A robust morphological classification of high-redshift galaxies using support vector machines on seeing limited images. II. Quantifying morphological k-correction in the COSMOS field at 1<z<2: Ks band vs. I band
M. Huertas-Company, L. Tasca, D. Rouan +10
We quantify the effects of \emph{morphological k-correction} at by comparing morphologies measured in the K and I-bands in the COSMOS area. Ks-band data have indeed the adv…

The achromatic chessboard, a new concept of phase shifter for Nulling Interferometry - I. theory
Daniel Rouan, Didier Pelat
Direct detection of a planet around a star in the mid-IR, requires a nulling interferometer featuring an achromatic phase shift of pi on broad range. A new concept for designing su…
