A Search for Cold Dust around Neutron Stars
O. Loehmer, A. Wolszczan, R. Wielebinski
We present observations of nine radio pulsars using the Heinrich-Hertz-Telescope at λ0.87mm and the IRAM 30-m telescope at λ1.2mm in search for a cold dust around these sources. Fi…
Cold dust in a selected sample of nearby galaxies. I. The interacting galaxy NGC4631
M. Dumke, M. Krause, R. Wielebinski
We have observed the continuum emission of the interacting galaxy NGC4631 at 0.87 and 1.23mm using the Heinrich-Hertz-Telescope on Mt. Graham and the IRAM 30-m telescope on Pico Ve…
Gas physics and dynamics in the central 50 pc of the Galaxy
B. Vollmer, W. J. Duschl, R. Zylka
We present models the gas physics and dynamics of the inner 50 pc of the Galaxy. In a first step the gas properties of an isolated clumpy circumnuclear disk were analytically inves…
One-sided jet at milliarcsecond scales in LSI+61303
M. Massi, M. Ribo, J. M. Paredes +2
We present Very Long Baseline Interferometry (VLBI) observations of the high mass X-ray binary LSI+61303, carried out with the European VLBI Network (EVN). Over the 11 hour observi…
Circumstellar disc of beta Pictoris: constraints on grain properties from polarization
N. V. Voshchinnikov, E. Kruegel
We model the positional dependence of the optical polarization (BVRI-bands) in the circumstellar disc of beta Pictoris as observed by Gledhill et al. (1991) and Wolstencroft et al.…
