Near-threshold -meson production in proton-proton collisions: With or without resonance excitations ?
K. Tsushima, K. Nakayama
We present results for the reaction studied by considering two different scenarios: with and without the inclusion of nucleon resonance excitations. The recently me…
Helium and Hydrogen Line Ratios and The Stellar Content of Compact HII Regions
S. L. Lumsden, P. J. Puxley, M. G. Hoare +2
We present observations and models of the behaviour of the HI and HeI lines between 1.6 and 2.2um in a small sample of compact HII regions. As in our previous papers on planetary n…
XMM-Newton spectral analysis of the Pulsar Wind Nebula within the composite SNR G0.9+0.1
D. Porquet, A. Decourchelle, R. S. Warwick
We present a study of the composite supernova remnant G0.9+0.1 based on observations by XMM-Newton. The EPIC spectrum shows diffuse X-ray emission from the region corresponding to…
The detection of diffuse emission in HCG 16 with XMM-Newton
E. Belsole, L. Sauvageot, T. J. Ponman +1
We report results obtained from analysis of the XMM-Newton observation of the compact group of galaxies HCG 16. It is a peculiar system composed of 7 spirals, 6 of which are active…
Precision calculation for e+ e- -> 2f: the KK MC project
B. F. L. Ward, S. Jadach, Z. Was
We present the current status of the coherent exclusive (CEEX) realization of the YFS theory for the processes in e+ e- -> 2f via the KK MC. We give a brief summary of the CEEX the…
Ferromagnetic superconductivity driven by changing Fermi surface topology
K. G. Sandeman, G. G. Lonzarich, A. J. Schofield
We introduce a simple but powerful zero temperature Stoner model to explain the unusual phase diagram of the ferromagnetic superconductor, UGe2. Triplet superconductivity is driven…
A Model for Neutrino Masses and Dark Matter
Lawrence M. Krauss, Salah Nasri, Mark Trodden
We propose a model for neutrino masses that simultaneously results in a new dark matter candidate, the right-handed neutrino. We derive the dark matter abundance in this model, sho…
X-ray lighthouses of the high-redshift Universe. Probing the most luminous z>4 Palomar Digital Sky Survey Quasars with Chandra
C. Vignali, W. N. Brandt, D. P. Schneider +2
We present the results from exploratory Chandra observations of nine high-z (z=4.1-4.5) optically selected quasars. These quasars, taken from the DPOSS, are among the optically mos…
Molecular gas freeze-out in the pre-stellar core L1689B
M. P. Redman, J. M. C. Rawlings, D. J. Nutter +2
C17O (J=2-1) observations have been carried out towards the pre-stellar core L1689B. By comparing the relative strengths of the hyperfine components of this line, the emission is s…
Sensitivity of the Auger Observatory to ultra high energy photon composition through inclined showers
M. Ave, J. A. Hinton, R. A. Vazquez +2
We report a calculation of the expected rate of inclined air showers induced by ultra high energy cosmic rays to be obtained by the Auger Southern Observatory assuming different ma…
An alternative interpretation for the Holm "alpha model"
David C. Montgomery, Annick Pouquet
By re-interpreting a recent successful closure procedure in terms of local spatial averaging and the neglect of fluctuations about that average, it is shown how the results of that…
First XMM-Newton results on the Pulsar Wind Nebula in the composite supernova remnant G0.9+0.1
D. Porquet, A. Decourchelle, R. S. Warwick
We report the results of the XMM-Newton observation of the Pulsar Wind Nebula (PWN) in the composite supernova remnant G0.9+0.1 located in the Galactic Center region. Thanks to the…
Subluminous Stars among the FAUST UV sources toward OPHIUCHUS
L. Formiggini, N. Brosch, E. Almoznino +2
We present results of an analysis of a UV image in the direction of Ophiuchus, obtained with the FAUST instrument. The image contains 228 UV sources. Most of these were identified…
Quantum Corrections to Newton's Law
B. F. L. Ward
We present a new approach to quantum gravity starting from Feynman's formulation for the simplest example, that of a scalar field as the representative matter. We show that we exte…
Formation of Turbulent Cones in Accretion Disk Outflows and Application to Broad Line Regions of Active Galactic Nuclei
A. Y. Poludnenko, E. G. Blackman, A. Frank
We consider the stability of an accretion disk wind to cloud formation when subject to a central radiation force. For a vertical launch velocity profile that is Keplerian or flatte…
Chemical short range order obtained from the atomic pair distribution function
Th. Proffen, V. Petkov, S. J. L. Billinge +1
Many crystalline materials show chemical short range order and relaxation of neighboring atoms. Local structural information can be obtained by analyzing the atomic pair distributi…
