Some detection tests for low complexity data models and unknown background distribution
D. Mary, S. Bourguignon, E. Roquain +2
We consider several detection situations where, under the alternative hypothesis, the signal admits a low complexity model and, under both the null and the alternative hypotheses,…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
Angular differential kernel phases
Romain Laugier, Frantz Martinache, Nick Cvetojevic +7
To reach its optimal performance, Fizeau interferometry requires that we work to resolve instrumental biases through calibration. One common technique used in high contrast imaging…
Kernel-phase analysis: aperture modeling prescriptions that minimize calibration errors
Frantz Martinache, Alban Ceau, Romain Laugier +5
Kernel-phase is a data analysis method based on a generalization of the notion of closure-phase invented in the context of interferometry, but that applies to well corrected diffra…
3D magneto-hydrodynamical simulations of stellar convective noise for improved exoplanet detection. I. Case of regularly sampled radial velocity observations
S. Sulis, D. Mary, L. Bigot
Convective motions at the stellar surface generate a stochastic colored noise source in the radial velocity (RV) data. This noise impedes the detection of small exoplanets. Moreove…
ORIGIN: Blind detection of faint emission line galaxies in MUSE datacubes
David Mary, Roland Bacon, Simon Conseil +2
One of the major science cases of the MUSE integral field spectrograph is the detection of Lyman-alpha emitters at high redshifts. The on-going and planned deep fields observations…
