New Clues on the Nature of Extremely Red Galaxies

A. Cimatti, E. Daddi, S. di Serego Alighieri +7

We present near-infrared VLT-UT1+ISAAC spectroscopy of a sample of 9 extremely red galaxies (ERGs) with R-K>5 and K<19.0. Neither strong emission lines (F_lim<1-5 10^{-16} erg s^{-…

The Star Formation History of Ellipticals from the Fossil Evidence

A. Renzini, A. Cimatti

The current evidence about the age of stellar populations in elliptical galaxies is reviewed. The case for the bulk of stars in galactic spheroids (ellipticals and bulges) having f…

Chemical Evolution on the Scale of Clusters of Galaxies, and Beyond

Alvio Renzini

Clusters of galaxies allow a direct estimate of the metallicity and metal production yield on the largest scale so far. The ratio of the total iron mass in the ICM to the total opt…

Central UV Spikes in two Galactic Spheroids

Michele Cappellari, Francesco Bertola, David Burstein +3

FOS spectra and FOC photometry of two centrally located, UV-bright spikes in the elliptical galaxy NGC 4552 and the bulge-dominated early spiral NGC 2681, are presented. These spec…

The VLT observations of the HDF-S NICMOS field: photometric catalog and high redshift galaxy candidates

A. Fontana, S. D'Odorico, R. Fosbury +6

We present the deep UBVRI observations of the HDF-S NICMOS field obtained as part of the Science Verification of the VLT Unit 1 telescope. The images have been used to construct ob…

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…
