ESO Imaging Survey. Deep Public Survey: Infrared Data for the Chandra Deep Field South

B. Vandame, L. F. Olsen, H. E. Jorgensen +12

This paper presents new J and Ks near-infrared data obtained from observations of the Chandra Deep Field South (CDF-S) conducted at the ESO 3.5m New Technology Telescope (NTT). The…

Spectroscopic confirmation of clusters from the ESO imaging survey

M. Ramella, A. Biviano, W. Boschin +8

We measure redshifts for 67 galaxies in the field of six cluster candidates from the ESO Imaging Survey (EIS). The cluster candidates are selected in the EIS patches C and D among…

Building a Sample of Distant Clusters of Galaxies

L. da Costa, M. Scodeggio, L. F. Olsen +1

Candidate clusters of galaxies drawn from the sample identified from the moderately deep I-band data of the ESO Imaging Survey (EIS), have been used for follow-up optical/infrared…

Confirming EIS Clusters. Multi-object Spectroscopy

A. Biviano, M. Ramella, W. Boschin +7

Using EFOSC2 at the 3.6m ESO telescope, we obtained redshifts for 68 galaxies in the field of six cluster candidates from the ESO Imaging Survey (EIS). The cluster candidates were…

Confirming EIS Clusters. Optical and Infrared Imaging

L. F. Olsen, H. E. Jorgensen, M. Scodeggio +6

Clusters of galaxies are important targets in observationally cosmology, as they can be used both to study the evolution of the galaxies themselves and to constrain cosmological pa…

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…
