The Serendipitous Discovery of a Group or Cluster of young Galaxies at z=2.40 in Deep Hubble Space Telescope WFPC2 Images

Sebastian M. Pascarelle, Rogier A. Windhorst, Simon P. Driver +2

We report the serendipitous discovery of a group or cluster of young galaxies at 2.40 in a 24-orbit HST/WFPC2 exposure of the field around the weak radio galaxy 53W002. Po…

Photon Contribution to the ``Super-hard" Pomeron

Hung Jung Lu, Joseph Milana

It is shown that direct photons provide a leading twist mechanism for diffractive jet production in which the jets carry away all of the momentum lost by the proton. Two-photon pro…

The Nucleon Spectral Function at Finite Temperature and the Onset of Superfluidity in Nuclear Matter

T. Alm, G. Roepke, A. Schnell +2

Nucleon selfenergies and spectral functions are calculated at the saturation density of symmetric nuclear matter at finite temperatures. In particular, the behaviour of these quant…

Simulations of Galaxy Formation in Hierarchically Clustering Universes

Julio F. Navarro

I review the results of recent N--body/hydrodynamical simulations of the formation of galaxies in hierarchical universes, with special emphasis on the structure of dark matter halo…

Giant Planets at Small Orbital Distances

T. Guillot, A. Burrows, W. B. Hubbard +2

Using Doppler spectroscopy to detect the reflex motion of the nearby star, 51 Pegasi, Mayor \& Queloz (1995) claim to have discovered a giant planet in a 0.05-A.U., 4.23-day orbit.…

Pulsar Recoil and Gravitational Radiation due to Asymmetrical Stellar Collapse and Explosion

Adam Burrows, John Hayes

New data imply that the average velocity of radio pulsars is large \cite{hla93}. Under the assumption that these data imply that a pulsar is born with an ``intrinsic'' kick, we inv…

Domain Structure of a Disoriented Chiral Condensate From a Wavelet Perspective

Zheng Huang, Ina Sarcevic, Robert Thews +1

We present a novel method for studying the formation of a disoriented chiral condensate (DCC) in high-energy hadronic and heavy-ion collisions utilizing a discrete wavelet transfor…

Inhomogeneous universes in observational coordinates

Roy Maartens, Neil Humphreys, David Matravers +1

Isotropic inhomogeneous dust universes are analysed via observational coordinates based on the past light cones of the observer's galactic worldline. The field equations are reduce…

The Structure of CDM Halos

Julio F. Navarro

High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple ``universal''…
