Disc formulas for the weighted Siciak-Zahariuta extremal function
Benedikt Steinar Magnusson, Ragnar Sigurdsson
We prove a disc formula for the weighted Siciak-Zahariuta extremal function for an upper semicontinuous function on an open connected subset in $\C^n$. This funct…
Extensive multiband study of the X-ray rich GRB 050408. A likely off-axis event with an intense energy injection
A de Ugarte Postigo, T. A. Fatkhullin, G. Johannesson +40
Aims. Understand the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst. Methods. We present a multiband optical light curve, covering the…
Coherent magnetotransport spectroscopy in an edge-blocked double quantum wire with window and resonator coupling
Chi-Shung Tang, Vidar Gudmundsson
We propose an electronic double quantum wire system that contains a pair of edge blocking potential and a coupling element in the middle barrier between two ballistic quantum wires…
Magnetotransport in a double quantum wire: Modeling using a scattering formalism built on the Lippmann-Schwinger equation
Vidar Gudmundsson, Chi-Shung Tang
We model electronic transport through a double quantum wire in an external homogeneous perpendicular magnetic field using a scattering formalism built on the Lippmann-Schwinger equ…
The spectral dimension of generic trees
Bergfinnur Durhuus, Thordur Jonsson, John F. Wheater
We define generic ensembles of infinite trees. These are limits as of ensembles of finite trees of fixed size , defined in terms of a set of branching weights. Amon…
GRB 060121: Implications of a Short/Intermediate Duration Gamma-Ray Burst at High Redshift
A. de Ugarte Postigo, A. J. Castro-Tirado, S. Guziy +23
Since the discovery of the first short-hard gamma-ray burst afterglows in 2005, the handful of observed events have been found to be embedded in nearby (z < 1), bright underlying g…
