Extended Ly-alpha emission from a damped Ly-alpha absorber at z = 1.93, and the relation between DLAs and Lyman-break galaxies

J. U. Fynbo, P. Moller, S. J. Warren

The number of damped Ly-alpha absorbers (DLAs) currently known is about 100, but our knowledge of their sizes and morphologies is still very sparse as very few have been detected i…

Canonical phase space approach to the noisy Burgers equation

Hans C. Fogedby

Presenting a general phase approach to stochastic processes we analyze in particular the Fokker-Planck equation for the noisy Burgers equation and discuss the time dependent and st…

Computer simulations of defects in perovskite KNbO3 crystals

R. I. Eglitis, E. A. Kotomin, A. V. Postnikov +3

An ab initio LMTO approach and semi-empirical quantum chemical INDO method have been used for supercell calculations of basic point defects - F-type centers and hole polarons bound…

A search for solar-like oscillations and granulation in alpha Cen A

H. Kjeldsen, T. R. Bedding, S. Frandsen +1

We report the most sensitive search yet made for solar-like oscillations. We observed the star alpha Cen A in Balmer-line equivalent widths over six nights with both the 3.9m Anglo…

Competition of isoscalar and isovector proton-neutron pairing in nuclei

G. Martinez-Pinedo, K. Langanke, P. Vogel

We use shell model techniques in the complete pf shell to study pair correlations in nuclei. Particular attention is paid to the competition of isoscalar and isovector proton-neutr…

Breakup Reactions of 11Li within a Three-Body Model

E. Garrido, D. V. Fedorov, A. S. Jensen

We use a three-body model to investigate breakup reactions of 11Li (n+n+9Li) on a light target. The interaction parameters are constrained by known properties of the two-body subsy…
