A new definition of the intermediate group of gamma-ray bursts
I. Horvath, L. G. Balazs, Z. Bagoly +2
Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. This classification is somewhat imprecise, since the subgroup o…
One-Dimensional Theory of the Quantum Hall System
Emil J. Bergholtz, Anders Karlhede
We consider the lowest Landau level on a torus as a function of its circumference . When , the ground state at general rational filling fraction is a crystal with a…
The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation
J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13
We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…
On the nature of nearby GRB/SN host galaxies
J. Sollerman, G. Ostlin, J. P. U. Fynbo +3
We present and discuss optical diagnostics of the low redshift (z<0.2) galaxies that are known to have hosted supernovae associated with gamma-ray bursts (GRBs). The three galaxies…
Evolution of the 0.01 - 25 Hz power spectral components in Cygnus X-1
M. Axelsson, L. Borgonovo, S. Larsson
Analyzing the archival data from the Rossi X-ray Timing Explorer (RXTE), we study the power density spectra (PDS) of Cygnus X-1 from 1996 to 2003 in the frequency range of 0.01 - 2…
Topological order and the deconfinement transition in the (2+1) dimensional compact Abelian Higgs model
Anders Vestergren, Jack Lidmar
We study an Abelian compact gauge theory minimally coupled to bosonic matter with charge q, which may undergo a confinement--deconfinement transition in (2+1)D. The transition is a…
