Descripción
We present TUNIS, a double-pass spectro-imager built in THEMIS as a proof-of-concept for EST. Basic concepts and selected first results are shown. We introduce the concept of a Hadamard spectral mask as a proposition to move forward from the present implementation of a single-wavelength per image pixel to a more general one of multiplexed spectral information that improves the temporal coherence of the spectral measurement.

Magnetismo, Polarización y Transferencia Radiativa en Astrofísica
Los campos magnéticos están presentes en todos los plasmas astrofísicos y controlan la mayor parte de la variabilidad que se observa en el Universo a escalas temporales intermedias. Se encuentran en estrellas, a lo largo de todo el diagrama de Hertzsprung-Russell, en galaxias, e incluso quizás en el medio intergaláctico. La polarización de la luz

    ALISIO-1 mission: bridging space and Earth with next-generation CubeSat for optical communications and environmental monitoring
    ALISIO-1, the first satellite owned and led by the Instituto de Astrofısica de Canarias (IAC), represents a significant milestone in the space exploration of the Canary Islands. This 6U CubeSat, whose platform has been developed by Open Cosmos, carries two novel payloads: DRAGO-2 and CubeLCT. DRAGO-2, a Short-Wavelength Infrared (SWIR) camera, is

    From atmospheres to exospheres in exoplanets
    Interaction phenomena between atmospheric layers in planetary atmospheres give rise to highly complex exchanges influencing thermal structure, composition and dynamics. In particular, the question of hydrodynamic escape in exoplanet atmospheres is a key issue for quantifying the mass loss in these atmospheres. Short-period exoplanets subject to
