Physics of Neutron Star Kicks
Dong Lai
It is no longer necessary to `sell' the idea of pulsar kicks, the notion that neutron stars receive a large velocity (a few hundred to a thousand km s) at birth. However, th…
Two-body B Meson Decays to eta and eta': Observation of B->eta K*
The CLEO Collaboration, S. J. Richichi
In a sample of 19 million produced B mesons, we have observed the decays B -> eta K* and improved our previous measurements of B -> eta'K. The branching fractions we measure for th…
Pattern formation in inclined layer convection
Karen E. Daniels, Eberhard Bodenschatz
We report experiments on thermally driven convection in an inclined layer of large aspect ratio in a fluid of Prandtl number . We observed a number of new nonlinear, mo…
A VLA Search for the Geminga Pulsar: A Bayesian Limit on a Scintillating Source
M. A. McLaughlin, J. M. Cordes, T. H. Hankins +1
We derive an upper limit of 3 mJy (95% confidence) for the flux density at 317 MHz of the Geminga pulsar (J0633+1746). Our results are based on 7 hours of fast-sampled VLA data, wh…
Can the post-Newtonian gravitational waveform of an inspiraling binary be improved by solving the energy balance equation numerically?
Wolfgang Tichy, Eanna E. Flanagan, Eric Poisson
The detection of gravitational waves from inspiraling compact binaries using matched filtering depends crucially on the availability of accurate template waveforms. We determine wh…
Particle Systems with Stochastic Passing
I. Ispolatov, P. L. Krapivsky
We study a system of particles moving on a line in the same direction. Passing is allowed and when a fast particle overtakes a slow particle, it acquires a new velocity drawn from…
Semileptonic B Decays from CLEO
Karl M. Ecklund
I report results in semileptonic decays of B mesons from the CLEO collaboration, with a focus on recent results. Results for exclusive reconstruction of B -> D* l nu, B -> D l nu a…
A Search for OH Megamasers at z > 0.1: Preliminary Results
J. Darling, R. Giovanelli
We report the discovery of 11 OH megamasers and one OH absorber, along with upper limits on the OH luminosity of 53 other luminous infrared galaxies at z > 0.1. The new megamasers…
The Exact S-Matrix for an osp(2|2) Disordered System
Z. S. Bassi, A. LeClair
We study a two-dimensional disordered system consisting of Dirac fermions coupled to a scalar potential. This model is closely related to a more general disordered system that has…
Low temperature acoustic properties of amorphous silica and the Tunneling Model
EunJoo Thompson, G. Lawes, J. M. Parpia +1
Internal friction and speed of sound of a-SiO(2) was measured above 6 mK using a torsional oscillator at 90 kHz, controlling for thermal decoupling, non-linear effects, and clampin…
Extragalactic Spectroscopy with SIRTF/IRS
B. Brandl, V. Charmandaris, K. Uchida +1
The Infrared Spectrograph (IRS) is one of the three instruments on board the Space Infrared Telescope Facility (SIRTF) to be launched in December 2001. The IRS will provide high re…
Ab initio study of magnetic structure and chemical reactivity of Cr2O3 and its (0001) surface
J. A. Cline, A. A. Rigos, T. A. Arias
We present the first ab initio density functional theory study of the oxygen-terminated Cr2O3 (0001) surface within the local spin-density approximation (LSDA). We find that spin p…
Exact solution of a Z(4) gauge Potts model on planar lattices
N. S. Ananikian, R. G. Ghulghazaryan, N. Sh. Izmailian +1
The exact solution of a general Z(4) gauge Potts model with a single and double plaquette representation of the action is found on a subspace of gauge-coupling parameters on the sq…
Smoke in the "Smoke Rings": ISO Observations of Dust in Collisional Ring Galaxies
P. N. Appleton, V. Charmandaris, C. Horellou +2
Collisional ring galaxies probably result from a head-on collision between a compact companion galaxy and a gas-rich disk system. We present a review of the discovery of warm dust…
Study of Exclusive Radiative B Meson Decays
CLEO Collaboration
We have investigated exclusive, radiative B meson decays to charmless mesons (ρ, ω, ϕ, K^*(892), K^*_2(1430)) in 9.7\times 10^6 BBbar decays accumulated with the CLEO detector. The…
Cox's Theorem Revisited
Joseph Y. Halpern
The assumptions needed to prove Cox's Theorem are discussed and examined. Various sets of assumptions under which a Cox-style theorem can be proved are provided, although all are r…
The Gamma Ray Pulsar Population
M. A. McLaughlin, J. M. Cordes
We apply a likelihood analysis to pulsar detections, pulsar upper limits, and diffuse background measurements from the OSSE and EGRET instruments on the Compton Gamma Ray Observato…
R-Mode Oscillations and Spindown of Young Rotating Magnetic Neutron Stars
Wynn C. G. Ho, Dong Lai
Recent work has shown that a young, rapidly rotating neutron star loses angular momentum to gravitational waves generated by unstable r-mode oscillations. We study the spin evoluti…
Correlated sampling in quantum Monte Carlo: a route to forces
Claudia Filippi, C. J. Umrigar
In order to find the equilibrium geometries of molecules and solids and to perform ab initio molecular dynamics, it is necessary to calculate the forces on the nuclei. We present a…
Internal Friction of Amorphous Silicon in a Magnetic Field
T. H. Metcalf, Xiao Liu, R. O. Pohl
The internal friction of e-beam amorphous silicon was measured in a magnetic field between 0 and 6 T, from 1.5-20 K, and was found to be independent of the field to better than 8%.…
Spectral Methods for Numerical Relativity. The Initial Data Problem
Lawrence E. Kidder, Lee Samuel Finn
Numerical relativity has traditionally been pursued via finite differencing. Here we explore pseudospectral collocation (PSC) as an alternative to finite differencing, focusing par…
