The Extended Local Group of Galaxies
This is an attempt to visualize the appearance of the Extended Local Group of galaxies. The galaxies are shown in supergalactic cartesian coordinate system (the axis are SGX, SGY, and SGZ). Units are in kiloparsecs, which means the whole depicted box is 6.5 by 6.5 megaparsecs in area and three megaparsecs high. The supergalactic plane is shown as a grey plane across the drawing.The location of each galaxy is depicted in two ways: if a galaxy is above the supergalactic plane, then it has a greenish line under it showing how high it is from the plane and if the galaxy is below the supergalactic plane, it has a blueish line above it showing how far below the plane the galaxy is. Each galaxy is also projected to SGX-SGY plane, SGX-SGZ plane, and SGY-SGZ plane. The projection is shown with a light blue dot on the plane for galaxies under the supergalactic plane and with a light green dot for galaxies above the supergalactic plane. There is also a dark blue line connecting the galaxy to these dots. Unfortunately the density of the lines is so high in certain areas that it is difficult to distinguish them from each other. The size and shading of the galaxies is supposed to assist the 3D impression. The larger and brighter red the galaxy appears on the image, the closer it is to the viewer. Actual sizes of galaxies are so small that most of the galaxies would not be visible at all in this image.
