Relation between halo spin and cosmic web filaments at z=3
Roberto E. Gonzalez, Joaquin Prieto, Nelson Padilla +1
We investigate the spin evolution of dark matter haloes and their dependence on the number of connected filaments from the cosmic web at high redshift (spin-filament relation herea…
The origin of spin in galaxies: clues from simulations of atomic cooling halos
Joaquin Prieto, Raul Jimenez, Zoltán Haiman +1
In order to elucidate the origin of spin in both dark matter and baryons in galaxies, we have performed hydrodynamical simulations from cosmological initial conditions. We study at…
Over-cooled haloes at z > 10: a route to form low-mass first stars
Joaquin Prieto, Raul Jimenez, Licia Verde
It has been shown by Shchekinov & Vasiliev2006 (SV06) that HD molecules can be an important cooling agent in high redshift z >10 haloes if they undergo mergers under specific condi…
Gas infall into atomic cooling haloes: on the formation of protogalactic disks and supermassive black holes at z > 10
Joaquin Prieto, Raul Jimenez, Zoltan Haiman
We have performed cosmo-hydro simulations using the RAMSES code to study atomic cooling (ACHs) haloes at z=10 with masses 5E7Msun<~M<~2E9Msun. We assume primordial gas and H2-cooli…
Dark matter merging induced turbulence as an efficient engine for gas cooling
Joaquin Prieto, Raul Jimenez, Jose Martí
We have performed a cosmological numerical simulation of primordial baryonic gas collapsing onto a M dark matter (DM) halo. We show that the large scale bary…
Pop. III stars from turbulent fragmentation at redshift ~ 11
Joaquin Prieto, Paolo Padoan, Raul Jimenez +1
We report results from a cosmological simulation with non-equilibrium chemistry of 21 species, including H2, HD, and LiH molecular cooling. Starting from cosmological initial condi…
