Abstract:
This paper presents Gemini-gri' high-quality photometry for cluster
candidates in the field of NGC 1316 (Fornax A) as part of a study that
also includes GMOS spectroscopy. A preliminary discussion of the
photometric data indicates the presence of four stellar cluster
populations with distinctive features in terms of age, chemical
abundance and spatial distribution. Two of them seem to be the usually
old (metal poor and metal rich) populations typically found in
elliptical galaxies. In turn, an intermediate-age (5 Gyr) globular
cluster population is the dominant component of the sample (as
reported by previous papers). We also find a younger cluster
population with a tentative age of ~=1Gyr.
Description:
The data set used in this work was observed in image mode with the
GMOS camera, mounted on Gemini South telescope, between 2008
September-October and 2009 August-October (Programmes
GS-2008B-Q-54 and GS-2009B-Q-65, PI: J.C. Forte).
Four images per field with a binning of 2x2 were taken through SDSS
g', r' and i' filters.
The magnitudes and colours, corrected for interstellar extinction, for
all sources detected by SExtractor in NGC 1316 are given in Table 2.
