The radius of these things is proportional to their average effective surface brightness to the power of about negative 0.83. Using a Fourier series to fit the isophotes of these things allows them to be sorted into disky and boxy versions, and they are typically found in the red sequence of the color-magnitude diagram. One named Maffei I is found in the Zone of Avoidance 
The radius of these things is proportional to their average effective surface brightness to the power of about negative 0.83. Using a Fourier series to fit the isophotes of these things allows them to be sorted into disky and boxy versions, and they are typically found in the red sequence of the color-magnitude diagram. One named Maffei I is found in the Zone of Avoidance while a gigantic one near Virgo emits a pair of powerful jets and is designated M87. The velocity dispersion profile of these objects, taken to the fourth power, is proportional to the luminosity according to the Faber-Jackson relation. Eight different types of these galaxies are found on the unbranched section of the Hubble tuning fork. For 10 points, name these galaxies that have an elongated shape.
