scientific rationale

VLTI schools of interferometry have been organized roughly every two years since the opening of ESO Very Large Telescope Interferometer in 2002. They have helped to train hundreds of astrophysicists in using interferometry and the instruments at VLTI and other facilities for their research.

The aim of  these VLTI schools is to offer Ph.D. students, post-doctoral and permanent researchers an introduction to the technique of long-baseline optical/infrared interferometry, an overview of the current generation of instruments, and lectures and practice sessions in data reduction, modelling and image reconstruction. Seminars and reviews on astrophysical results in various fields ranging from stellar physics to planetology and extra-galactic science are also given. While remaining as comprehensive as possible, each school also focused on a subject such as a new instrument, a problematic in interferometry, or a field of astrophysics.

The 10th VLTI school will focus on the latest VLTI instrument : MATISSE, the new four-beam combiner operating in the mid-infrared, from 2.8 to 13 microns, build by a international consortium led by the Observatoire de la Côte d'Azur and open to the community since April 2019. It will also set emphasis on one of MATISSE driving astrophysical program: planetology.


The school was supposed to take place in 2020 but was delayed by almost a year due to the covid-19 crisis. It will finally be held in at heart of Côte d'Azur

in Sophia-Antipolis, France

on June 6-12, 2021.
