Globular Clusters

[jaehacker]

Just wondering,,, if Sigma is the ratio of the size of a black hole to the speed of the outer stars in a galaxy, do Globular Clusters have black holes? And if they do, why are they not spirals?

Globular Clusters are part of our Milky Way Galaxy. They float above and below the galactic plane. They have a Black Hole.....the same one that is in the center of our galaxy.<br /><br />There is/was a thought that globular cluster got togather to form galaxies.<br /> <div class="Discussion_UserSignature"> <font size="1" color="#3366ff">www.siriuslookers.org</font> </div>

They're called mid-sized blackholes. They're between 10-100 solar masses (from a Sky and Telescope article a few years ago).<br /> <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>
