The Fundamental Plane of Cluster Elliptical Galaxies
Using deep Hubble Space Telescope Advanced Camera for Surveys imaging and Very Large Telescope FOcal Reducer/low dispersion Spectrograph 2 spectra, we determined the velocity dispersions, effective radii, and surface brightnesses for four early-type galaxies in the cluster RDCS 1252.9 2927. All four galaxies are massive, z p 1.237 greater than . These four galaxies, combined with three from RDC...
متن کاملThe Fundamental Scaling Relations of Elliptical Galaxies
We examine the fundamental scaling relations of elliptical galaxies formed through mergers. Using hundreds of simulations to judge the impact of progenitor galaxy properties on the properties of merger remnants, we find that gas dissipation provides an important contribution to tilt in the Fundamental Plane relation. Dissipationless mergers of disks produce remnants that occupy a plane similar ...
متن کاملEvolution of Elliptical Galaxies up to z ≈ 1 ∗
We review the observational evidence showing that luminous cluster elliptical galaxies are old stellar systems, undergoing mostly passive stellar evolution up to redshift z ≈ 1, with approximate coeval epoch of formation. This scenario is supported by observations of local early–types, collected by 2m – 4m class telescopes, and fits the recently gained high resolution imaging (given by the refu...

15 صفحه اولThe z-structure of disk galaxies towards the galaxy planes
Wepresent a detailed study of a statistically complete sample of highly inclined disk galaxies in the near-infraredK ′ band. Since theK ′-band light is relatively insensitive to contamination by galactic dust, we have been able to follow the vertical light distributions all the way down to the galaxy planes. Themean levels for the sharpness of theK ′-band luminosity peaks indicate that the vert...
