Descripción
We summarise some recent results about nearby galactic bulges, relevant
to their formation. We highlight a number of significant advances in our
understanding of the surface brightness profiles, stellar populations,
and especially the very centers of spirals. We also view our own Milky
Way as if it were an external galaxy. Our main conclusions are that
bulges of early-type spirals (Sb or earlier) contain central point
sources, just like late-type spirals and most other types of galaxies.
Central point source luminosities correlate best with total bulge
luminosity, and not as well with morphological type. Bulges of
early-type spiral galaxies follow the fundamental plane and the
colour/line strength vs. luminosity relations of elliptical galaxies.
Although we have a reasonable idea about bulges of early-type spirals we
know much less about late-type bulges. However, the close resemblance of
our Milky Way Bulge to early-type external bulges makes us suspect that
maybe bulges of late-type spirals might be very similar as well.
