Stellar yields and chemical evolution - The solar neighborhood as a calibrator
Daniel Thomas, Laura Greggio, Ralf Bender
Uncertainties in stellar nucleosynthesis and their impact on models of chemical evolution are discussed. Comparing the Type II supernova nucleosynthesis prescriptions from Woosley…
Axisymmetric, 3-Integral Models of Galaxies: A Massive Black Hole in NGC3379
Karl Gebhardt, Douglas Richstone, John Kormendy +8
We fit axisymmetric 3-integral dynamical models to NGC3379 using the line-of-sight velocity distribution obtained from HST/FOS spectra of the galaxy center and ground-based long-sl…
The Low Resolution Spectrograph of the Hobby-Eberly Telescope II. Observations of Quasar Candidates from the Sloan Digital Sky Survey
D. P. Schneider, Gary J. Hill, X. Fan +1
This paper describes spectra of quasar candidates acquired during the commissioning phase of the Low-Resolution Spectrograph of the Hobby-Eberly Telescope. The objects were identif…
The orbital structure and potential of NGC 1399
R. P. Saglia, Andi Kronawitter, Ortwin Gerhard +1
Accurate and radially extended stellar kinematic data reaching R=97'' from the center are presented for the cD galaxy of Fornax, NGC 1399. The stellar rotation is small (<= 30 km/s…
Probing early-type galaxy evolution with the Kormendy relation
B. L. Ziegler, R. P. Saglia, R. Bender +3
We investigate the evolution of early-type galaxies in four clusters at z=0.4 (Abell370, Cl0303+17, Cl0939+47 and Cl1447+26) and in one at z=0.55 (Cl0016+16). The galaxies are sele…
VLT and NTT Observations of Two EIS Cluster Candidates. Detection of the Early-Type Galaxies Sequence at z~1
L. da Costa, M. Scodeggio, L. F. Olsen +7
Optical data from the ESO VLT-UT1 Science Verification observations are combined with near-infrared data from SOFI at the NTT to obtain optical-infrared color-magnitude diagrams fo…
