One of the very interesting discoveries by the Hubble Space Telescope (HST)
is the resolution of circumnuclear star forming regions in several galaxies
into a large number of bright very compact objects, each several hundred
times more luminous than the brightest clusters in the Milky Way. They
have been proposed to be young globular clusters. We discovered 42 such
objects in the nuclear region of the galaxy NGC1365. It turns out that
one of them coincides very closely with one of the brightest compact radio
continuum sources that we have found previously, indicating that this
source is a single object and may belong to the rare class of radio
supernovae. In the [OIII] 
line, the HST also resolves
individual clouds within the conical outflow from the nucleus, some of
which gather in larger agglomerations. From SEST observations of the
nuclear region in the J=3-2 CO emission line we have discovered a
circumnuclear molecular torus. We have ground based observations of
circumnuclear activity also in a number of other galaxies, in particular
NGC1358 for which we have data obtained at NOT and with the ESO 2.2-m
telescope. These data are being reduced.
