LIRIS is a near-IR intermediate resolution spectrograph with added capabilities for multi-object, imaging, coronography, and polarimetry. This instrument is now being constructed at the IAC, and upon complexion will be installed on the 4.2m William Herschel Telescope at the Observatorio del Roque de Los Muchachos. The optical system uses lenses and

Let $B$ be a C$^*$-algebra and $X$ a C$^*$ Hilbert $B$-module. If $pin B$ is a projection, denote by $S_p ={xin X : x,x> =p}$, the $p$-sphere of $X$. For $phi$ a state of $B$ with support $p$ in $B$ and $xin S_p$, consider the state $phi_x$ of $L_B(X)$ given by $phi_x(t)= phi( x,t(x)>)$. In this paper we study certain sets associated to these

The purpose of the Gran Telescopio de CANARIAS (GTC) project is the design, construction, erection and startup of a telescope with a segmented primary mirror equivalent to a circular aperture of 10 m in diameter. The GTC project was created to satisfy the needs of Spanish astronomers for more telescope time and larger telescopes. The GTC project

The GTC (Gran Telescopio Canarias) Project, a 10 meter segmented telescope to be installed at the ORM in La Palma, Spain, is moving forward at full steam. Main science drivers for the GTC are image quality, operational efficiency and reliability. First light is planned for end-2002.

The GTC Dome is entering into manufacture. Once the design has been frozen, it is time to expose the main features of the Dome and to exhibit the key aspects that will introduce an improvement on the GTC performance with respect to existing telescopes. The implementation of the natural ventilation for the telescope chamber, the use of an improved

The presentation summarizes the status of the first generation of instruments for the 10-m Spanish Telescope, GTC. The GTC is planned to have its first light at the end of 2002, and to be operating at the end of 2003. The management plan at the Project Office, PO, for the procurement of the instruments is presented.
