The Turbulent Support (TS) and Global Hierarchical Collapse (GHC) models for molecular clouds compared. Differences, convergence, and myths
Enrique Vázquez-Semadeni, Aina Palau, Gilberto C. Gómez +8
We provide a detailed comparison between the ``turbulent support'' (TS) and ``global hierarchical collapse'' (GHC) models for molecular clouds and star formation, their respective…
The effect of photoionising feedback on the shaping of hierarchically-forming stellar clusters
Alejandro González-Samaniego, Enrique Vazquez-Semadeni
We use two hydrodynamical simulations (with and without photoionising feedback) of the self-consistent evolution of molecular clouds (MCs) undergoing global hierarchical collapse (…
Optical Integral Field Spectroscopy observations applied to simulated galaxies: Testing the fossil record method
Héctor J. Ibarra-Medel, Vladimir Avila-Reese, Sebastián F. Sánchez +2
By means of post-processed cosmological Hydrodynamics simulations we explore the ability of the fossil record method to recover the stellar mass, age gradients, and global/radial s…
The global and radial stellar mass assembly of Milky Way-sized galaxies
V. Avila-Reese, A. González-Samaniego, P. Colín +2
We study the global and radial stellar mass assembly of eight zoomed-in MW-sized galaxies produced in Hydrodynamics cosmological simulations. The disk-dominated galaxies (4) show a…
SIDM on FIRE: Hydrodynamical Self-Interacting Dark Matter simulations of low-mass dwarf galaxies
Victor H. Robles, James S. Bullock, Oliver D. Elbert +7
We compare a suite of four simulated dwarf galaxies formed in 10 haloes of collisionless Cold Dark Matter (CDM) with galaxies simulated in the same haloes with an…
Dwarf Galaxy Mass Estimators vs. Cosmological Simulations
Alejandro Gonzalez-Samaniego, James S. Bullock, Michael Boylan-Kolchin +5
We use a suite of high-resolution cosmological dwarf galaxy simulations to test the accuracy of commonly-used mass estimators from Walker et al.(2009) and Wolf et al.(2010), both o…
Hierarchical Cluster Assembly in Globally Collapsing Clouds
Enrique Vazquez-Semadeni, Alejandro Gonzalez-Samaniego, Pedro Colin
We discuss the mechanism of cluster formation in a numerical simulation of a molecular cloud (MC) undergoing global hierarchical collapse (GHC). The global nature of the collapse i…
Cluster Assembly in Hierarchically Collapsing Clouds
Enrique Vazquez-Semadeni, Alejandro Gonzalez-Samaniego, Manuel Zamora-Aviles +1
We discuss the mechanism of cluster formation in hierarchically collapsing molecular clouds. Recent evidence, both observational and numerical, suggests that molecular clouds (MCs)…
The baryonic mass assembly of low-mass halos in a Lambda-CDM Universe
Maria E. De Rossi, Vladimir Avila-Reese, Patricia B. Tissera +2
We analyse the dark, gas, and stellar mass assembly histories of low-mass halos (Mvir ~ 10^10.3 - 10^12.3 M_sun) identified at redshift z = 0 in cosmological numerical simulations.…
Downsizing of galaxies vs upsizing of dark-halos in a Lambda-CDM cosmology
Maria E. De Rossi, Vladimir Avila-Reese, Alejandro Gonzalez-Samaniego +1
The mass assembly of a whole population of sub-Milky Way galaxies is studied by means of hydrodynamical simulations within the -CDM cosmology. Our results show that while dark h…
The specific star formation rate and stellar mass fraction of low-mass central galaxies in cosmological simulations
V. Avila-Reese, P. Colín, A. González-Samaniego +4
(Abridged) By means of high-resolution cosmological simulations in the context of the LCDM scenario, the specific star formation rate (SSFR=SFR/Ms, Ms is the stellar mass)--Ms and…
