    Active galactic nuclei synapses: X-ray versus optical classifications using artificial neural networks
    The active galactic nuclei is conformed by a number of classes. Optically they are defined using diagnostics based on optical emission lines. At X-rays they are...

    AGN activity in Local Luminous Infrared Galaxies
    Luminous Infrared Galaxies (LIR=10^11-10^12Lsun) have star formation rates in the range of ~20-200Msun/yr. In the local Universe ~50% LIRGs show AGN or AGN/SB...

    AGN winds, feedback and the baryon cycle in the galaxy ecosystem
    Why did galaxies stop forming stars? Why do black holes in galactic nuclei have masses proportional to bulge masses? What are the physical mechanisms leading...

    An optical/NIR survey of globular clusters in early-type galaxies
    The colour distribution of globular cluster (GC) systems in the majority of galaxies is bi/multimodal in optical colours. It is widely accepted that multiple...

    Are luminous quasars triggered in galaxy mergers?
    The mechanism by which AGN activity is triggered has long been debated. One, often suggested, method of doing so is major, gas-rich mergers and galaxy...
