Age-dating a star-burst with GEMINI/CIRPASS observations of the core of M83
We present preliminary results from a set of near-IR integral field spectroscopic observations of the central, star-burst, regions of the barred spiral galaxy...
Ages and chemical properties of stellar populations from integrated spectra and spectral indexes
The various methods for studying in detail relevant stellar population parameters throught the integrated light are reviewed. The emphasis is given to the...
The SDSS-III Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a high resolution (R ~23,000) near-IR (H-band) spectroscopic survey of 100,000...
AGN Activity and Circumnuclear Star Formation in Nearby Galaxies
We have selected a sample of nearby galaxies where an AGN (Seyfert or LINER) coexists with circumnuclear star formation. We use the highest spatial resolution...
AGN feedback and chemical enrichment on galaxy scales
Giant (>100 kpc) nebulae associated with active galaxies provide rich information about the circumgalactic medium (CGM) around galaxies, its link with the...
AGN feedback and the origin and fate of the hot gas in early-type galaxies
We present the results of two-dimensional, grid-type hydrodynamical simulations, with parsec-scale central resolution, for the evolution of the hot gas in...
