Looking for fine structures in galaxies.

FAUNDEZ-ABANS M. and DE OLIVEIRA-ABANS M.

Abstract (from CDS):

In order to enhance fine structure in direct CCD images of galaxies, transform processing has been employed: working in the transform domain, transform functions have been created and simple high- and low-pass filters have been applied to the images during the process. The results presented herein refer to a test sample of four galaxies: ESO 143-G7, HRG 54103, NGC 5193/5193A, and NGC 5761. It is also discussed the use of a Fourier-hologram image as a transfer function.
