Towards simulating star formation in the interstellar medium by Slyz, A, Devriendt, J, Bryan, G, Silk, J

“…As a first step to a more complete understanding of the local physical processes which determine star formation rates (SFRs) in the interstellar medium (ISM), we have performed controlled numerical experiments consisting of hydrodynamical simulations of a kilo-parsec scale, periodic, highly supersonic and "turbulent" three-dimensional flow. …”

Simulating star formation and feedback on a galaxy scale by Slyz, A

“…Insufficient computational power and numerous poorly understood physical processes, force simulations to adopt sub-grid models of the interstellar medium. These may crucially bias results. We advocate for smaller (similar to kiloparsec) scale simulations of the interstellar medium to guide the development of sub-grid models in larger simulations. …”

“…While multiple LyC escape fraction (<em>f</em>_esc) indicators have been proposed to trace favourable conditions for LyC leakage from the interstellar medium of low-redshift &lsquo;analogue&rsquo; galaxies, it remains unclear whether these are applicable at high redshifts where LyC emission cannot be directly observed. …”

Galactic star formation in parsec-scale resolution simulations by Powell, L, Bournaud, F, Chapon, D, Devriendt, J, Slyz, A, Teyssier, R

A detailed study of feedback from a massive star by Geen, S, Rosdahl, J, Blaizot, J, Devriendt, J, Slyz, A

“… <p>We present numerical simulations of a 15 M_⊙ star in a suite of idealized environments in order to quantify the amount of energy transmitted to the interstellar medium (ISM). We include models of stellar winds, UV photoionization and the subsequent supernova based on theoretical models and observations of stellar evolution. …”

Turbulent ambipolar diffusion: Numerical studies in two dimensions by Heitsch, F, Zweibel, E, Slyz, A, Devriendt, J

“…Under ideal MHD conditions the magnetic field strength should be correlated with density in the interstellar medium (ISM). However, observations indicate that this correlation is weak. …”

The dusty, albeit ultraviolet bright infancy of galaxies by Devriendt, J, Rimes, C, Pichon, C, Teyssier, R, Borgne, D, Aubert, D, Audit, E, Colombi, S, Courty, S, Dubois, Y, Prunet, S, Rasera, Y, Slyz, A, Tweed, D

“…This agreement is remarkably good considering our admittedly still simple modelling of the interstellar medium (ISM) physics. The luminosity functions (LF) of virtual UV luminous galaxies coincide with the existing data over the whole redshift range from 4 to 7, provided cosmological parameters are set to their currently favoured values. …”

A three-phase amplification of the cosmic magnetic field in galaxies by Martin-Alvarez, S, Devriendt, J, Slyz, A, Teyssier, R

“…Arguably the main challenge of galactic magnetism studies is to explain how the interstellar medium of galaxies reaches energetic equipartition despite the extremely weak cosmic primordial magnetic fields that are originally predicted to thread the inter-galactic medium. …”

“…While these formation channels have been studied using hydrodynamical simulations, here we study their impact on gas properties and star formation (SF) with some of the first from simulations that capture the multiphase, cloudy nature of the interstellar medium (ISM), by virtue of their high spatial resolution (and corresponding low temperature threshold). …”

Towards simulating star formation in turbulent high-z galaxies with mechanical supernova feedback by Kimm, T, Cen, R, Devriendt, J, Dubois, Y, Slyz, A

“…This is achieved by making three important changes to the classical feedback scheme: (i) the different phases of SN blast waves are modelled directly by injecting radial momentum expected at each stage, (ii) the realistic time delay of SNe is required to disperse very dense gas before a runaway collapse sets in, and (iii) a non-uniform density distribution of the interstellar medium (ISM) is taken into account below the computational grid scale for the cell in which an SN explodes. …”

Exploring spiral galaxy potentials with hydrodynamical simulations by Slyz, A, Kranz, T, Rix, H

“…More specifically, we explore the dependence of the positions and amplitudes of features in the gas flow on the temperature of the interstellar medium (assumed to behave as a one-component isothermal fluid), the non-axisymmetric disk contribution to the galactic potential, the pattern speed, Omega_p, and finally the numerical resolution of the simulation. …”
