The Outer Cluster System of NGC 1399: Preliminary Results
Y. Schuberth, T. Richtler, B. Dirsch +2
We present preliminary results of our dynamical study of the outer globular cluster system of NGC 1399, the central galaxy in the Fornax Cluster. About 160 new radial velocities fo…
The Outer Halo Cluster System of NGC 1399
B. Dirsch, D. Geisler, T. Richtler +1
We investigate the outer halo globular cluster population of NGC 1399. This study uses wide-field imaging of this cluster system, which covers the largest area studied with CCD pho…
Spectroscopy of Globular Clusters in NGC 1399 - A Progress Report
T. Richtler, B. Dirsch, D. Geisler +9
We performed spectroscopy of globular clusters associated with NGC 1399 and measured radial velocities of more than 400 clusters, the largest sample ever obtained for dynamical stu…
Optical observations of the black hole candidate XTE J1550-564 during the Sep/Oct 1998 outburst
C. Sanchez-Fernandez, A. J. Castro-Tirado, H. W. Duerbeck +11
We report here optical observations during the September/October 1998 outburst of the black hole candidate XTE J1550-564. CCD photometry was obtained for the optical counterpart wi…
