Evidence for Hierarchical Turbulent Scaling in Nearby Star-Forming Galaxies
Luna Maria Scipio, Fernando A. N. Santos, Jay Armas
We find recurring signatures of intermittency in molecular-gas velocities from cloud to galactic scales. In 31 selected galaxies from PHANGS-ALMA, velocity-centroid exponents throu…

Hyperscaling of spatial fluctuations constrains the development of urban populations
Wout Merbis, Fernando A. N. Santos, Jay Armas +2
Urban populations exhibit fractal organization and systematic scaling regularities, yet the scaling exponents reported across cities vary substantially, challenging existing theory…

Efficient set-theoretic algorithms for computing high-order Forman-Ricci curvature on abstract simplicial complexes
Danillo Barros de Souza, Jonatas T. S. da Cunha, Fernando A. N. Santos +2
Forman-Ricci curvature (FRC) is a potent and powerful tool for analysing empirical networks, as the distribution of the curvature values can identify structural information that is…
