Young globular clusters in NGC 1316
  We present multi-object spectroscopy of the inner zone of the globular
cluster (GC) system associated with the intermediate-age merger remnant NGC
1316. Using the multi-object mode of the GMOS camera, we obtained spectra for
35 GCs. We find pieces of evidence that the innermost GCs of NGC 1316 rotate
almost perpendicular to the stellar component of the galaxy. In a second stage,
we determined ages, metallicities and {\alpha}-element abundances for each GC
present in the sample, through the measurement of different Lick/IDS indices
and their comparison with simple stellar population models. We confirmed the
existence of multiple GC populations associated with NGC 1316, where the
presence of a dominant subpopulation of very young GCs, with an average age of
2.1 Gyr, metallicities between -0.5 < [Z/H] < 0.5 dex and {\alpha}-element
abundances in the range -0.2 < [{\alpha}/Fe] < 0.3 dex, stands out. Several
objects in our sample present subsolar values of [{\alpha}/Fe] and a large
spread of [Z/H] and ages. Some of these objects could actually be stripped
nuclei, possibly accreted during minor merger events. Finally, the results have
been analyzed with the aim of describing the different episodes of star
formation and thus provide a more complete picture about the evolutionary
history of the galaxy. We conclude that these pieces of evidence could indicate
that this galaxy has cannibalized one or more gas-rich galaxies, where the last
fusion event occurred about 2 Gyr ago.
