ESO-VLT optical spectroscopy of BL Lac objects: I. new redshifts
B. Sbarufatti, A. Treves, R. Falomo +3
We report redshift measurements for 12 BL Lacertae objects from a program aimed at obtaining high signal to noise (up to ~ 500) optical spectroscopy of a mixed sample of objects. T…

Quantitative interpretation of the rotation curves of spiral galaxies at redshifts z~0.7 and z~1
Burkhard Fuchs, Asmus Boehm, Claus Moellenhoff +1
We present decompositions of the rotation curves of three spiral galaxies at redshifts z~0.7 and 1 into contributions by their bulges, disks, and dark halos, respectively. In order…

Internal kinematics of spiral galaxies in distant clusters. Part II. Observations and data analysis
K. Jaeger, B. L. Ziegler, A. Boehm +5
We have conducted an observing campaign with FORS at the ESO-VLT to explore the kinematical properties of spiral galaxies in distant galaxy clusters. Our main goal is to analyse tr…
