Se inicia el proceso de planificación para los instrumentos MOS y HIRES a instalarse en el E-ELT

El telescopio más grande del mundo contará con los mejores instrumentos del mundo

23 de Marzo de 2016

Los científicos e ingenieros han comenzado a describir las especificaciones detalladas de dos nuevos instrumentos que serán parte de la instrumentación del futuro European Extremely Large Telescope (E-ELT) de ESO. MOS (el Multi-Object Spectrograph o espectrógrafo multiobjeto) y HIRES (el High Resolution Spectrograph o espectrógrafo de alta resolución) serán los instrumentos principales a nivel mundial instalados en el que será el telescopio más grande del mundo.

El 18 de marzo de 2016, ESO y el CNRS-INSU, la institución principal del consorcio MOSAIC [1], firmaron un contrato para iniciar los estudios de diseño para MOS. El instrumento será capaz de combinar una alta resolución espectral y espacial y llevará a cabo estudios de campo amplio en los segmentos de luz visible y rayos infrarrojos del espectro. Este permitirá a los astrónomos estudiar algunos de los misterios más profundos del Universo: cuándo se formaron las primeras galaxias y cómo se adhirieron a estructuras de gran tamaño como la Vía Láctea; de qué forma se distribuyen la materia ordinaria y la materia oscura a lo largo del Universo; y cómo se forman y evolucionan los planetas alrededor de otras estrellas.

El contrato para iniciar los estudios de diseño para HIRES se firmó el 22 de marzo de 2016, entre ESO y el consorcio HIRES, encabezado por el INAF [2]. HIRES es un espectrógrafo de alta resolución, que opera en longitudes de onda visibles e infrarrojas de manera simultánea. Este se empleará en estudios extremadamente detallados y precisos de objetos individuales. Por ejemplo, permitirá a los astrónomos: estudiar las atmósferas de planetas que orbitan otras estrellas en búsqueda de las firmas espectrales de elementos esenciales para la vida; analizar la evolución de las galaxias; identificar las propiedades espectrales de la primera generación de estrellas en los inicios del Universo; y determinar si algunas de las constantes fundamentales de la física, las que regulan la mayoría de los procesos físicos del Universo, realmente varían con el tiempo.

Los dos consorcios están entre los más grandes que jamás hayan colaborado en la producción de instrumentos astronómicos, lo que demuestra los esfuerzos multinacionales involucrados en la fabricación de estos espectrógrafos.

Instrumentos de este tipo se encuentran en la caja de herramientas fundamental de cada telescopio moderno (estos ejemplos líderes en el mundo sacarán el máximo provecho del enorme poder de recolección de luz del espejo principal de 39 metros del E-ELT, entregándoles un rendimiento sin igual).
