What would a 35m-scale narrow field-of-view telescope look like that is designed for high dynamic range direct imaging science? The EU has charged the IAC in a 5 year program to explore and develop the concepts and technologies that could make such a ground-based telescope possible. From tensegrity mechanics to astrophotonic wavefront sensing and control in Fizeau optics, the IAC and IACTEC "Laboratory for Innovation in Optomechanics (LIOM)" is just now starting these research activities. This talk will outline the motivation, concepts, and prototypes that LIOM and the IAC will advance over the next few years.

Until relatively recently, high-resolution infrared spectrographs could examine only tiny portions of individual spectral windows in a single exposure.  Silicon immersion gratings, combined with sensitive, large-format IR detectors have made it possible to observe broad swaths of the IR at once at very high resolution and to do so on much fainter systems.  We discuss the development of Si diffractive optics and of the H and K spectrograph IGRINS (now in use on the Gemini South Telescope) and the Giant Magellan Telescope Infrared Spectrograph, which will observe from 1.08 μm to 5.4 μm at R=λ/Δλ=65,000-85,000 in a single exposure.  We present results from IGRINS that demonstrate its sensitivity and versatility as it sheds new light on the atmospheres of exoplanets and cool brown dwarfs, on the evolution of YSO’s and on the physics of the ISM.

The Webb Telescope, the next flagship astrophisical mission from NASA, ESA and the CSA, will be launch on December 18th 2021. With a 6.5 m primary mirror, it harbors 4 state-of-the-art instruments with powerful spectroscopic, imaging and coronagraphic capabilities. During Cycle 1 more than 10000 hours of observing time have been allocated to 400 programs and over 2500 worldwide researchers. From the epoch of reinonization and the evolution of galaxies, to studies of the interestellar medium, evolved stars, debris disks and planetary atmospheres, nearly every area of astrophysics and planetary astronomy are already represented in the first year of observations. This contribution will explore Webb's main areas of studies in Cycle 1, that will certainly open a new space for astrophysical discovery.

The MAGIC telescopes are a stereoscopic system
of two 17m mirror diameter Cherenkov telescopes for gamma-ray observations, in operation since many years on the island of
La Palma at the Observatorio del Roque de los Muchachos.
A new installation allows us to use those telescopes as optical
intensity interferometer which enables us to measure the size of bright
objects in the range of 0.6-1.5 milli-arcsec and other physical
parameters. In this presentation the setup is explained, our physics
targets, first results and also a future outlook of this project
with respect to the Cherenkov telescope array (CTA) currently
in construction.

The "Asteroid Terrestrial-impact Last Alert System" (ATLAS) is funded by NASA to find dangerous asteroids before they strike the Earth. It has operated from two Hawaii sites since 2015 and will very soon have South Africa and Chile sites to cover the entire visible sky every night four times to a limiting magnitude of m~19.5 per exposure. The process of finding asteroids leads to auxiliary data products along the way including accurate photometry of all stars in the sky and detection of flares and transients.  I will describe ATLAS, how we approach our NASA mission to find NEOs, how ATLAS fits in with other ongoing or planned surveys, some of the data products that are available now, and the many new scientific opportunities that are emerging and waiting to be exploited.  Time will be reserved at the end of the talk for some real time demonstrations: audience participation is encouraged.  References include 2018PASP..130f4505T, our public web page at and to see our current fisheye and webcam views at all four sites.

En la presente charla hablaremos de la sobre la actualización que se está llevando a cabo en el software de control del Instrumento Gris de Gregor y como se ha intentado poner en marcha un sistema de integración continua. Además, se comentará la idea de montar un banco polar basado en un sistema de integración continua.

The search for extrasolar planets is one of the fastest-growing fields of astronomy. This rapid growth was both made possible by the development of instrumentation and motivated it, creating a virtuous cycle that impacted positively several fields of research.

In this talk I will present the latest planet-hunting spectrograph ESPRESSO, installed at ESO's VLT. Targeting a radial velocity precision of 10 cm/s, ESPRESSO has the declared goal of detecting an Earth-mass planet inside the habitable zone of a main-sequence dwarf star. I will discuss the first results, ongoing campaigns, and reveal a bit of what the future holds for us.

La gestión de documentos es una tarea compleja que implica múltiples cuestiones, especialmente en proyectos como la definición y creación de un telescopio.  Una correcta gestión documental requiere entre otras cuestiones:

  • Ser fuente única de verdad: Los documentos deben gestionarse desde un punto central que actúe como fuente única de verdad permitiendo la localización y actualización de los mismos.
  • Permitir búsquedas ágiles, simples y eficaces: Aunque el volumen de documentos sea elevado las búsquedas deben mantenerse ágiles y sencillas permitiendo localizar los documento en base a sus características o a la información que contienen.
  • Facilitar la coherencia de formato: Los documentos creados en un proyecto deben mantener un formato y esquema coherente mediante la utilización de plantillas.
  • Agilizar la creación de documentos: La solución debe permitir la creación de nuevos documentos de forma sencilla realizando de forma automatizada tantas tareas como sea posible (codificación, pre-formateo del documento,...).
  • Gestión bibliográfica: los documentos requieren de un mecanismo de codificación que permita la identificación de los mismos.
  • Permitir versionado de documentos: Los documentos evolucionan a lo largo de su ciclo de vida dando lugar a versiones que deben ser almacenadas e identificadas.

Las plataformas de gestión documental existentes "out of the box" no cubren el 100%  de estos requisitos. Sin embargo, ofrecen mecanismos de extensión que permiten ampliar sus capacidades. Desde la oficina de proyecto del EST hemos desarrollado una herramienta para la gestión de los documentos del proyecto,  a partir de soluciones libres como Alfresco o, que cubre todas estas necesidades.

Al objeto de incrementar la cobertura de cielo proporcionada por el sistema de óptica adaptativa de GTC, durante los últimos 4 años se ha estado trabajando en la incorporación de un sistema de estrella guía láser de Sodio. A través de esta charla se repasará el estado actual del proyecto enfatizando aquellos aspectos relacionados con el sistema óptico de lanzamiento de la estrella guía.
