Gas Dynamics in the Milky Way: Second Pattern Speed and Large-Scale Morphology
Nicolai Bissantz, Peter Englmaier, Ortwin Gerhard
We present new gas flow models for the Milky Way inside the solar circle. To this end we use SPH simulations in gravitational potentials determined from the NIR luminosity distribu…
Distribution of star-forming complexes in dwarf irregular galaxies
B. R. Parodi, B. Binggeli
We study the distribution of bright star-forming complexes in a homogeneous sample of 72 late-type (``irregular'') dwarf galaxies located within the 10 Mpc volume. Star-forming com…
A catalog of warps in spiral and lenticular galaxies in the Southern hemisphere
M. L. Sanchez-Saavedra, E. Battaner, A. Guijarro +2
A catalog of optical warps of galaxies is presented. This can be considered complementary to that reported by Sanchez-Saavedra et al., with 42 galaxies in the northern hemisphere,…
Entanglement in SU(2)-invariant quantum spin systems
John Schliemann
We analyze the entanglement of SU(2)-invariant density matrices of two spins , using the Peres-Horodecki criterion. Such density matrices arise from therma…
Electron spin evolution induced by interaction with nuclei in a quantum dot
Alexander Khaetskii, Daniel Loss, Leonid Glazman
We study the decoherence of a single electron spin in an isolated quantum dot induced by hyperfine interaction with nuclei for times smaller than the nuclear spin relaxation time.…
Isolated Star Formation: A Compact HII Region in the Virgo Cluster
Ortwin Gerhard, Magda Arnaboldi, Kenneth C. Freeman +1
We report on the discovery of an isolated, compact HII region in the Virgo cluster. The object is located in the diffuse outer halo of NGC 4388, or could possibly be in intracluste…
Short-lived p-nuclides in the early solar system and implications on the nucleosynthetic role of X-ray binaries
Nicolas Dauphas, Thomas Rauscher, Bernard Marty +1
The data available for short-lived -nuclides are used in an open nonlinear model of the chemical evolution of the Galaxy in order to discuss the origin of extinct radionuclides,…
Candidates for Intracluster Planetary Nebulae in the Virgo Cluster based on the Suprime-Cam Narrow-Band Imaging in O[III] and Halpha
S. Okamura, N. Yasuda, M. Arnaboldi +17
We have identified 38 candidates of intracluster planetary nebulae (ICPNe) in a field in the core of the Virgo cluster based on the Suprime-Cam imaging through two n…
The Neutrino Signal in Stellar Core Collapse and Postbounce Evolution
M. Liebendoerfer, A. Mezzacappa, O. E. B. Messer +3
General relativistic multi-group and multi-flavor Boltzmann neutrino transport in spherical symmetry adds a new level of detail to the numerical bridge between microscopic nuclear…
Non-ballistic spin field-effect transistor
John Schliemann, J. Carlos Egues, Daniel Loss
We propose a spin field-effect transistor based on spin-orbit (s-o) coupling of both the Rashba and the Dresselhaus types. Differently from earlier proposals, spin transport throug…
The reaction and the magnetic dipole moment of the resonance
M. Kotulla, J. Ahrens, J. R. M. Annand +18
The reaction has been measured with the TAPS calorimeter at the Mainz Microtron accelerator facility MAMI for energies between = 1221--1331 M…
Quark Matter in Neutron Star Mergers
R. Oechslin, G. Poghosyan, K. Uryu
Binary neutron star mergers are expected to be one of the most promising source of gravitational waves (GW) for the network of laser interferometric and bar detectors becoming oper…
Search for Single Top Production at LEP
L3 Collaboration
Single top production in e+e- annihilations is searched for in data collected by the L3 detector at centre-of-mass energies from 189 to 209 GeV, corresponding to a total integrated…
Shot Noise and Proximity Effect in Superconductor--Normal-Metal Heterostructures
W. Belzig, J. Boerlin, C. Bruder +1
Current noise provides useful information on correlations important for transport properties of mesoscopic systems. Of particular interest, both experimentally and theoretically, a…
Geometric construction of spinors in orthogonal modular categories
Anna Beliakova
A geometric construction of Z_2-graded orthogonal modular categories is given. Their 0-graded parts coincide with categories previously obtained by Blanchet and the author from the…
Smearing of charge fluctuations in a grain by spin-flip assisted tunneling
Karyn Le Hur, Pascal Simon
We investigate the charge fluctuations of a grain (large dot) coupled to a lead via a small quantum dot in the Kondo regime. We show that the strong entanglement of charge and spin…
The s-process branching at 185W
K. Sonnabend, P. Mohr, K. Vogt +6
The neutron capture cross section of the unstable nucleus 185W has been derived from experimental photoactivation data of the inverse reaction 186W(gamma,n)185W. The new result of…
Electron capture rates for core collapse supernovae
J. M. Sampaio, K. Langanke, G. Martinez-Pinedo +2
Electron capture rates on neutron-rich nuclei (A>65) were calculated within the Random Phase Approximation with partial number formalism, including allowed and forbidden transition…
Measurement of fast bars in a sample of early-type barred galaxies
J. A. L. Aguerri, V. P. Debattista, E. M. Corsini
We present surface photometry and stellar kinematics of a sample of 5 SB0 galaxies: ESO 139-G009, IC 874, NGC 1308, NGC 1440 and NGC 3412. We measured their bar pattern speed using…
