In these proceedings we summarize the characteristics and current status of MEGARA, the future optical IFU and MOS for the 10.4 m GTC. MEGARA is being built by...
Modelling astronomical adaptive optics - I. The software package CAOS
The software package CAOS (code for adaptive optics systems) described in this paper is a software ensemble of modules designed for end-to-end simulation of...
Multi-conjugate adaptive optics images of the Trapezium cluster
Context: Multi-conjugate adaptive optics (MCAO) combine the advantages of both standard adaptive optics, which provide high contrast and high spatial resolution...
Multi-instrument measurement campaign at Paranal in 2007. Characterization of the outer scale and the seeing of the surface layer
Aims: Within the framework of site qualification for the future European large telescope E-ELT, a campaign of measurements was carried out for ten nights in...
Multiple reference star differential imaging with VLT/SPHERE: Influence of the reference frame selection and library
Context. High-contrast imaging observations mostly rely on angular differential imaging, a successful technique for detecting point-sources, such as planets...
NAHUAL: a near-infrared high-resolution spectrograph for the GTC optimized for studies of ultracool dwarfs
We present the status of an ongoing study for a high-resolution near-infrared echelle spectrograph for the 10.4-m GTC (Gran Telescopio de Canarias) which will...
Near-infrared polarimetric adaptive optics observations of NGC 1068: a torus created by a hydromagnetic outflow wind
We present J' and K' imaging linear polarimetric adaptive optics observations of NGC 1068 using MMT-Pol on the 6.5-m MMT. These observations allow us to study...
NEFER (Nuevo Espectrómetro Fabry-Pérot de Extrema Resolución) is a 3D instrument aimed to implement high resolution spectrometry for velocity determinations of...
Current polarimetric calibration techniques derive the instrument modulation matrix by numerically fitting an instrumental model to measurements of a set of...
