Morphology-aware periodicity searches in Fermi-LAT blazars

Aaron A. Maldonado, Alberto Domínguez, Adithiya Dinesh +4

Standard periodicity searches in active galactic nuclei assume sinusoidal modulation, whereas gamma-ray blazar emission often features asymmetric flares and localized bursts. We in…

The Quasar Main Sequence of Super-Eddington NLSy1 Galaxies

Alberto Domínguez, Suvendu Rakshit, Vaidehi S. Paliya +2

The quasar main sequence, or Eigenvector 1 (EV1), describes the optical diversity of active galactic nuclei (AGN), with Narrow-Line Seyfert 1 (NLSy1) galaxies anchoring the high-ac…

Damped nonlinear Ginzburg-Landau equation with saturation. Part I. Existence of solutions on general domains

Pascal Bégout, Jesús Ildefonso Díaz

We study the complex Ginzburg-Landau equation posed on possibly unbounded domains, including some singular and saturated nonlinear damping terms. This model interpolates between th…

Identifiability and Observability Analysis for Epidemiological Models: Insights on the SIRS Model

Alicja B Kubik, Benjamin Ivorra, Alain Rapaport +1

The problems of observability and identifiability have been of great interest as previous steps to estimating parameters and initial conditions of dynamical systems to which some k…

Dense Crowd Dynamics and Pedestrian Trajectories: A Multiscale Field Study at the Fête des Lumières in Lyon

Oscar Dufour, Huu-Tu Dang, Jakob Cordes +5

We present one of the first comprehensive field datasets capturing dense pedestrian dynamics across multiple scales, ranging from macroscopic crowd flows over distances of several…

Strong stabilization of damped nonlinear Schr{ö}dinger equation with saturation on unbounded domains

Pascal Bégout, Jesús Ildefonso Díaz

We consider the damped nonlinear Schr\''{o}dinger equation with saturation: i.e., the complex evolution equation contains in its left hand side, besides the potential term …
