In the context of the I2C consortium (Intensity Interferometry at Calern), the post-doctoral researcher will participate to the experimental development and the characterization of the instruments (at the Institut de Physique de Nice), to astronomical observations (at the Calern observatory and possibly other observatories), and at the interpretation of results in collaboration with astrophysicists of the Lagrange laboratory (Observatoire de la Côte d'Azur).
- Instrumental development: The goal is to improve the sensitivity of the instrument y several means (new detectors, tip-tilt, etc.)
- Astronomical observations: characterization of Be stars, experiment with 3 telescopes, polarization-resolved measurements...
- Technical skills: instrumental optics, telescopes, photon detectors, counting electronics, data analysis.
- Basic knowledge of stellar physics.
- Team work.
- Writing of scientific articles.
The collaborative project I2C deals with the revival of the so-called "Intensity interferometry" technique, pioneered by Hanbury Brown and Twiss in the 1950s and abandoned in the 1970s. There is nowadays a renewed interest for this technique, with two complementary approaches: the use of Cherenkov telescopes (the VERITAS and MAGIC collaborations, the CTA in the future) or optical telescopes (Nice, Asiago, ...). Our consortium is currently leader on the optical approach with first success obtained in 2017/2018.
The goal is now to develop further our instrument and demonstrate its usefulness for measurements of interest for stellar astrophysics.
The post-doctoral researcher will join the "cold atom" team of Institut de Physique de Nice but will actually work within a larger consortium involving astrophysicists of the Lagrange laboratory and collaborators from the Géoazur laboratory (both with Observatoire de la Côte d'Azur). A part of the work will be on the Calern plateau.
Constraints and risks
- There will be night observations.
- Mission to other observatories are also expected.
- Having a car is recommended for going to Calern.
