Blind and robust estimation of adaptive optics point spread function and diffuse halo with sharp-edged objects
Anthony Berdeu
Context . Initially designed to detect and characterise exoplanets, extreme adaptive optics (AO) systems open a new window onto the Solar System by resolving its small bodies. None…
Estimation of the lateral mis-registrations of the GRAVITY + adaptive optics system
Anthony Berdeu, H. Bonnet, J. -B. Le Bouquin +16
Context. The GRAVITY+ upgrade implies a complete renewal of its adaptive optics (AO) systems. Its complex design, featuring moving components between the deformable mirrors and the…
A dynamical measure of the black hole mass in a quasar 11 billion years ago
R. Abuter, F. Allouche, A. Amorim +124
Tight relationships exist in the local universe between the central stellar properties of galaxies and the mass of their supermassive black hole. These suggest galaxies and black h…
Inverse problem approach in Extreme Adaptive Optics: analytical model of the fitting error and lowering of the aliasing
Anthony Berdeu, Michel Tallon, Éric Thiébaut +5
We present the results obtained with an end-to-end simulator of an Extreme Adaptive Optics (XAO) system control loop. It is used to predict its on-sky performances and to optimise…
First observation of a quadruple asteroid -- Detection of a third moon around (130) Elektra with SPHERE/IFS
Anthony Berdeu, Maud Langlois, Frédéric Vachier
Aims. We aim to increase the contrast limits to detect new satellites orbiting known asteroids. We use cutting-edge data reduction techniques and data processing algorithms that ar…
