Griffiths Singularities in the Disordered Phase of a Quantum Ising Spin Glass

H. Rieger, A. P. Young

We study a model for a quantum Ising spin glass in two space dimensions by Monte Carlo simulations. In the disordered phase at , we find power law distributions of the local s…

Measurement of Dielectric Suppression of Bremsstrahlung

P. L. Anthony, R. Becker-Szendy, P. E. Bosted +8

In 1953, Ter-Mikaelian predicted that the bremsstrahlung of low energy photons in a medium is suppressed because of interactions between the produced photon and the electrons in th…

Autofib Redshift Survey - I. Evolution of the Galaxy Luminosity Function

Richard S. Ellis, Matthew Colless, Tom Broadhurst +2

We present a detailed determination of the restframe B-band galaxy luminosity function (LF) as a function of redshift and star formation activity from z=0 to z=0.75. The dataset us…

Gasdynamics and Starbursts in Major Mergers

Chris Mihos, Lars Hernquist

Using numerical simulation, we study the development of gaseous inflows and triggering of starburst activity in mergers of comparable-mass disk galaxies. In all encounters studied,…

Cluster Cores, Gravitational Lensing, and Cosmology

Ricardo A. Flores, Joel R. Primack

Many multiply--imaged quasars have been found over the years, but none so far with image separation in excess of $8\arcsec$. The absence of such large splittings has been used as a…

Study of Chirality in the Two-Dimensional XY Spin Glass

H. S. Bokil, A. P. Young

We study the chirality in the Villain form of the XY spin glass in two--dimensions by Monte Carlo simulations. We calculate the chiral-glass correlation length exponent $ν_{\script…

Small Scale Structure and High Redshift HI

David H. Weinberg, Lars Hernquist, Neal Katz +1

Cosmological simulations with gas dynamics suggest that the Lyman-alpha forest is produced mainly by "small scale structure" --- filaments and sheets that are the high redshift ana…

Strong Angular Clustering of Very Blue Galaxies: Evidence of a Low Redshift Population

Stephen D. Landy, Alexander S. Szalay, David C. Koo

We have studied galaxy two-point angular correlations as a function of color using 4-m plate photometry in two independent fields. Each field consists of over 2900 galaxies with ma…

Measurement of the Average -Hadron Lifetime in Decays

The SLD Collaboration

We report a measurement of the average -hadron lifetime using data collected with the SLD detector at the SLC in 1993. An inclusive analysis selected three-dimensional vertices…

The Geometric Phase in the Three-Body Problem

Richard Montgomery

Suppose that the initial triangle formed by the three moving masses of the three-body problem is similar to the triangle formed at some later time. We derive a simple integral form…

A Catalog of Digital Images of 113 Nearby Galaxies

Zsolt Frei, Puragra Guhathakurta, James E. Gunn +1

We present a digital catalog of images of 113 galaxies in this paper. These galaxies are all nearby, bright, large and well resolved. All images were recorded with charge coupled d…

Measurement of the proton and the deuteron structure functions F2p and F2d

The NMC Collaboration

The proton and deuteron structure functions F2p and F2d were measured in the kinematic range 0.006<x<0.6 and 0.5<Q^2<75 GeV^2, by inclusive deep inelastic muon scattering at 90, 12…

A Numerical Study of the Random Transverse-Field Ising Spin Chain

A. P. Young, H. Rieger

We study numerically the critical region and the disordered phase of the random transverse-field Ising chain. By using a mapping of Lieb, Schultz and Mattis to non-interacting ferm…
