A multi-wavelength survey of AGN in the XMM-LSS field: I. Quasar selection via the KX technique
Th. Nakos, J. P. Willis, S. Andreon +16
AIMS: We present a sample of candidate quasars selected using the KX-technique. The data cover 0.68 deg^2 of the X-ray Multi-Mirror (XMM) Large-Scale Structure (LSS) survey area wh…
Biomarkers in disk-averaged near-UV to near-IR Earth spectra using Earthshine observations
Slim Hamdani, Luc Arnold, C. Foellmi +6
We analyse the detectability of vegetation on a global scale on Earth's surface. Considering its specific reflectance spectrum showing a sharp edge around 700 nm, vegetation can be…
Multi wavelength study of the gravitational lens system RXS J1131-1231: II Lens model and source reconstruction
J. -F. Claeskens, D. Sluse, P. Riaud +1
High angular resolution images of the complex gravitational lens system RXS J1131-1231 (a quadruply imaged AGN with a bright Einstein ring) obtained with the Advanced Camera for Su…
Near-UV to near-IR disk-averaged Earth's reflectance spectra
S. Hamdani, L. Arnold, C. Foellmi +5
We report 320 to 1020nm disk-averaged Earth reflectance spectra obtained from Moon's Earthshine observations with the EMMI spectrograph on the NTT at ESO La Silla (Chile). The spec…
