SUMMARY:S4G: The Spitzer Survey of Stellar Structure in Galaxies
DESCRIPTION:S4G: The Spitzer Survey of Stellar Structure in Galaxies\nDr. J
 ohan Knapen\n\nGalaxies are the basic building blocks of the Universe, and
  understanding their formation and evolution is crucial to many areas of c
 urrent astrophysical research. Nearby galaxies, being the 'fossil record' 
 of the evolution of galaxies, provide a wealth of detail to test extensive
 ly the current models of galaxy formation and evolution. A galaxy's struct
 ure is linked to both its mass and evolutionary history. Probing galactic 
 structure requires understanding the distribution of stars among galaxies 
 of all types and luminosities across the full range of environments. We ar
 e performing a complete volume-limited (d < 40 Mpc) survey of over 2200 ne
 arby spiral, elliptical and dwarf galaxies at 3.6 and 4.5 &mu; in the Spit
 zer Warm Mission to address fundamental questions of galactic structure th
 at are united by the common need for deep, uniform, unbiased maps of the s
 tellar mass in galaxies. I will introduce the survey, give examples of ima
 ges and of the science that can be done, and explain how other researchers
  at the IAC can become involved in analysing these exciting data.\n\n
