Assembly of spheroid-dominated galaxies in the EAGLE simulation
(Astronomy and Astrophysics, 2019)
Context: Despite the insights gained in the last few years, our knowledge about the formation and evolution scenario for the spheroid-dominated galaxies is still incomplete. New and more powerful cosmological simulations ...
Comparing the pre-SNe feedback and environmental pressures for 6000 HII regions across 19 nearby spiral galaxies
(Oxford, 2021)
The feedback from young stars (i.e. pre-supernova) is thought to play a crucial role in molecular cloud destruction. In this paper, we assess the feedback mechanisms acting within a sample of 5810 Hii regions identified ...
On the theory of mass-loss in dwarf galaxies – I. Basic equations and the case of wave/thermal driven winds
(Oxford, 2013-06)
In this work, we present a semi-analytical model of galactic wind for dwarf galaxies where thermal and turbulent/momentum driving mechanisms are studied. The model takes into account wave and internal adiabatic heating ...
The stellar metallicity gradients in galaxy discs in a cosmological scenario
(2016)
Context. The stellar metallicity gradients of disc galaxies provide information on disc assembly, star formation processes, and chemical evolution. They also might store information on dynamical processes that could affect ...
Field spheroid-dominated galaxies in a Lambda-CDM Universe
(2018)
Context. Understanding the formation and evolution of early-type, spheroid-dominated galaxies is an open question within the context of the hierarchical clustering scenario, particularly in low-density environments. Aims. ...
Angular momentum evolution for galaxies in a Lambda-CDM scenario
(2015)
Context. Galaxy formation in the current cosmological paradigm is a very complex process in which inflows, outflows, interactions, and mergers are common events. These processes can redistribute the angular momentum content ...
The joint evolution of baryons and dark matter haloes
(Wiley Blackwell Publishing, Inc, 2010-02)
We have studied the dark matter (DM) distribution in an ≈1012 h−1 M mass halo extracted from a simulation consistent with the concordance cosmology, where the physics regulating the transformation of gas into stars was ...
Hydrodynamical simulations of Galactic fountains - II. Evolution of multiple fountains
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
The ejection of gas out of the disc in late-type galaxies is related to star formation and is mainly due to the explosion of Type II supernovae (SN II). In a previous paper, we considered the evolution of a single Galactic ...
The impact of baryons on dark matter haloes
(Oxford University Press, 2009-05)
We analyse the dark matter (DM) distribution in an ≈1012 M halo extracted from a simulation consistent with the concordance cosmology, where the physics regulating the transformation of gas into stars was allowed to change ...
