Internal Kinematics of the Fornax Dwarf Spheroidal Galaxy
We present new radial velocity results for 178 stars in the Fornax dwarf spheroidal galaxy, of which at least 158 are probable Fornax members. We combine with previously published data to obtain a radial velocity sample with 209 stars, of which at least 179 are probable Fornax members. We detect the hint of rotation about an axis near Fornax’s morphological minor axis, though the significance o...
متن کاملInternal Kinematics of the Andromeda Ii Dwarf Spheroidal Galaxy
The High Resolution Echelle Spectrometer on the Keck I telescope has been used to measure nine radial velocities having a median precision of ' 2 km s−1 for seven red giants belonging to the isolated dwarf spheroidal galaxy Andromeda II (And II). We find a weighted mean radial velocity of vr = –188±3 km s−1 and a central velocity dispersion of σ0 = 9.3 −2.6 km s −1. There may be evidence for a ...
متن کاملThe stellar populations of the Fornax dwarf spheroidal galaxy
We present B, V, I CCD photometry of about 40000 stars in four regions of the Fornax dwarf spheroidal galaxy down to V ∼ 23.5, the largest three-color data set obtained for this galaxy until now. The resultant color-magnitude diagrams, based on a wide color baseline, show a variety of features tracing the history of star formation of this dwarf galaxy. One of the most distinctive features in ou...
متن کاملThe Internal Kinematics of Dwarf Spheroidal Galaxies
The status of kinematic observations in Local Group dwarf spheroidal galaxies (dSphs) is reviewed. Various approaches to the dynamical modelling of these data are discussed and some general features of dSph dark matter haloes based on simple mass models are presented.
متن کاملA Wide-Field Survey of the Fornax Dwarf Spheroidal Galaxy
The results of a photometric survey of the Fornax dwarf spheroidal galaxy are presented herein. Accurate photometry in two colours (V and I) was collected over a 10 deg area centred on the Fornax system with the aim of searching for extra-tidal structure. The data were complete to a magnitude of V = 20, or approximately one magnitude brighter than the Fornax red clump stars. Stars were selected...
