B2 0902+34: a Collapsing Protogiant Elliptical Galaxy at Z=3.4
We have used the visible integral-field replicable unit spectrograph prototype (VIRUS-P), a new integral field spectrograph, to study the spatially and spectrally resolved Lyman-α emission line structure in the radio galaxy B2 0902+34 at z = 3.4. We observe a halo of Lyman-α emission with a velocity dispersion of ≈250 km s−1 extending to a radius of 50 kpc. A second feature is revealed in a spa...
متن کاملThe Elliptical–Spheroidal and Elliptical–Elliptical Galaxy Dichotomies
This paper summarizes Kormendy et al. (2009, ApJS, in press, arXiv:0810.1681). We confirm that spheroidal galaxies have fundamental plane correlations that are almost perpendicular to those for bulges and ellipticals. Spheroidals are not dwarf ellipticals. They are structurally similar to late-type galaxies. We suggest that they are defunct (“red and dead”) late-type galaxies transformed by a v...
متن کاملDiscovery of a Galaxy Responsible for a DLA System atz = 3 : 15 and a Near -
We report the detection, both in line and continuum emission, of a galaxy responsible for a damped Ly absorption (DLA) system at z = 3:15 projected 2:3 00 from QSO 2233+131. The star formation rate implied by both the Ly and restframe far-UV continuum is 7 M yr ?1. The galaxy also shows no sign of an active nucleus and has blue colors, both consistent with it being observed early in its star fo...
متن کاملElliptical Galaxy Dynamics: the Issues Pertaining to Galaxy Formation
How elliptical galaxy dynamics relate to galaxy structure, stellar populations, spiral galaxies and environment are reviewed. The evidence assembled shows that most, if not all, galaxies originally classified as gE contain disks within them. Taken together, the existing evidence are most consistent with the gravitational, hierarchical, clustering, merging (HCM) concept that all galaxies, includ...
متن کاملStellar Population Diagnostics of Elliptical Galaxy Formation
Major progress has been achieved in recent years in mapping the properties of passively-evolving, early-type galaxies (ETG) from the local universe all the way to redshift ∼ 2. Here, age and metallicity estimates for local cluster and field ETGs are reviewed as based on color-magnitude, color-σ, and fundamental plane relations, as well as on spectral-line indices diagnostics. The results of app...
