Descripción
We present new results of a long-term investigation of the stellar
content of the Large and the Small Magellanic Cloud. The main aim of the
project is to obtain a comprehensive knowledge of the star formation
history of these two nearby galaxies. Here we discuss the latest
findings obtained using new data and a variety of different
observational approaches, based on wide-field ground-based photometry
and low-resolution CaT spectra. We find evidence of two main star
formation events across the LMC disk. We also found evidence that the
young and intermediate age population (<5 Gyr) presents a steeper
gradient with radius than the old one (>8 Gyr). In particular, the
young (<2 Gyr) component seems to extend to 8 degrees from the
center, distance at which it decreases abruptly. At larger distance, the
old population dominates, extending to at least 13.5 kpc. We also report
the discovery of a population of stars located across the Magellanic
Bridge, compatible with the old population of the LMC.
