"Low- and high-resolution spectroscopic analysis of nuclear and bright globular clusters in nearby dwarf galaxies"

Bright star clusters in the nuclear regions of dwarf galaxies have been envisioned to be the progenitors, upon (proto)dwarf 
galaxy accretion, of a subpopulation of peculiar Galactic globular clusters (GCs), e.g. wCen, NGC 2419 and M54. The latter is 
still associated with the nucleus of the dissolving into the Galactic potential Sagittarius dSph. Common progenitor 
environment of such clusters will be imprinted into the indicators of the pace of stellar, chemical and dynamical evolutionary 
history of those systems, such as their element abundance, internal dynamics and structure. To probe for their common 
origin we will present results from a low-resolution VLT FORS2/MOS and UVES high-resolution spectroscopic observations of 
nuclear clusters in Local Volume dwarf galaxies. Low-resolution line absorption analysis in the spectral range ~ 3500 - 6000 
A, allows us to confirm GCs membership in the studied dwarfs and derive their integrated luminosity-weighted metallicities 
and ages. High-resolution UVES absorption line width analysis enabled us to derive internal cluster velocity dispersions and 
calculate their dynamical mass (M_dyn). These values are directly compared to those of the peculiar Galactic GCs.
