Title: Star Formation History of Carina Dwarf Galaxy

Abstract:
We present spatially resolved star formation history (SFH) of Carina dwarf spheroidal galaxy. 
This was obtained with deep/wide g-r v/s g color-magnitude diagrams (CMDs) combined with 
spectroscopically determined metallicity distributions functions (MDFs) of red giant branch 
stars. The photometrical coverage is ~2 deg square, reaching up to ~10 times the half light 
radius of the galaxy with completness levels higher than 50% at ~24.5 in g, which is more than 
one magnitude fainter than the oldest turnoff. This is the first time a combination of deepness 
and coverage of this quality is used to derive the SFH of Carina, enabling us to trace its different 
populations at unpreceded accuracy. The SFH was determined using Talos routine, which 
compares the observed CMD and MDF with the ones obtained from a linear combination of 
synthetic populations. The models include several observational effects such as reddening, 
completness, photometric errors and binarity, making them directly comparable to data. This 
procedure enable us to use all the information from the CMDs (and not just specific features 
from it) as well as the spectroscopically derived MDFs which helps considerably to constrain 
results that could be otherwise degenerated. 
I will present the main results about this work as well the consequences it imposes to the early 
formation of Carina and its interaction with the Milky Way.
