This paper presents the measurements of the angular differential cross sections for the forward production of He, Li, Be, B, C and N nuclei in the fragmentation process of a 400$\text{MeV/nucleon}$ $^{16}\text{O}$ beam interacting with a graphite tar

Planet-driven spirals in protoplanetary discs: limitations of the semi-analytical theory for observations

Detecting protoplanets during their formation stage is an important but elusive goal of modern astronomy. Kinematic detections via the spiral wakes in the gaseous disc are a promising avenue to achieve this goal. We aim to test the applicability to o

Bessel kernel determinants and integrable equations

Publikováno v: Annales Henri Poincar\'e, 2025

We derive differential equations for multiplicative statistics of the Bessel determinantal point process depending on two parameters. In particular, we prove that such statistics are solutions to an integrable nonlinear partial differential equation

Asteroids co-orbital motion classification based on Machine Learning

Autor: Ciacci, Giulia, Barucci, Andrea, Di Ruzza, Sara, Alessi, Elisa Maria

In this work, we explore how to classify asteroids in co-orbital motion with a given planet using Machine Learning. We consider four different kinds of motion in mean motion resonance with the planet, nominally Tadpole, Horseshoe and Quasi-satellite,

J\'anossy densities and Darboux transformations for the Stark and cylindrical KdV equations

Autor: Claeys, Tom, Glesner, Gabriel, Ruzza, Giulio, Tarricone, Sofia

Publikováno v: Communications in Mathematical Physics, 2024

We study J\'anossy densities of a randomly thinned Airy kernel determinantal point process. We prove that they can be expressed in terms of solutions to the Stark and cylindrical Korteweg-de Vries equations; these solutions are Darboux tranformations
