Descripción
The authors have mapped the nearby flocculent spiral galaxy in the
visible U, B and V bands, as well as in the near infrared J, H and K
bands, with a linear resolution of 900 pc. The galaxy is found to have
two principal current centres of large-scale star formation, signposted
by centres of ultraviolet and blue flux. One is in the nucleus, defined
by the geometrical centre of the H I emission, and the other at some 1.5
kpc radial distance away. The outer star-forming region is the more
intense and the younger of the two, and corresponds to a local peak in
the H I surface density. The authors use the colours of the star-forming
regions and of the integrated galaxy to make a first order estimate of
the stellar population distribution.
