Líneas de instrumentación: Instrumentación infrarroja

Instrumentación infrarroja

La instrumentación para detectar y analizar la luz en el rango infrarrojo del espectro es uno de los campos de conocimiento del Área de Instrumentación. El diseño y construcción de cámaras y espectrógrafos infrarrojos requiere de tecnologías del alto vacío y criogenia, que abarcan las especialidades de la ingeniería mecánica, óptica y electrónica, principalmente. La integración y funcionamiento de mecanismos y dispositivos en criogenia es especialmente compleja y exige unos conocimientos y equipamiento altamente especializados. El Área de Instrumentación tiene una larga historia de participación internacional en este tipo de instrumentación.

    The return of FarNet-II: Generation of solar far-side magnetograms from helioseismic data
    Context. The far-side activity of the Sun can be inferred by interpreting the near-side wave field using local helioseismic techniques. However, detections are...

    The role of cooling induced by mixing in the mass and energy cycles of the solar atmosphere
    In many astrophysical systems, mixing between cool and hot temperature gas/plasma through Kelvin-Helmholtz-instability-driven turbulence leads to the formation...

    The role of grain size in active galactic nuclei torus dust models
    Context. Active galactic nuclei (AGN) are surrounded by dust within the central parsecs. The dusty circumnuclear structures, referred to as the torus, are...

    The role of the chromospheric magnetic canopy in the formation of a sunspot penumbra
    Context. While it is conjectured that a chromospheric canopy plays a role in penumbra formation, it has been difficult to find observational evidence of the...

    The role of the Lorentz force in sunspot equilibrium
    Context. Sunspots survive on the solar surface for timescales ranging from days to months. This requires them to be in an equilibrium involving magnetic fields...

    The signature of chromospheric heating in Ca II H spectra
    Context: The heating process that balances the solar chromospheric energy losses has not yet been determined. Conflicting views exist on the source of the...
