VLT-UVES observations of the Balmer line variations of eta Carinae during the 2003 spectroscopic event

Kerstin Weis, Otmar Stahl, Dominik J. Bomans +3

We present high spectral resolution echelle observations of the Balmer line variations during the 2003.5 ``spectroscopic event'' of eta Carinae. Spectra have been recorded of both…

Generation of Gravitational Radiation in Dusty Plasmas and Supernovae

G. Brodin, M. Marklund, P. K. Shukla

We present a novel nonlinear mechanism for exciting a gravitational radiation pulse (or a gravitational wave) by dust magnetohydrodynamic (DMHD) waves in dusty astrophysical plasma…

GaBoDS: The Garching-Bonn Deep Survey - III. Lyman-Break Galaxies in the Chandra Deep Field South

H. Hildebrandt, D. J. Bomans, T. Erben +10

We present first results of our search for high-redshift galaxies in deep CCD mosaic images. As a pilot study for a larger survey, very deep images of the Chandra Deep Field South…

H.E.S.S. Observations of PKS 2155-304

The H. E. S. S. Collaboration, :, F. Aharonian

The high-frequency peaked BL Lac PKS 2155-304 at redshift z=0.117 has been detected with high significance (~45 sigma) at energies greater than 160 GeV, using the H.E.S.S. stereosc…

High-energy particle acceleration in the shell of a supernova remnant

H. E. S. S. Collaboration, :, F. Aharonian

A significant fraction of the energy density of the interstellar medium is in the form of high-energy charged particles (cosmic rays). The origin of these particles remains uncerta…

SN2002kg -- the brightening of LBV V37 in NGC 2403

Kerstin Weis, Dominik J. Bomans

SN2002kg is a type IIn supernova, detected in October 2002 in the nearby spiral galaxy NGC 2403. We show that the position of SN2002kg agrees within the errors with the position of…
