The completeness of stellar spectral libraries in all stellar evolutionary phases, parameter space (effective temperature, surface gravity, global metallicity) and chemical abundances, is required to build more sophisticated stellar population synthesis models to decode the enclosed information of galaxies of varying types. On the hand, due to

Context: Bar formation and merger events can contribute to the rearrangement of stars within the Galaxy in addition to triggering star formation (SF) epochs. Super-metal-rich (SMR) stars found in the solar neighbourhood (SNd) can be used as tracers of such events as they are expected to originate only in the inner Galaxy and to have definitely

The deepest ground-based optical surveys (in terms of surface brightness mu~31 mag/arcsec^2) show that we are close to the dreaded source confusion limit. The typical distance between sources in these images is a few arcseconds, on the order of the natural seeing in these images. When this source confusion limit is reached, low surface brightness
