An unusual high-ionization nebula in NGC55

R. Tuellmann, M. R. Rosa

We report on the detection of a previously unknown extended low-density nebula of very high temperature and excitation, TR001507.7-391206, located above the midplane of NGC55. The…

A spectral and spatial analysis of eta Carinae's diffuse X-ray emission using CHANDRA

Kerstin Weis, Michael F. Corcoran, Dominik J. Bomans +1

The luminous unstable star (star system) eta Carinae is surrounded by an optically bright bipolar nebula, the Homunculus and a fainter but much larger nebula, the so-called outer e…

Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB 030329

J. Greiner, S. Klose, K. Reinsch +23

We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. We establish the polarization light curve, detect susta…

Formation of current sheets and sigmoidal structure by the kink instability of a magnetic loop

B. Kliem, V. S. Titov, T. Toeroek

We study dynamical consequences of the kink instability of a twisted coronal flux rope, using the force-free coronal loop model by Titov & Démoulin (1999) as the initial condition…

Ideal kink instability of a magnetic loop equilibrium

T. Toeroek, B. Kliem, V. S. Titov

The force-free coronal loop model by Titov & Démoulin (1999} is found to be unstable with respect to the ideal kink mode, which suggests this instability as a mechanism for the ini…

Hot Dust in Radio-Loud Active Galactic Nuclei

Wolfram Freudling, Ralf Siebenmorgen

We have measured mid-infrared (MIR) fluxes of 3C sources on images taken with ISOCAM onboard the Infrared Space Observatory (ISO). The photometric data were combined with existing…
