A multiwavelength study of the galaxy content and environmental effects in the dense group of galaxies around IC 65
J. Vennik, U. Hopp
We have carried out surface photometry of four bright known members and a number of new possible LSB companions of the IC 65 (LGG 16) group of galaxies. The purpose of the present…
Spectra of High Redshift Galaxies using a Cluster as a Gravitational Telescope
D. Mehlert, S. Seitz, R. P. Saglia +7
Using the Focal Reducer Spectrograph (FORS) at the Very Large Telescope (VLT) during the FORS commissioning time in December 1998 we took long slit spectra of the gravitational arc…
A transition from linear to circular polarization in pulsar radio emission
Alexis von Hoensbroech, Harald Lesch
At present three pulsars are known which clearly show a strongly increasing degree of circular polarization with frequency. As this is accompanied by a smooth decrease of linear po…
Dynamical Mass Determination for Elliptical Galaxies
Ortwin Gerhard, Gunther Jeske, R. P. Saglia +1
The mass and anisotropy of an elliptical galaxy can be simultaneously determined from velocity dispersion and line profile shape measurements. We describe the principles, technique…
