Surface brightness fluctuations of Fornax cluster galaxies: calibration of infrared surface brightness fluctuations and evidence for recent star formation.
LIU M.C., GRAHAM J.R. and CHARLOT S.
Abstract (from CDS):
MKS=(-5.84±0.04)+(3.6±0.8)[(V-Ic)0-1.15],
valid for 1.05<(V-Ic)0<1.25 and not including any systematic errors in the HST Cepheid distance scale. The fit accounts for the covariance between V-Ic and MKS when calibrated in this fashion. The intrinsic cosmic scatter of MKS appears to be larger than that of I-band SBFs. S0 galaxies may follow a different relation, although the data are inconclusive. The discovery of correlation between K_S_-band fluctuation magnitudes and colors with V-Ic is a new clue into the star formation histories of early-type galaxies. This relation naturally accounts for galaxies previously claimed to have anomalously bright K-band SBFs, namely, M32 and NGC 4489. Models indicate that the stellar populations dominating the SBF signal have a significant range in age; some scatter in metallicity may also be present. The youngest ages imply some galaxies have very luminous giant branches, akin to those in intermediate-age (few Gyr) Magellanic Cloud clusters. The inferred metallicities are roughly solar, although this depends on the choice of theoretical models. A few Fornax galaxies have unusually bright KS-band SBFs, perhaps originating from a high-metallicity burst of star formation in the last few Gyr. The increased spread and brightening of the KS-band SBFs with bluer V-Ic suggest that the lower mass cluster galaxies (≲0.1L*) may have had more extended and more heterogeneous star formation histories than those of the more massive galaxies.
