Resolved Stellar Populations in Nearby Galaxy Halos
2009The results of the three different studies of resolved stellar populations in galaxies across the Hubble sequence based on HST ACS and WFPC2 data are summarized in this contribution. (1) The ACS observations of the stellar halo of the gE galaxy NGC 5128 revealed the core helium-burning stars located in the red clump.

The formation of stellar halos in late-type galaxies
2007Near–field observations may provide tight constraints - i.e. 'boundary conditions' - on any model of structure formation in the Universe. Detailed observational data have long been available for the Milky Way (e.g., Freeman and Bland-Hawthorn 2002) and have provided tight constraints on several Galaxy formation models (e.g.: Abadi et al.

Stars and stellar haloes at the EDGE of galaxy formation
Dwarf galaxies in our Universe are sensitive to small-scale evolutionary processes, thus of-fering unparalleled opportunities for testing galaxy formation theories and understandingdark matter behaviour. Their proximity to the Milky Way allows for detailed structuraland compositional analysis, which is crucial for refining cosmological models.The ...openaire +2 more sources
