Our March meeting saw Dr David Cole of UCLAN tell us how observations
with the high
resolution instruments from the Hubble Space Telescope have revealed that many low and
intermediate mass galaxies contain a dense star cluster at their centre. These
star clusters are among the densest stellar systems known. They have been found
in galaxies which also have a super-massive black hole at their centre and the
Milky Way is in fact an example of such a system. The formation of these star clusters seems to be intimately related to
the formation of the host galaxy because their properties have a strong relationship to the properties of the host galaxy. |
