Lithium is a key element which plays an important role in astronomy as well as everyday human life. Nevertheless it is probably the only element whose astronomical origin is still a mystery. A fraction of about 30% of what is measured today was made in the first 3 minutes of the Universe and about 10% is made by spallation reactions of cosmic rays

Dwarf galaxies are powerful tools of near-field cosmology and galactic archaeology: their numbers, distribution, and star formation can be linked to both the tenets of LCDM (the missing satellite "problem," their (an)isotropic distribution, their dark matter content) and to the build up of their hosts and their environment (accretion, quenching)

I present a detailed analysis of the scaling relations of ETGs and suggest a way to predict the evolution of the distributions of galaxies in these planes. This new approach is able to account of several features observed in the FP projections and of the tilt of the Fundamental Plane.

MAAT is a mirror-slicer integral field unit that will be installed in OSIRIS in 2024, breathing new life into the GTC's work horse instrument. As well as the opportunity to perform spatially-resolved spectroscopy over a field of 10"x7", MAAT will also offer increased signal-to-noise and resolution for point sources with respect to the standard long
