Abstract:
We present results from ground based VLT/FLAMES spectroscopy in
combination with HST data for six Galactic globular clusters. The aim
of this work is to probe whether these massive clusters host an
intermediate-mass black hole at their center using analytical Jeans
models.
Description:
We matched the reconstructed ARGUS pointings with the HST image and
created a combined ARGUS cube. The first two dimensions are measured
in RA and DEC and the third dimension in wavelength (nm). A header
with the most important keywords is also given.
