X-ray Emission from the Host Clusters of Powerful AGN
Patrick B. Hall, Erica Ellingson, Richard F. Green
(Abridged) We report the detection of X-ray emission from the host cluster of the radio-quiet quasar H1821+643 with the ROSAT HRI, and the non-detection of the host cluster of the…
Lyman Alpha Forest towards B2 1225+317
Pushpa Khare, R. Srianand, D. G. York +4
We present observations of the Lyman alpha forest towards B2 1225+317 taken at a resolution of 18 km/s. A clean sample of Lyman alpha forest lines is extracted after a careful prof…
A survey for large image-separation lensed quasars
Dan Maoz, Hans-Walter Rix, Avishay Gal-Yam +1
The statistics of gravitationally lensed quasars with multiple images in the 0.1''-7'' range have been measured in various surveys. Little is known, however, about lensed-quasar st…
Search for Diphoton Events with Large Missing Transverse Energy in proton-antiproton collisions at sqrt(s) = 1.8 TeV
S. Abachi
A search for signals of new physics has been carried out in the channel p pbar -> gamma gamma + ETmiss. This signature is expected in various recently proposed supersymmetric (SUSY…
Search for Top Squark Pair Production in the Dielectron Channel
D0 Collaboration, S. Abachi
This report describes the first search for top squark pair production in the channel stop_1 stopbar_1 -> b bbar chargino_1 chargino_1 -> ee+jets+MEt using 74.9 +- 8.9 pb^-1 of data…
Atomic Carbon in M82: Physical conditions derived from simultaneous observations of the [CI] fine structure submillimeter wave transitions
J. Stutzki, U. U. Graf, S. Haas +10
We report the first extragalactic detection of the neutral carbon [CI] 3P2-3P1 fine structure line at 809 GHz. The line was observed towards M82 simultaneously with the 3P1-3P0 lin…
The metastate approach to thermodynamic chaos
C. M. Newman, D. L. Stein
In realistic disordered systems, such as the Edwards-Anderson (EA) spin glass, no order parameter, such as the Parisi overlap distribution, can be both translation-invariant and no…
Controlling extended systems with spatially filtered, time-delayed feedback
Michael E. Bleich, David Hochheiser, Jerome V. Moloney +1
We investigate a control technique for spatially extended systems combining spatial filtering with a previously studied form of time-delay feedback. The scheme is naturally suited…
Limits on Anomalous Couplings from Events at TeV
The DZero Collaboration, S. Abachi
We have measured the gauge boson coupling parameters using () events at TeV. The data, corresponding to an integrated luminosi…
Collapses and Revivals of Collective Excitations in Trapped Bose Condensates
R. Graham, D. F. Walls, M. J. Collett +2
We present a quantum theory of low-lying excitations in a trapped Bose condensate with finite particle numbers. We find that even at zero temperature condensate number fluctuations…
Which Chiral Symmetry is Restored in High Temperature QCD?
Claude Bernard, Tom Blum, Carleton DeTar +7
Sigma models for the high temperature phase transition in quantum chromodynamics (QCD) suggest that at high temperature the SU(N_f) x SU(N_f) chiral symmetry becomes exact, but the…
Collapses and revivals in the interference between two Bose-Einstein condensates formed in small atomic samples
E. M. Wright, T. Wong, M. J. Collett +2
We investigate the quantum interference between two Bose-Einstein condensates formed in small atomic samples composed of a few thousand atoms both by imposing Bose broken gauge sym…
The Physics of Type Ia Supernova Lightcurves: I. Opacity and Diffusion
Philip A. Pinto, Ronald G. Eastman
We examine the basic physics of type Ia supernova (SNe Ia) light curves with a view toward interpreting the relations between peak luminosity, peak width, and late-time slope in te…
Determination of the Longitudinal Proton Structure Function F_L(x,Q^2) at Low x
C. Adloff
A measurement of the inclusive cross section for the deep-inelastic scattering of positrons off protons at HERA is presented at momentum transfers and…
Accretion Disk Evolution With Wind Infall I. General Solution and Application to Sgr A*
Heino Falcke, Fulvio Melia
The evolution of an accretion disk can be influenced significantly by the deposition of mass and angular momentum by an infalling Bondi-Hoyle wind. Such a mass influx impacts the l…
Where Does Dark Matter Become Important in Elliptical Galaxies?
H. -W. Rix
Recent results from gravitational lensing are combined with new modeling of the stellar velocity distributions in nearby galaxies to probe the connection between the luminous and t…
A Universal Density Profile from Hierarchical Clustering
Julio F. Navarro, Carlos S. Frenk, Simon D. M. White
We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have…
Cosmological Constraints from Rotation Curves of Disk Galaxies
Julio F. Navarro
High-resolution N--body simulations show a remarkable similarity in the structure of dark matter halos formed through dissipationless hierarchical clustering. Independent of halo m…
The Cores of Dwarf Galaxy Halos
Julio F. Navarro, Vincent R. Eke, Carlos S. Frenk
We use N-body simulations to examine the effects of mass outflows on the density profiles of cold dark matter (CDM) halos surrounding dwarf galaxies. In particular, we investigate…
Coordinates on Schubert cells, Kostant's harmonic forms, and the Bruhat-Poisson structure on
Jiang-Hua Lu
We relate Kostant's theorem on the cohomology of a flag manifold with the geometry of the Bruhat-Poisson structure. We express Kostant's harmonic forms in terms of the moment…
