Abstract:
Current stellar population models have arguably the largest
uncertainties in the near-IR wavelength range, partly due to a lack of
large and well calibrated empirical spectral libraries. In this paper
we present a project whose aim it is to provide the first library of
luminosity weighted integrated near-IR spectra of globular clusters
to be used to test the current stellar population models and serve
as calibrators for future ones. Our pilot study presents spatially
integrated K-band spectra of three old (≥10Gyr) and metal poor
([Fe/H]~-1.4), and three intermediate age (1-2Gyr) and more metal
rich ([Fe/H]~-0.4) globular clusters in the LMC.
Description:
Provided are spatially integrated K-band spectra of LMC globular
clusters in the wavelength range 1.92-2.45 microns. The spectra are
obtained using the IFU spectrograph SINFONI mounted on the VLT. A
detailed description of the integration process can be found in the
paper.
