The Coma cluster luminosity function from ultraviolet to near-infrared
S. Andreon, J. -C. Cuillandre, R. Pello
[Abridged] The Coma cluster luminosity function (LF) from ultraviolet (2000 AA) to the near-infrared (H band) is summarized. In the UV the LF is very steep, much steeper than in th…
Spectroscopic follow up of arclets in AC114 with the VLT
J. F. Le Borgne, L. Campusano, R. Pello +5
We present the first results on the VLT/FORS-1 spectroscopic survey of amplified sources and multiple images in the lensing cluster AC114. Background sources were selected in the c…
Photometric Redshifts and Gravitational Telescopes
R. Pello, M. Bolzonella, J. F. Le Borgne +8
We review the use of photometric redshifts in the particular context of Gravitational Telescopes. We discuss on the possible application of such a technique to the study of both th…
Quasar Candidate Multicolor Selection Technique: a different approach
E. Hatziminaoglou, G. Mathez, R. Pello
We present a quasar candidate identification technique based on multicolor photometry. The traditional multi-dimensional method (2 N dimensions, where N is the number of t…
