We have studied the amount of diffuse light in two galaxy groups, Leo and HCG 44 through the detection of intragroup planetary nebulae (IGPNe). The emission...
Digging into the mystery of the Galactic globular clusters M22 and NGC1851
We propose to collect deep near-infrared (NIR) images of two peculiar Galactic globular clusters (GGCs), NGC1851 and M22, to explore the properties of their...
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...
