The POLARIX project on deformable lenses and the C dome has just been accepted for funding by a European organization (ACTPHAST4R). This project, partly led by Lyu Abe and Marcel Carbillet on the Lagrange side, in collaboration with the Italian colleagues of the CNR of Padova, aims at carrying out the improvement and the qualification of deformable lenses under low temperature conditions, and to carry out an operational prototype for an instrument compatible with the polar conditions (at a stbilized temperature as low as possible)
The MPO team is on Summer break!
Two workshops in the French week of astrophysics (June 7-11, 2021) were successfully chaired by some of our team members: (i) optical interferometry (led by Frantz Martinache for the CS ASHRA) and (ii) astrophotnics (led by Nick Cvetojevic).
Starting this month, David Mary will join us in the team. Welcome David!
On the 24th, the TAS PhD students' day was held online and two of our MPO PhD young researchers (Peter Chingaipe, Raphaël Pourcelot) presented their research work with brilliance!
Our team leader has officially been promoted as a Full Professor, congratulations Marcel!
The MPO team wishes you all a happy new year 2021!
A new paper from Olivier Lai has recently been accepted for publication in MNRAS: DO-CRIME: Dynamic On-sky Covariance Random Interaction Matrix Evaluation, a novel method for calibrating adaptive optics systems
Several MPO team members have recently contributed to the organization of the "Wavefront sensing in the VLT/ELT era V/ AO workshop week II" online workshop, contributing to the sharing of knowledge and exchances within our scientific community around the high-angular resolution topic in the period of pandemic.
ANR I2C: Intensity Interferometry at Calern - In a collaboration with the Institut de Physique de Nice (INPHYNI) Laboratoire Géoazur and the support of UMS Galilée, Laboratoire Lagrange contributes the the I2C project, supported by an ANR grant. After technical (Guerin et al, 2017) and scientific (Rivet et al 2020) demonstrations, this ANR funding will allow us to improve the sensitivity and increase the baselines at the Calern Observatory, to prepare for deployment at large observatories (such as the VLTI-AT and MaunaKea).
Eric Lagadec & Mamadou N'Diaye have participated to the observing run of the stellar occultation by the Polymele asteroid from Senegal. This run led by the Senegalse association for the promotion of Astronomy (ASPA) in collaboration with IRD, CNRS, OCA, UCA, Paris Observatory-PSL and Paris-Saclay University, has been performed in the framwork of the forthcoming NASA Lucy mission, which launch is expected in October 2021. See OCA press release in French: communiqué.
Romain Laugier has defended his PhD thesis entitled "Robust kernel for high contrast detections at small angular separations". Kudos to Romain!
We are delighted to welcome a new postdoc, James Leftley, who will work in collaboration with Romain Petrov on the study of AGNs with the VLTI and in particular MATISSE. Welcome James!
The website on the prediction of atmopheric turbulence and meteorological parameters is now operational at the following link https://cats.oca.eu. This website includes two services: the first one dedicated to the Calern site with a prediction with 24h in advance, the other one to the prediction on request for any site elsewhere by providing its coordinates.
With the come back at the University comes the MAUCA master in which several members of our team are involved in the formation of students (METEOR CSO, Patrice Martinez, METEOR étoiles AGB/MATISSE, Pierre Cruzalebes).
Most of our team members are on vacation. See you in September for the news of our team!
This month, Marcel Carbillet, Eric Aristidi and Eric Cotallorda will visit Ariane group in the context of the PhD of Eric C.
From 8 to 12, we will be pleased to receive Ewan Douglas (U of Arizona) and Yinzi Xin (MIT) in the framework of a collaboration MIT-France with Mamadou N'Diaye.
This month, we are pleased to receive Eric Cottalorda as a Ph.D student with CIFRE fundings with Ariane Group on a topic entitled "post-adaptive optics imaging with short integration time" under the supervision of Marcel Carbillet and Eric Aristidi. Welcome to Eric! Lagrange will receive the Ariane Group on the 27th.
From 14 to 18, Jens Kammerer, from the Australian National University, will be visiting us in the framework of his Ph.D thesis under the supervision of Mike Ireland et Frantz Martinache.
Our team had recently the pleasure to receive several collaborators with presentation of their works during MPO science coffees: M. Quintavalla and S. Bonora from CNR at Padova on adaptive lenses and Alexis Carlotti from IPAG at Grenoble on the direct imaging of exoplanets and high-spectral resolution in view of the ELTs.
On 4th, Frantz Martinache brillantly defended his Habilitation thesis (HDR in French). His research works are entitled "Pushing the limits of the diffraction further for high angular resolution astronomy". Congrats to Frantz!
This month, we are glad to welcome Mr. Alohotsy Jean-Pierre Rafalimanana as a new Ph.D student. He will work on the following topic: Prediction of the atmospheric turbulence for the optimization of the astronomical observation site and opticxal links in free space, under the supervision of Aziz Ziad and Eric Aristidi. Welcome Alohotsy!
