The Arizona-New Mexico spectroscopic survey of galaxies. II. Structures inthe Perseus supercluster

Using new redshift data reported in Gregory et al., we examine the structur e of the Perseus supercluster. We discuss in detail three filaments lying i n the plane of the sky on the western end of the supercluster that are dist inct from each other in redshift and/or position. Additionally, radially di rected filaments are found, and it appears that all of the filaments in the region are connected. We speculate that an important feature of filamentar y structures may be the fact that many, if not all of them, connect in such a way as to form complete loops or rings. Underdense regions that border o ur filaments may not be very representative of the now classical cosmic voi d, in that their structures are not predominantly spheroidal.
