A possible mechanism to form low mass objects at low redshifts
(SpringerDordrechtHolanda, 2005)
Structural evolution of the 40 km wide Araguainha impact structure, central Brazil
(Wiley-blackwellHobokenEUA, 2008)
Formation of wakes by chiral conducting cosmic strings
(World Scientific Publ Co Pte Ltd, 2004-10-20)
Chiral cosmic strings are naturally produced at the end of D-term inflation and they present very interesting cosmological consequences. In this work, we investigate the formation and evolution of wakes by a chiral string. ...
Formation history, structure and dynamics of discs and spheroids in simulated Milky Way mass galaxies
(Oxford University Press, 2011-10)
We study the stellar discs and spheroids in eight simulations of galaxy formation within Milky Way mass haloes in a cold dark matter cosmology. The first paper in this series concentrated on disc properties. Here we extend ...
Aspectos microestruturais e texturais dos metassedimentos da formacao eleuterio
(1990-12-01)
This work describes the primary and tectonic-metamorphic structures of the Eleuterio Formation, cropping 1 km NW of the village of Eleuterio, State of Sao Paulo. The structural feature have been studied chiefly in low grade ...
The interstellar medium and star formation in local galaxies: variations of the star formation law in simulations
(The American Astronomical Society., 2014)
We use the adaptive mesh refinement code Enzo to model the interstellar medium (ISM) in isolated local disk
galaxies. The simulation includes a treatment for star formation and stellar feedback. We get a highly ...
Structure formation in the presence of dark energy perturbations
(Iop Publishing Ltd, 2007-11-01)
We study non-linear structure formation in the presence of dark energy. The influence of dark energy on the growth of large-scale cosmological structures is exerted both through its background effect on the expansion rate, ...
Stellar structures, molecular gas, and star formation across the PHANGS sample of nearby galaxies
(EDP, 2021)
We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct morphological masks of sub-galactic environments based on Spitzer 3.6 mu m images. At the simplest level, we distinguish five environments: ...
Numerical model to predict the position, amount and size of microporosity formation in Al-Cu alloys by dissolved gas and solidification shrinkage
(Elsevier Science SaLausanneSuíça, 2004)
Terrestrial planet formation constrained by mars and the structure of the asteroid belt
(2015-01-01)
Reproducing the large Earth/Mars mass ratio requires a strong mass depletion in solids within the protoplanetary disc between 1 and 3 au. The Grand Tack model invokes a specific migration history of the giant planets to ...
