Economies of Scale and Merger Efficiencies: Empirical Evidence from the Chilean Pension Funds Market
(Universidad Alberto Hurtado. Facultad de Economía y Negocios, 2015)
'Fundamental Plane'-like relations from collisionless stellar dynamics: a comparison of mergers and collapses
(Blackwell Publishing LtdOxfordInglaterra, 2003)
Dissipationless collapse of spherical protogalaxies and the fundamental plane
(E D P SciencesLes Ulis CedexaFrança, 2002)
Direct formation of supermassive black holes via multi-scale gas inflows in galaxy mergers
(NATURE PUBLISHING GROUP, 2010-08-26)
Observations of distant quasars indicate that supermassive black holes of billions of solar masses already existed less than a billion years after the Big Bang1. Models in which the ‘seeds’ of such black holes form by ...
Analysis of Star Formation in Galaxy-like Objects
(IOP Publishing, 2000-12)
Using cosmological hydrodynamical simulations, we investigate the effects of hierarchical aggregation on the triggering of star formation in galactic-like objects. We include a simple star formation model to transform the ...
Fragmentation of neutron star matter
(American Physical Society, 2017-05)
Background: Neutron stars are astronomical systems with nucleons subjected to extreme conditions. Due to the longer range Coulomb repulsion between protons, the system has structural inhomogeneities. Several interactions ...
Morphology of galaxies with quiescent recent assembly history in a Λ-CDM universe
(EDP Sciences, 2014-07)
Context. The standard disc formation scenario postulates that the disc forms as the gas cools and flows into the centre of the dark matter halo, conserving the specific angular momentum. Major mergers have been shown to ...
Fingerprints of the hierarchical building-up of the structure on the gas kinematics of galaxies
(EDP Sciences, 2012-10)
Context. Recent observational and theoretical works have suggested that the Tully-Fisher relation might be generalised to include dispersion-dominated systems by combining the rotation and dispersion velocity in the ...
Modeling the color magnitude relation for galaxy clusters
(University Of Chicago Press, 2010-10)
We investigate the origin of the colour-magnitude relation (CMR) observed in cluster galaxies by using a combination of a cosmological N-body simulation of a cluster of galaxies and a semi-analytic model of galaxy ...
nIFTy cosmology: comparison of galaxy formation models
(Oxford University Press, 2015-06)
We present a comparison of 14 galaxy formation models: 12 different semi-analytical models and 2 halo-occupation distribution models for galaxy formation based upon the same cosmological simulation and merger tree information ...
