A comparison of formation models at high redshift
Alexander Schäbe, Emilio Romano-Díaz, Cristiano Porciani +2
Modelling the molecular gas that is routinely detected through CO observations of high-redshift galaxies constitutes a major challenge for ab initio simulations of galaxy formation…
Evolution of Galaxy Shapes from Prolate to Oblate through Compaction Events
Matteo Tomassetti, Avishai Dekel, Nir Mandelker +6
We study the evolution of global shapes of galaxies using cosmological simulations. The shapes refer to the components of dark matter (DM), stars and gas at the stellar half-mass r…
Atomic carbon as a powerful tracer of molecular gas in the high-redshift Universe: perspectives for ALMA
Matteo Tomassetti, Cristiano Porciani, Emilio Romano-Diaz +2
We use a high-resolution hydrodynamic simulation that tracks the non-equilibrium abundance of molecular hydrogen within a massive high-redshift galaxy to produce mock Atacama Large…
Simulating the H2 content of high-redshift galaxies
Matteo Tomassetti, Cristiano Porciani, Emilio Romano-Diaz +1
We introduce a sub-grid model for the non-equilibrium abundance of molecular hydrogen in cosmological simulations of galaxy formation. We improve upon previous work by accounting f…
Estimating gas accretion in disc galaxies using the Kennicutt-Schmidt law
Filippo Fraternali, Matteo Tomassetti
We show how the existence of a relation between the star formation rate and the gas density, i.e. the Kennicutt-Schmidt law, implies a continuous accretion of fresh gas from the en…
