Academy 3 highlight

MATISSE is a unique Space observation instrument on the international scene that will provide unprecedented high-resolution data on Stars and Galactic Nuclei allowing a huge step forward in our understanding of the Universe

The project

After 15 years of work, our group has successfully built a unique space observation instrument: MATISSE (Multi-AperTure mid-Infrared SpectroScopic Experiment). MATISSE combines the beams of four of the telescopes of the “Very Large Telescope Instrument” (VLTI) of the European Southern Observatory (ESO), one of the most prestigious optical observatories in the world (Chile). It operates in the L, M and N emission bands, thus from 3 to 13 microns of wavelength, with spectral resolutions ranging from 30 to 4500, and provides polychromatic images. Altogether these make MATISSE a unique instrument in the world with unprecedented spectroscopic capabilities and extended spectral coverage. These specifications allow MATISSE to observe and characterize simultaneously both the spatial distribution and the chemical characteristics (composition, grain size, crystallinity, etc.) of the warm dust and gas material that surround many astrophysical sources such as young stars and active Galactic Nuclei. More, MATISSE allows us to explore for the first time the closest environments of the stars, less than 10 Astronomical Units wide (1 AU = the Sun-Earth distance), and to perform this exploration at the currently highest possible resolution (a fraction of an AU).

MATISSE has been installed in the Atacama Desert in Chile. It started to operate in April 2019. The Academy 3 support allowed us to conduct some of the first observing sessions, and to lead training sessions for a few French observers including students.

MATISSE is now ready to observe the Universe. Therefore, over the next decade, MATISSE will provide unprecedented observations addressing many critical scientific questions such as the structure of Active Galactic Nuclei, the origin of dust in our Universe, the imaging of planet-forming regions around solar system analogs, etc. MATISSE is thus on its way to generate new important data and science that will make a large step forward in our understanding of the Universe.

The +

MATISSE is a unique worldwide instrumentation achievement. Its construction relied on a large multidisciplinary and international effort. It is currently the only space observation instrument operating in the mid-infrared, while combining the observation capacity of 4 telescopes. This makes it the most accurate observation instrument at the present moment. It is open to the entire scientific community.

What’s next?

More than 120 international observing proposals have already been submitted through the ESO calls from September 2018 to April 2019, to use MATISSE to observe different parts of the Universe. Tens of PhD students will be involved in these projects. Breakthrough scientific results are thus expected in the next decades thanks to MATISSE.

Project valorization

In 2017 the project was awarded a ‘Trophée de l’Innovation du Conseil départemental des Alpes Maritimes’.

For public access, the MATISSE project is advertised in a journey diary: https://www-matisse.oca.eu/fr/accueil-matisse

During the development phase of the project, most of the presentations, listed below, have been given at specialized conferences (type SPIE) dedicated to astronomical instruments. The first astrophysical observations and results will be published in 2020.
