... M89 a relatively obscure elliptical galaxy in the Virgocluster was observed for 992 seconds in B1 and 496 seconds in A1. ... M87 is the brightest galaxy in the Virgocluster and is among the most massive of all galaxies known. ...
... This is because M90 is a member of the VirgoCluster and its random velocity due to the gravitational potential well of Virgo is larger than its relative expansion velocity with respect to the Milky Way. ...
... Recent surveys of the Virgocluster by Impey et al. (1988) and of the Fornax cluster ... LSB galaxies in Virgo steepened the lowluminosity tail of that cluster's luminosity ...
... We discuss how the neutron stars in the VirgoCluster are modeled and the use of radiometry to search for their stochastic GW signature in LIGO-VIRGO data. ...
... UIT failed to obtain a deep field in Virgo centered on a LSB galaxy there but did succeed in obtaining several good exposures of galactic Globular Clusters as well as a field in M31. ...
