We have measured the line-of-sight velocity distribution from integrated stellar light at two points in the outer halo of M87 (NGC 4486), the second-rank galaxy in the Virgo Cluster. The data were taken at R = 480'' (∼41.5 kpc) and R = 526'' (∼45.5 kpc) along the SE major axis. The second moment for a non-parametric estimate of the full velocity distribution is 420 ± 23 km s{sup –1} and 577 ± 35 km s{sup –1}, respectively. There is intriguing evidence in the velocity profiles for two… CONTINUE READING
