An HST Census of Nuclear Star Clusters in Late-Type Spiral Galaxies: I. Observations and Image Analysis
Torsten Boeker, Seppo Laine, Roeland P. van der Marel +4
We present new HST I-band images of a sample of 77 nearby, late-type spiral galaxies with low inclination. The main purpose of this catalog is to study the frequency and properties…
Eta-N Final State Interaction in incoherent Photoproduction of Eta-mesons from the Deuteron near Threshold
A. Sibirtsev, S. Schneider, Ch. Elster +3
An analysis of incoherent photoproduction of mesons off the deuteron for photon energies from threshold to 800 MeV is presented. The dominant contribution, the N-N amplit…
The Metallicity of the Redshift 4.16 Quasar BR2248-1242
Craig Warner, Fred Hamann, Joseph C. Shields +3
We estimate the metallicity in the broad emission-line region of the redshift z=4.16 quasar, BR2248-1242, by comparing line ratios involving nitrogen to theoretical predictions. BR…
First Measurement of the Double Spin Asymmetry in in the Resonance Region
CLAS Collaboration, R. De Vita
The double spin asymmetry in the reaction has been measured for the first time in the resonance region for four-momentum transfer GeV$^2…
Excitons in quantum-ring structures in a magnetic field: Optical properties and persistent currents
A. O. Govorov, A. V. Kalameitsev, R. Warburton +2
We study theoretically the magnetic field effect on a neutral, but polarizable exciton confined in quantum-ring structures. For excitons with a nonzero dipole moment, a novel magne…
Magnetoexcitons in quantum-ring structures: a novel magnetic interference effect
S. E. Ulloa, A. O. Govorov, A. V. Kalameitsev +2
A novel magnetic interference effect is proposed for a neutral, but polarizable exciton in a quantum ring with a finite width. The magnetic interference effect originates from the…
