Building the Galilean moons system via pebble accretion and migration: A primordial resonant chain
(2021-06-01)
The origins of the Galilean satellites - namely Io, Europa, Ganymede, and Callisto - is not fully understood yet. Here we use N-body numerical simulations to study the formation of Galilean satellites in a gaseous ...
Cosmic queuing: galaxy satellites, building blocks and the hierarchical clustering paradigm
(2009)
We study the properties of building blocks (BBs; i.e. accreted satellites) and surviving satellites of present-day galaxies using the semi-analytic model of galaxy formation SAG (‘semi-analytic galaxies’) in the context ...
Dynamics of Built-Up Areas over The Past 30 Years According to Remote Sensing Data in the City of Valdivia, Chile
(IEEE, 2018)
The dynamics of built-up areas over the last 30 years in the city of Valdivia was analyzed according to Landsat satellite imagery data. For ETM+/Landsat-7 and OLI/Landsat-8 instrumentation systems, method of automatic ...
