Structure and Kinematics of the Nearby Dwarf Galaxy UGCA 105
Philip Schmidt, Gyula Jozsa, Gianfranco Gentile +5
Owing to their shallow stellar potential, dwarf galaxies possess thick gas disks, which makes them good candidates for studies of the galactic vertical kinematical structure. We pr…
Dynamics of the NGC 4636 globular cluster system II. Improved constraints from a large sample of globular cluster velocities
Ylva Schuberth, Tom Richtler, Michael Hilker +3
We present new radial velocities for 289 globular clusters around NGC 4636, the southernmost giant elliptical galaxy of the Virgo cluster. The data were obtained with FORS2/MXU at…
Kinematic properties of the field elliptical NGC 7507
R. Salinas, T. Richtler, L. P. Bassino +2
The dark matter (DM) halos of field elliptical galaxies have not been well studied and their properties appear controversial. While some galaxies appear to be nearly devoid of DM,…
A large population of ultra-compact dwarf galaxies in the Hydra I cluster
I. Misgeld, S. Mieske, M. Hilker +3
We performed a large spectroscopic survey of compact, unresolved objects in the core of the Hydra I galaxy cluster (Abell 1060), with the aim of identifying ultra-compact dwarf gal…
Remarks on the properties of elliptical galaxies in modified Newtonian dynamics
Tom Richtler, Benoit Famaey, Gianfranco Gentile +1
Two incorrect arguments against MOND in elliptical galaxies could be that the equivalent circular velocity curves tend to become flat at much larger accelerations than in spiral ga…
The dark halo of the Hydra I galaxy cluster: core, cusp, cosmological? Dynamics of NGC 3311 and its globular cluster system
T. Richtler, R. Salinas, I. Misgeld +5
NGC 3311 is the central cD galaxy of the Hydra I cluster. We use globular clusters around NGC 3311, combined with kinematical data of the galaxy itself, to investigate the dark mat…
