Massive z ~ 1.3 evolved galaxies revealed
P. Saracco, M. Longhetti, P. Severgnini +8
We present the results of TNG near-IR low resolution spectroscopy of two (S7F5-254 and S7F5-45) sources belonging to a complete sample of 15 EROs with K'<18 and R-K'>5 selected fro…
Kinematics and stellar populations of 17 dwarf early-type galaxies
D. Thomas, R. Bender, U. Hopp +2
We present kinematics and stellar population properties of 17 dwarf early-type galaxies in the luminosity range -14> M_B> -19. Our sample fills the gap between the intensively stud…
Large-Scale Structure in the NIR-Selected MUNICS Survey
C. S. Botzler, J. Snigula, R. Bender +6
The Munich Near-IR Cluster Survey (MUNICS) is a wide-area, medium-deep, photometric survey selected in the K' band. The project's main scientific aims are the identification of gal…
Axisymmetric Dynamical Models of the Central Regions of Galaxies
Karl Gebhardt, Douglas Richstone, Scott Tremaine +12
We present axisymmetric, orbit superposition models for 12 galaxies using data taken with the Hubble Space Telescope (HST) and ground-based observatories. In each galaxy, we detect…
The puzzlingly small CaII triplet absorption in elliptical galaxies
R. P. Saglia, Claudia Maraston, Daniel Thomas +2
We measure the central values (within Re/8) of the CaII triplet line indices CaT* and CaT and the Paschen index PaT at 8600 AA for a 93%-complete sample of 75 nearby early-type gal…
Galaxies with a Central Minimum in Stellar Luminosity Density
Tod R. Lauer, Karl Gebhardt, Douglas Richstone +15
We used HST WFPC2 images to identify six early-type galaxies with surface- brightness profiles that decrease inward over a limited range of radii near their centers. The implied lu…
The slope of the black-hole mass versus velocity dispersion correlation
Scott Tremaine, Karl Gebhardt, Ralf Bender +12
Observations of nearby galaxies reveal a strong correlation between the mass of the central dark object M and the velocity dispersion sigma of the host galaxy, of the form log(M/M_…
The Epochs of Early-Type Galaxy Formation in Clusters and in the Field
Daniel Thomas, Claudia Maraston, Ralf Bender
We compute new population synthesis models of Lick absorption line indices with variable alpha/Fe ratios and use them to derive average ages, metallicities, and alpha/Fe element en…
