Diffusion Models for Polarimetric Reconstruction of Circumstellar Environments in Correlated Speckle Noise

Quentin Villegas, Laurence Denneulin, Simon Prunet +3

High-contrast polarimetric imaging of circumstellar disks is severely limited by stellar leakage and speckle noise. Building upon the RHAPSODIE framework for polarimetric inverse p…

Diffusion models for polarimetric reconstruction of circumstellar environments

Quentin Villegas, Laurence Denneulin, Simon Prunet +5

In this paper, we propose an approach combining diffusion models and inverse problems for the reconstruction of circumstellar disk images. Our method builds upon the Rhapsodie fram…

RHAPSODIE: Reconstruction of High-contrAst Polarized SOurces and Deconvolution for cIrcumstellar Environments

Laurence Denneulin, Maud Langlois, Éric Thiébaut +1

Polarimetric imaging is one of the most effective techniques for high-contrast imaging and characterization of circumstellar environments. These environments can be characterized t…

Primal-dual splitting scheme with backtracking for handling with epigraphic constraint and sparse analysis regularization

Laurence Denneulin, Nelly Pustelnik, Maud Langlois +2

The convergence of many proximal algorithms involving a gradient descent relies on its Lipschitz constant. To avoid computing it, backtracking rules can be used. While such a rule…

First scattered light detection of a nearly edge-on transition disk around the T Tauri star RY Lup

M. Langlois, A. Pohl, A. -M. Lagrange +41

Transition disks are considered sites of ongoing planet formation, and their dust and gas distributions could be signposts of embedded planets. The transition disk around the T Tau…
