The phase-space density distribution of dark matter halos
Liliya L. R. Williams, Crystal Austin, Eric Barnes +2
High resolution N-body simulations have all but converged on a common empirical form for the shape of the density profiles of halos, but the full understanding of the underlying ph…
Disk Galaxy Rotation Curves in Triaxial CDM Halos
E. Hayashi, J. F. Navarro, A. Jenkins +7
We use N-body hydrodynamical simulations to study the structure of disks in triaxial potentials resembling CDM halos. Our analysis focuses on the accuracy of the dark mass distribu…
The double main sequence of Omega Centauri
L. R. Bedin, G. Piotto, J. Anderson +4
Recent, high precision photometry of Omega Centauri, the biggest Galactic globular cluster, has been obtained with Hubble Space Telescope. The color magnitude diagram reveals an un…
Accurate Internal Proper Motions of Globular Clusters
L. R. Bedin, G. Piotto, J. Anderson +1
We have undertaken a long term program to measure high precision proper motions of nearby Galactic globular cluster (GC) stars using multi-epoch observations with the WFPC2 and the…
Kinematics of the HH 111 jet from STIS spectra
A. C. Raga, A. Noriega-Crespo, B. Reipurth +4
We present a long-slit spectrum of the Herbig-Haro object HH 111, obtained with SITS on the Hubble Space Telescope. This spectrum has a spectral resolution of approx. 50 km/s, so i…
Detailed abundance analysis of 8 super-metal-rich star candidates
Sofia Feltzing, Guillermo Gonzalez
We provide detailed abundance analyses of 8 candidate super-metal-rich stars. Five of them are confirmed to have [Fe/H] > 0.2 dex, the generally-accepted limit for super-metal-rich…
