What does lie at the Milky Way centre? Insights from the S2 star orbit precession
C. R. Argüelles, M. F. Mestre, E. A. Becerra-Vergara +4
It has been recently demonstrated that both, a classical Schwarzschild black hole (BH), and a dense concentration of self-gravitating fermionic dark matter (DM) placed at the Galax…
The Fornax Cluster through S-PLUS
A. V. Smith Castelli, C. Mendes de Oliveira, F. Herpich +25
The Southern Photometric Local Universe Survey (S-PLUS) aims to map 9300 deg of the Southern sky using the Javalambre filter system of 12 optical bands, 5 Sloan-like…
Effects of chaos on the detectability of stellar streams
Martín Mestre, Claudio Llinares, Daniel D. Carpintero
Observations show that stellar streams originating in satellite dwarf galaxies are frequent in the Universe. While such events are predicted by theory, it is not clear how many of…
Stochastic approach to diffusion inside the chaotic layer of a resonance
Martín F. Mestre, Armando Bazzani, Pablo M. Cincotta +1
We model chaotic diffusion, in a symplectic 4D map by using the result of a theorem that was developed for stochastically perturbed integrable Hamiltonian systems. We explicitly co…
Chirikov and Nekhoroshev diffusion estimates: bridging the two sides of the river
Pablo M. Cincotta, Christos Efthymiopoulos, Claudia M. Giordano +1
We present theoretical and numerical results pointing towards a strong connection between the estimates for the diffusion rate along simple resonances in multidimensional nonlinear…
Analysis of Round Off Errors with Reversibility Test as a Dynamical Indicator
Davide Faranda, Martin Federico Mestre, Giorgio Turchetti
We compare the divergence of orbits and the reversibility error for discrete time dynamical systems. These two quantities are used to explore the behavior of the global error induc…
