Introduction to Regularization and Learning Methods for Inverse Problems
Danielle Bednarski, Tim Roith
These lecture notes evolve around mathematical concepts arising in inverse problems. We start by introducing inverse problems through examples such as differentiation, deconvolutio…
Inverse Scale Space Iterations for Non-Convex Variational Problems: The Continuous and Discrete Case
Danielle Bednarski, Jan Lellmann
Non-linear filtering approaches allow to obtain decompositions of images with respect to a non-classical notion of scale, induced by the choice of a convex, absolutely one-homogene…
Inverse Scale Space Iterations for Non-Convex Variational Problems Using Functional Lifting
Danielle Bednarski, Jan Lellmann
Non-linear filtering approaches allow to obtain decompositions of images with respect to a non-classical notion of scale. The associated inverse scale space flow can be obtained us…
On the Connection between Dynamical Optimal Transport and Functional Lifting
Thomas Vogt, Roland Haase, Danielle Bednarski +1
Functional lifting methods provide a tool for approximating solutions of difficult non-convex problems by embedding them into a larger space. In this work, we investigate a mathema…
Visible and near-infrared spectro-interferometric analysis of the edge-on Be star Aquarii
E. S. G. de Almeida, A. Meilland, A. Domiciano de Souza +11
We present a detailed visible and near-IR spectro-interferometric analysis of the Be-shell star Aquarii from quasi-contemporaneous CHARA/VEGA and VLTI/AMBER observations. We me…
The Complex Circumstellar and Circumbinary Environment of V356 Sgr
Jamie R. Lomax, Andrew G. Fullard, Michael A. Malatesta +13
We analyze 45 spectropolarimetric observations of the eclipsing, interacting binary star V356 Sgr, obtained over a period of 21 years, to characterize the geometry of the system's…
Investigating the Circumstellar Disk of the Be Shell Star 48 Librae
J. Silaj, C. E. Jones, A. C. Carciofi +6
A global disk oscillation implemented in the viscous decretion disk (VDD) model has been used to reproduce most of the observed properties of the well known Be star Tau. 48 Lib…
Dynamical Evolution of Viscous Disks around Be Stars. II : polarimetry
Xavier Haubois, Bruno C. Mota, Alex C. Carciofi +4
Be stars exhibit variability for a great number of observables. Putting the pieces together of the disk dynamics is not an easy task and requires arduous modeling before achieving…
Monitoring the Polarimetric Variability of δ Scorpii
Daniel Bednarski, Alex Cavaliéri Carciofi
The Be star δ Scorpii is an interesting binary system, whose primary companion created a circumstellar disk after the periastron passage of the secondary in 2000, being since then…
