ring-scans of the sky. In t…
Comparison of variational real-space representations of the kinetic energy operator
Chris-Kriton Skylaris, Oswaldo Dieguez, Peter D. Haynes +1
We present a comparison of real-space methods based on regular grids for electronic structure calculations that are designed to have basis set variational properties, using as a re…
Supercooled Lennard-Jones Liquids and Glasses: a Kinetic Monte Carlo Approach
Javier Hernandez-Rojas, David J. Wales
A kinetic Monte Carlo (KMC) method is used to study the structural properties and dynamics of a supercooled binary Lennard-Jones liquid around the glass transition temperature. Thi…
Neutron Irradiation of MgB2 Bulk Superconductors
M. Eisterer, M. Zehetmayer, S. Toenies +5
Sintered samples of MgB2 were irradiated in a fission reactor. Defects in the bulk microstructure are produced during this process mainly by the 10B(n,a)7Li reaction while collisio…
Detecting the progenitors of core collapse supernovae
S. J. Smartt
The masses and the evolutionary states of the progenitors of core-collapse supernovae are not well constrained by direct observations. Stellar evolution theory generally predicts t…
Coarse-graining polymers as soft colloids
A. A. Louis, P. G. Bolhuis, R. Finken +3
We show how to coarse grain polymers in a good solvent as single particles, interacting with density-independent or density-dependent interactions. These interactions can be betwee…
The birth place of gamma-ray bursts: abundance gradients and constraints on progenitors
Enrico Ramirez-Ruiz, Davide Lazzati, Andrew W. Blain
The physics of gamma-ray bursts (GRBs) and their offsets from the centers of their host galaxies are used to investigate the evolutionary state of their progenitors, motivated by t…
Associated absorption in radio quasars. I. C IV absorption and the growth of radio sources
J. C. Baker, R. W. Hunstead, R. M. Athreya +4
We assess the global properties of associated C IV 1548,1550 absorption lines measured in the spectra of radio-loud quasars drawn from a near-complete, low-frequency selected sampl…
Initial low/hard state, multiple jet ejections and X-ray/radio correlations during the outburst of XTE J1859+226
C. Brocksopp, R. P. Fender, M. McCollough +8
We have studied the 1999 soft X-ray transient outburst of XTE J1859+226 at radio and X-ray wavelengths. The event was characterised by strong variability in the disc, corona and je…
The CORALS Survey II: Clues to Galaxy Clustering Around QSOs from z_abs ~ z_em Damped Lyman Alpha Systems
Sara L. Ellison, Lin Yan, Isobel M. Hook +3
We present a list of z_abs ~ z_em (Delta v < 3000 km/s) DLAs discovered during the CORALS survey for absorbers in a radio-selected QSO sample. On the assumption that z_abs ~ z_em D…
What does the local black hole mass distribution tell us about the evolution of the quasar luminosity function?
Luca Ciotti, Zoltan Haiman, Jeremiah P. Ostriker
We present a robust method to derive the duty cycle of QSO activity based on the empirical QSO luminosity function and on the present-day linear relation between the masses of supe…
