SUMMARY:A large spectroscopic survey facility at GTC for the next decade
DESCRIPTION:A large spectroscopic survey facility at GTC for the next decad
 e\nDr. Francisco Prada\n\nIn the next decade astronomers will attempt to c
 onstrain the nature of dark matter, dark energy and the (perhaps inflation
 ary) processes which generated structure as well as understanding the astr
 ophysics of galaxy evolution and the formation and evolution of our Milky 
 Way and Local Group. Large-scale spectroscopic surveys on large telescopes
  will be critical to achieving reliable results in all these areas. The de
 sideratum is a survey which obtains the spectra of a few times 105 galaxie
 s from the visible into the near IR at each of a sufficient number of reds
 hift slices that one can follow the evolution of all interesting populatio
 ns. Large samples of different stellar populations in different Local Grou
 p environments will also be targeted. I will summarize the outline of a mu
 lti-object 0.4-1.7 μ spectrograph for GTC and discuss the status of min
 iSIDE. MiniSIDE has been conceived as a pathfinder for a large fiber-fed s
 urvey spectrograph but will be a scientific instrument on its own, capable
  of providing high quality science data and be competitive within the inst
 rumentation suite of GTC. A Letter of Intent has been submitted recently t
 o propose miniSIDE as a facility science instrument for GTC.
