A dust bubble within the globular cluster NGC 6624?

A multi-color analysis of CCD frames and polarimetry for both dark patches and stars in the field of the globular cluster NGC 6624 is presented. Several of these patches have a wavelength behavior that is consistent with the existence of intra-cluster dust. The spatial distribution of these patches...
