SPIDER - V. Measuring Systematic Effects in Early-Type Galaxy Stellar Masses from Photometric SED Fitting
Measuring Systematic Effects Early-Type Galaxy Stellar Masses Photometric
2011/10/17
We present robust statistical estimates of the accuracy of early-type galaxy stellar masses derived from spectral energy distribution (SED) fitting as functions of various empirical and theoretical as...
THE TOTAL MASS OF THE EARLY-TYPE GALAXY NGC 4649 （M60）
Gravitation-Galaxies elliptical and lenticular, cD-Galaxies kine-matics and dynamics-Galaxies: individual NGC 4649 Cosmology dark matter
2009/1/15
In this paper the problem of the total mass and the total mass-to-
light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two
independent techniques: the X-ray methodology w...
