New M-theory Backgrounds with Frozen Moduli
Michael Dine, Eva Silverstein
We propose examples, which involve orbifolds by elements of the U-duality group, with M-theory moduli fixed at the eleven-dimensional Planck scale. We begin by reviewing asymmetric…
Branching Fractions for D0 -> K+K- and D0 -> pi+pi-, and a Search for CP Violation in D0 Decays
The Fermilab E791 Collaboration, E. M. Aitala
Using the large hadroproduced charm sample collected in experiment E791 at Fermilab, we have measured ratios of branching fractions for the two-body singly-Cabibbo-suppressed charg…
Optical Spectroscopy of Galactic Cirrus Clouds: Extended Red Emission in the Diffuse Interstellar Medium
Arpad Szomoru, Puragra Guhathakurta
We present initial results from the first optical spectroscopic survey of high latitude Galactic cirrus clouds. The observed shape of the cirrus spectrum does not agree with that o…
Globular Cluster Halos around the brightest Fornax Ellipticals
Markus Kissler-Patig
We compare the properties of the globular clusters around NGC 1399, NGC 1404 and NGC 1380, the three brightest early-type galaxies in the center of the Fornax galaxy cluster. The g…
The HST Key Project on the Extragalactic Distance Scale XIII. The Metallicity Dependence of the Cepheid Distance Scale
R. Kennicutt, P. Stetson, A. Saha +22
Uncertainty in the metal abundance dependence of the Cepheid variable period- luminosity (PL) relation remains one of the outstanding sources of systematic error in the extragalact…
``E+A'' Galaxies: Environment and Evolution
Ann I. Zabludoff
One important approach to the study of galaxy evolution is to identify those galaxies whose spectral and/or morphological characteristics suggest that they are in transition. For e…
CDM-Variant Cosmological Models - I: Simulations and Preliminary Comparisons
Michael A. K. Gross, Rachel S. Somerville, Joel R. Primack +2
We present two matched sets of five simulations each, covering five presently favored simple modifications to the standard cold dark matter (CDM) scenario. One simulation suite, wi…
Implications of Spikes in the Redshift Distribution of Galaxies
Risa H. Wechsler, Michael A. K. Gross, Joel R. Primack +2
We address the high peaks found by Steidel et al (1997) in the redshift distribution of ``Lyman-break'' objects (LBOs) at redshift z~3. The highest spike represents a relative over…
Relative Sizes of X-ray and Optical Images of Elliptical Galaxies; Correlation with X-ray Luminosity
William G. Mathews, Fabrizio Brighenti
Optical parameters of elliptical galaxies are tightly correlated, but their x-ray parameters vary widely. The x-ray luminosity L_x ranges over more than an order of magnitude for e…
Phase diagrams, critical and multicritical behavior of hard-core Bose-Hubbard models
C. Pich, E. Frey
We determine the zero-temperature phase diagram of the hard-core Bose-Hubbard model on a square lattice by mean-field theory supplemented by a linear spin-wave analysis. Due to the…
Oscillations in solar-type stars tidally induced by orbiting planets
C. Terquem, J. C. B. Papaloizou, R. P. Nelson +1
We examine the effect of dynamical tides raised by a companion on a solar-type star. In these binaries, gravity or g mode oscillations are excited by the companion in the radiative…
Polarised Quark Distributions in the Nucleon from Semi-Inclusive Spin Asymmetries
Spin Muon Collaboration
We present a measurement of semi-inclusive spin asymmetries for positively and negatively charged hadrons from deep inelastic scattering of polarised muons on polarised protons and…
Abundance Profiles in Low-Mass Galaxies
Henry A. Kobulnicky
The nitrogen and oxygen abundances in the warm ionized gas of low-mass, metal-poor galaxies appear surprisingly homogeneous considering the prevalence of large HII regions, which c…
Hot Gas and Halos in Elliptical Galaxies
William G. Mathews, Fabrizio Brighenti
We review recent progress in understanding the evolution of hot interstellar gas in the halos of elliptical galaxies. Non-homologous variations in the physical size of the hot gas…
Rank one lattice type vertex operator algebras and their automorphism groups
Chongying Dong, Robert L. Griess
Let L be a positive definite even lattice of rank one and V_L^+ be the fixed points of the lattice VOA V_L associated to L under an automorphism of V_L lifting the -1$ isometry of…
A comparative modeling of supernova 1993J
S. I. Blinnikov, R. Eastman, O. S. Bartunov +2
The light curve of Supernova (SN) 1993J is calculated using two approaches to radiation transport as exemplified by the two computer codes, STELLA and EDDINGTON. Particular attenti…
How to Plant a Merger Tree
Rachel S. Somerville, Tsafrir S. Kolatt
We investigate several approaches for constructing Monte Carlo realizations of the merging history of virialized dark matter halos (``merger trees'') using the extended Press-Schec…
Multigraviton Scattering in the Matrix Model
M. Dine, A. Rajaraman
We consider scattering processes in the matrix model with three incoming and three outgoing gravitons. We find a discrepancy between the amplitude calculated from the matrix model…
Updated measurement of the tau lepton lifetime
The ALEPH Collaboration
A new measurement of the mean lifetime of the tau lepton is presented. Three different analysis methods are applied to a sample of 90000 tau pairs, collected in 1993 and 1994 with…
The Thermal Evolution of Ultramagnetized Neutron Stars
Jeremy S. Heyl, Lars Hernquist
Using recently calculated analytic and numerical models for the thermal structure of ultramagnetized neutron stars, we estimate the effects that ultrastrong magnetic fields $B \ge…
Smooth Particle Hydrodynamics: Models, Applications, and Enabling Technologies
Piet Hut, Lars Hernquist, George Lake +3
We present the results from a two-day study in which we discussed various implementations of Smooth Particle Hydrodynamics (SPH), one of the leading methods used across a variety o…
Recent X-ray Observations and the Evolution of Hot Gas in Elliptical Galaxies: Evidence for Circumgalactic Gas
Fabrizio Brighenti, William G. Mathews
X-ray emitting gaseous halos, such as that in elliptical galaxies like NGC 4472, cannot have been produced solely from gas expelled from galactic stars. In traditional models for t…
Supersymmetry Breaking with Periodic Potentials
G. Dunne, J. Mannix
We discuss supersymmetry breaking in some supersymmetric quantum mechanical models with periodic potentials. The sensitivity to the parameters appearing in the superpotential is mo…

ALEPH Collaboration
Searches for supersymmetric particles in channels with one or more photons and missing energy have been performed with data collected by the ALEPH detector at LEP. The data consist…
