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...
A Compact Early-type Galaxy at z = 0.6 Under a Magnifying Lens: Evidence For Inside-out Growth
galaxies elliptical and lenticular cD
2010/11/10
We use Keck laser guide star adaptive optics imaging and exploit the magnifying effects of strong gravitational lensing (the effective resolution is FWHM 200 pc) to investigate the sub-kpc scale of ...
Evidence of major dry mergers at M* > 2 x 10^11 Msun from curvature in early-type galaxy scaling relations?

2010/11/11
For early-type galaxies, the correlations between stellar mass and size, velocity dis-
persion, surface brightness, color, axis ratio and color-gradient all indicate that two mass scales, M∗ = ...
GLOBULAR CLUSTERS AND PLANETARY NEBULAE KINEMATICS AND X–RAY EMISSION IN THE EARLY–TYPE GALAXY NGC 5128
Galaxies kinematics and dynamics-Galaxies elliptical and lenticular, cD-Galaxies structure-dark matter-Galaxies individual (NGC5128)
2009/2/18
The estimates of the mass of the galaxy NGC 5128 based on the
di erent mass tracers, globular clusters (GCs) and planetary nebulae (PNe), are
presented. These estimates are compared with the estimat...
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...
