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 ...
Colour gradients in normal and compact early-type galaxies at 1
galaxies elliptical and lenticular CD galaxies formation galaxies: evolution
2010/11/15
We have derived colour gradients for a sample of 20 early-type galaxies (ETGs) at 1 < z
spec < 2 selected from the GOODS-South field. The sample includes both nor-mal ETGs (13) having effective radii...
