Halpha emitting galaxies and the cosmic star formation rate at z = 2.2
Alan F. M. Moorwood, Paul P. van der Werf, Jean Gabriel Cuby +1
About 10 candidate Halpha emitting galaxies at z = 2.2 have been detected in a 2.1 um narrow band imaging survey covering an area of 100 sq. arcmin including the WFPC2 and STIS fie…
A search for clusters at high redshift - II. A proto cluster around a radio galaxy at z=2.16
L. Pentericci, J. D. Kurk, H. J. A Rottgering +7
VLT spectroscopic observations of Ly alpha--excess objects in the field of the clumpy radio galaxy 1138-262 at z=2.16 have led to the discovery of 14 galaxies and one QSO at approx…
An excess of mid-IR luminous galaxies in Abell 1689?
D. Fadda, D. Elbaz, P. -A. Duc +4
We present the results of infrared observations of Abell 1689 which was observed with ISOCAM, at 6.7\mic and 15\mic, and ISOPHOT at 200\mic. The cluster galaxies detected above a s…
Search for clusters at high redshift - I. Candidate Lya emitters near 1138-262 at z=2.2
J. D. Kurk, H. J. A. Rottgering, L. Pentericci +7
Radio, optical and X-ray observations of the powerful radio galaxy PKS 1138-262 at z=2.156 have suggested that this galaxy is a massive galaxy in the center of a forming cluster. W…
The extragalactic background and its fluctuations in the far-infrared wavelengths
G. Lagache, J-L. Puget, A. Abergel +22
A Cosmic Far-InfraRed Background (CFIRB) has long been predicted that would traces the intial phases of galaxy formation. It has been first detected by Puget et al.(1996) using COB…
Discovery of a faint Field Methane Brown Dwarf from ES0 NTT and VLT observations
J. G. Cuby, P. Saracco, A. F. M. Moorwood +4
We report the discovery of an isolated brown dwarf with similar properties to the binary object Gliese 229B and to the newly discovered field brown dwarf SDSS 1624+00. Although exh…
