Resumen:
We present results from a wide-field deep photometric study of the globular cluster system(GCS) hosted by NGC 1172. The data are a combination of GMOS (Gemini South) images, and NIR observations obtained with FourStar (LCO). We obtain complete areal coverage of the GCS, which allows us to examine its full extension, combining optic and NIR data in order to deepen our understanding of the galaxy?s properties. Given its location in a very low-dense environment, NGC 1172 proves to be an interesting case since it appears to host a heavily populated GCS, rare for field ellipticals. The results also hint at the potential presence of a third subpopulation, in addition to the conventional ?red? and ?blue? ones, which is a substantial clue for figuring out its evolutionary history.
