Star Formation History of the SMC: six HST/ACS
E. Sabbi, J. S. Gallagher, M. Tosi +9
We observed six fields of the Small Magellanic Cloud (SMC) with the Advanced Camera for Survey on board the Hubble Space Telescope in the F555W and F814W filters. These fields samp…
Testing Fundamental Physics with Distant Star Clusters: Analysis of Observational Data on Palomar 14
K. Jordi, E. K. Grebel, M. Hilker +6
We use the distant outer halo globular cluster Palomar 14 as a test case for classical vs. modified Newtonian dynamics (MOND). Previous theoretical calculations have shown that the…
Scl-dE1 GC1: An Extended Globular Cluster in a Low-Luminosity Dwarf Elliptical Galaxy
G. S. Da Costa, E. K. Grebel, H. Jerjen +2
We report the discovery from Hubble Space Telescope ACS images of an extended globular cluster, denoted by Scl-dE1 GC1, in the Sculptor Group dwarf Elliptical galaxy Scl-dE1 (Sc22)…
Galactic Dynamics and Local Dark Matter
Steven R. Majewski, James Bullock, Andreas Burkert +13
The concordance Lambda Cold Dark Matter (Lambda-CDM) model for the formation of structure in the Universe, while remarkably successful at describing observations of structure on la…
Discovery of the first symbiotic star in NGC6822
A. Kniazev, P. Vaisanen, P. A. Whitelock +10
We report the discovery of the first symbiotic star (V=21.6, K_S=15.8 mag) in the Local Group dwarf irregular galaxy NGC6822. This star was identified during a spectral survey of H…
