MOSAIC is the multi-object fibre spectrograph for ESO's 39-m Extremely Large Telescope (ELT). It offers unique capabilities for a gigantic telescope in terms of multiplexing, wavelength coverage and spectral resolution. MOSAIC covers the visible (0.39-0.95 microns) and NIR (0.95-1.8 microns) wavelength domains, with me...

The SAXO+ system is a planned second-stage Adaptive Optics (AO) upgrade to the VLT/SPHERE eXtreme Adaptive Optics (SAXO) system. This consists of adding a second adaptive optics stage using a near-infrared pyramid wavefront sensor to record images of fainter exoplanets around redder stars. In this work, we compare the...

SAXO+ is the second-stage adaptive optics (AO) system that will be added in cascade after SPHERE’s current extreme AO system at the VLT. This upgrade of SPHERE aims to improve coronagraphic contrast by a factor of 10 or more, close to the star, and to extend the performance to fainter, redder targets. To achieve these...
