The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomers will be correspondingly large and complex, requiring the application

Forming first-ranked early-type galaxies through hierarchical dissipationless merging

Autor: IDILICO Collaboration, Solanes, J. M., Perea, J. D., Darriba, L., García-Gómez, C., Bosma, A., Athanassoula, E.

We have developed a computationally competitive N-body model of a previrialized aggregation of galaxies in a flat LambdaCDM universe to assess the role of the multiple mergers that take place during the formation stage of such systems in the configur

A comparison of different indicators of chaos based on the deviation vectors. Application to symplectic mappings

Autor: Maffione, N. P., Darriba, L. A., Cincotta, P. M., Giordano, C. M.

The aim of this research work is to compare the reliability of several variational indicators of chaos on mappings. The Lyapunov Indicator (LI); the Mean Exponential Growth factor of Nearby Orbits (MEGNO); the Smaller Alignment Index (SALI); the Fast
