In addition to being described by De Vaucouleur's Law and the Faber-Jackson relation, these objects are characterized by being surrounded by a large number of globular clusters and consisting of mainly older, Population II stars.
The two-component nature of these structures in conjunction with their isolation are thought to give rise to the presence of an isophotal twist within inner portions of these structures. The brightness with respect to distance for one of these objects can be found by multiplying its surface brightness by an exponential of the quantity one minus the radius to the one-fourth power. The distance to these objects can be described in a relationship relating their(*) luminosity to some power gamma of the central velocity dispersion. In addition to being described by De Vaucouleur's Law and the Faber-Jackson relation, these objects are characterized by being surrounded by a large number of globular clusters and consisting of mainly older, Population II stars. They compose the handle of "Hubble's Tuning Fork." For 10 points, identify this class of galaxies names for their smooth, elongated shape.
