EROs found behind lensing clusters: II.Empirical properties, classification, and SED modelling based on multi-wavelength observations
A. Hempel, D. Schaerer, E. Egami +5
We study the properties and nature of extremely red galaxies (ERO, R-K>5.6) found behind two lensing clusters and compare them with other known galaxy populations. New HST/ACS obse…
A Hubble Space Telescope Lensing Survey of X-ray Luminous Galaxy Clusters: II. A Search for Gravitationally Lensed EROs
Graham P. Smith, Ian Smail, Jean-Paul Kneib +7
We present the results of a survey for Extremely Red Objects (EROs) in the fields of ten galaxy cluster lenses at z~0.2, combining high-resolution Hubble Space Telescope imaging wi…
Probing distant galaxies with lensing clusters
Roser Pello
Clusters of galaxies as gravitational lenses allow to study the stellar content and properties of high-z galaxies much fainter than the usual spectroscopic field surveys. We review…
Identification of a Gravitationally Lensed z=2.515 Star-Forming Galaxy
T. M. D. Ebbels, J. -F. Le Borgne, R. Pelló +4
We discuss the optical spectrum of a multiply-imaged arc resolved by HST in the =0.175 cluster A2218. The spectrum, obtained with LDSS-2 on the 4.2m William Herschel telescope,…
