DESCRIPTION:Spectral synthesis of galaxies is the science/art of digging a
 s much\ninformation as possible from galaxy spectra. In the last decade\,\
 nevolutionary synthesis models with decent spectral resolution in the\nopt
 ical have promoted huge advances in this area\, which\, combined with\nthe
  avalanche of data has lead to substantial progress in our\nunderstanding 
 of galaxies. The STARLIGHT code is one such tool in this\nbusiness. It per
 forms Angstrom-by-Angstrom fits of galaxy spectra\ncombining models of sim
 ple stellar populations of various ages and\nmetallicities. It has been em
 ployed to address a variety of issues\, from\nproblems where one seeks inf
 ormation on stellar population mixtures\n(a.k.a. Star Formation Histories)
 \, to others where one is more\ninterested in getting rid of stellar light
  in order to measure emission\nlines\, to study stellar kinematics\, and e
 ven to test the ingredients\n(SSP models) themselves.\n\nThis talk will (1
 ) review the basics of spectral synthesis and\nillustrate its power as a t
 ool to study galaxy evolution in 1D (ie\,\nSDSS-like integrated spectra)\,
  and (2) present the 1st results of the\napplication of STARLIGHT to the 1
 st 100 galaxies observed in the CALIFA\nsurvey. CALIFA is collecting data 
 cubes (integral field spectroscopy)\nfor 600 galaxies (~ 1000 spectra per 
 target) spread over the color\nmagnitude diagram. Dissecting galaxy spectr
 a as a function of position\nis showing us how the different morphological
  components of galaxies\nbuild their mass and metals over time\, and promi
