The popularization of science, as a part of Culture, has and continues to be a constant concern for the Instituto de Astrofísica de Canarias (IAC), reflected in...
DIORAMAS: a wide-field visible and near-infrared imaging multi-slit spectrograph for the EELT
We present the science, design and performances of DIORAMAS, an imager and multi-slit spectrograph for the European Extremely Large Telescope. It covers a wide...
DIPSI: measure of the tip-tilt with a diffraction image phase sensing instrument
Large segmented mirrors require efficient co-phasing techniques in order to avoid the image degradation due to segments misalignment. DIPSI (Diffraction Image...
DIPSI: the diffraction image phase sensing instrument for APE
Large segmented mirrors require efficient co-phasing techniques in order to avoid the image degradation due to segments misalignment. For this purpose in the...
Since the discovery in 1995 of the first extrasolar planet candidate around a solar type star using the radial velocity method, to date (beginning of 2005), 135...
Direct Imaging and Spectroscopy of a Young Jupiter-like Object
We report on our continuing effort to identify extremely low-mass members of the cluster around the hot star sigma Orionis. Using the KeckI telescope in Hawaii...
Direct imaging of haloes and truncations in face-on nearby galaxies
We use ultra-deep imaging from the IAC Stripe 82 Legacy Project to study the surface photometry of 22 nearby, face-on to moderately inclined spiral galaxies...
