Propagation of Muons and Taus at High Energies
S. Iyer Dutta, M. H. Reno, I. Sarcevic +1
The photonuclear contribution to charged lepton energy loss has been re-evaluated taking into account HERA results on real and virtual photon interactions with nucleons. With large…
The Origin of the Magnetic Fields of the Universe: The Plasma Astrophysics of the Free Energy of the Universe
S. A. Colgate, H. Li, V. Pariev
(abridged) The interpretation of Faraday rotation measure maps of AGNs within galaxy clusters has revealed regions, kpc, that are populated with large, G…
The Cyclotron Fundamental Exposed in the High-Field Magnetic Variable V884 Her
G. D. Schmidt, L. Ferrario, D. T. Wickramasinghe +1
High-quality phase-resolved optical spectropolarimetry is presented for the magnetic cataclysmic variable V884 Her. The overall circular polarization during active accretion states…
On the eta-eta' complex in the SD-BS approach
Dubravko Klabucar, Dalibor Kekez, Michael D. Scadron
The bound-state Schwinger-Dyson and Bethe-Salpeter (SD-BS) approach is chirally well-behaved and provides a reliable treatment of the eta-eta' complex although a ladder approximati…
Measurement of one-particle correlations and momentum distributions for trapped 1D gases
M. D. Girardeau, E. M. Wright
van Hove's theory of scattering of probe particles by a macroscopic target is generalized so as to relate the differential cross section for atomic ejection via stimulated Raman tr…
Final Results from the Hubble Space Telescope Key Project to Measure the Hubble Constant
W. L. Freedman, B. F. Madore, B. K. Gibson +12
We present here the final results of the Hubble Space Telescope Key Project to measure the Hubble constant. We summarize our method, the results and the uncertainties, tabulate our…
The Power Spectrum Dependence of Dark Matter Halo Concentrations
V. R. Eke, J. F. Navarro, M. Steinmetz
High-resolution N-body simulations are used to examine the power spectrum dependence of the concentration of galaxy-sized dark matter halos. It is found that dark halo concentratio…
A Large-Scale Jet and FR I Radio Source in a Spiral Galaxy: The Host Properties and External Environment
Michael J. Ledlow, Frazer N. Owen, Min S. Yun +1
We have identified a large (~200 kpc), powerful double radio source whose host galaxy is clearly a disk and most likely a spiral. This FR I radio galaxy is located very near the ce…
Mapping the Galactic Halo III. Simulated Observations of Tidal Streams
Paul Harding, Heather L. Morrison, Edward W. Olszewski +5
We have simulated the evolution of tidal debris in the Galactic halo in order to guide our ongoing survey to determine the fraction of halo mass accreted via satellite infall. Cont…
A Measurement of the Branching Ratio and Asymmetry of the Decay Cascade^0-->Sigma^0/gamma
A. Alavi-Harti
We have studied the rare weak radiative hyperon decay Cascade0-->Sigma0/gamma in the KTeV experiment at Fermilab. We have identified 4045 signal events over a background of 804 eve…
The Optical Spectroscopic Evolution of V1974 Cygni (Nova Cygni 1992)
A. Moro-Martin, P. M. Garnavich, A. Noriega-Crespo
Optical observations of nova V1974 Cygni (Cygni 1992), spanning a 4 year period, have been used to study its spectroscopic evolution. The data cover a wavelength range from $\sim 3…
Helicity in Hydro and MHD Reconnection
Axel Brandenburg, Robert M. Kerr
Helicity, a measure of the linkage of flux lines, has subtle and largely unknown effects upon dynamics. Both magnetic and hydrodynamic helicity are conserved for ideal systems and…
A Multivariate Analysis of Galaxies in the Hubble Deep Field North
Michael R. Corbin, Andrea Urban, Elizabeth Stobie +2
We use the ultraviolet and optical WFPC2 and near-infrared NICMOS images of the Hubble Deep Field North to measure and statistically compare an array of parameters for over 250 of…
Weak lensing study of low mass galaxy groups: implications for Omega_m
H. Hoekstra, M. Franx, K. Kuijken +8
We report on the first measurement of the average mass and mass-to-light ratio of galaxy groups by analysing the weak lensing signal induced by these systems. The groups, which hav…
Ultraviolet and Optical Observations of OB Associations and Field Stars in the Southwest Region of the Large Magellanic Cloud
Joel Wm. Parker, Dennis Zaritsky, Theodore P. Stecher +2
Using photometry from the Ultraviolet Imaging Telescope (UIT) and photometry and spectroscopy from three ground-based optical datasets we have analyzed the stellar content of OB as…
A Search for the Damped Ly-alpha Absorber at z=1.86 toward QSO 1244+3443 with NICMOS
Varsha P. Kulkarni, John M. Hill, Glenn Schneider +5
We have carried out a high-resolution imaging search for the galaxy associated with the damped Lyman-alpha (DLA) absorber at z=1.859 toward the z_{em}=2.48 quasar QSO 1244+3443, us…
Radiative VPgamma transitions and eta-eta' mixing
A. Bramon, R. Escribano, M. D. Scadron
A value for the - mixing angle is extracted from the data on transitions using simple quark-model ideas. The set of data covers {\it all} possible radiative tran…
The non-stellar infrared continuum of Seyfert galaxies
A. Alonso-Herrero, A. C. Quillen, C. Simpson +2
JHKL'M (1-5 micron) imaging of a sample of Seyfert (Sy) 2 galaxies is presented. We confirm that the 1-2.2 micron nuclear continuum of some Sy 2s is dominated by stellar emission,…
