Abstract | K band (2.2 micron) photometry is reported for selected positions near the east-west axis of the giant elliptical galaxy M87. The data are consistent with B band profiles. The luminosity profile is compared with the density profile derived from X-ray measurements. If a correction is made for the light of the known stellar component, the remaining 'dark matter' has a mass-to-light ratio of M/L greater than 100 (2 sigm ... |
