The structure of radio galaxies as deduced from HST images

Closely related to the search for molecules near the nuclei of radio galaxies (see the topic "CO", in the menu-bar), is the study of the inner structure of these galaxies. In particular, HST have such a high resolution that we may see dusty features, often in the form of disks, superpose on a galaxy nucleus. This can be easily seen in the HST collection of images that we made about ten years ago. We also collected some information in three tables (HST observing log, radio data and optical dat.
