Simulating the LOcal Web
SLOW is based on the same initial constrains of CLONES, and is based on initial conditions for a (500Mpc/h)^3 large region and aims to simulate the local Universe. Various resolutions levels are used to performed simulations with different level of additional physics.
  • Dark matter only simulations were performed using 768^3, 1576^3, 3072^3 and 6144^3 particles.
  • Magneto-hydodynamical, non radiative simulations but following also a cosmic ray component using 2x3072^3 gas and dark matter particles.
  • Hydrodynamical, full galaxy formation physics simulation (same as Magneticum) using 2x768^3, 2x1576^3 and 2x3072^3 gas and dark matter particles (last one only down to z = 2).

Compass



Compass aims for high resolution zoom simulations of galaxies and galaxy clusters.
With the aim to study in detail the interaction of galaxies with the ICM as well as microphysical processes like the evolution of magnetic fields, turbulence and cosmic rays within the ICM we extending the Dianoga simulations to far higher resolution. The aim is have 250 time more (Phase I) and 2500 times more (Phase II) resolution elements. This pushes simulations of massive clusters to so far never reached precision. Dark matter particle masses in the simulations will be 3.3e6 Msol/h (250x) / 3.3e5 Msol/h (2500x) and softening for dark matter and gas particles will be 0.5 kpc/h (250x), 0.2 kpc/h (2500x). The clusters will therefore be described by more than 600,000,000 particles within the virial radius and typically the simulations will resolve 100,000 galaxies within individual clusters.
With the aim to study in detail the evolution of galaxies and especially the outskirts of the galactic halo, we extending the Dianoga simulations to include groups, massive field galaxies and normal galaxies to be simulated at very high resolution. The aim is to have 250 and 2500 time more resolution (Phase I) and even explore 25000 times more resolution (Phase II). This pushes simulations of galaxies to have dark matter particle masses of 3.3e4 Msol/h (25000x). A MW like galaxy will be therefore resolved with 20,000,000 particles within the virial radius.

Magneticum Pathfinder
Magneticum Pathfinder aims to follow the formation of cosmological structures in a so far unaccomplished level of detail by performing a set of large scale and high resolution simulations, taking into account many physical processes to allow detailed comparison to a variety of multi-wavelength observational data. Using WMAP7 cosmology, the largest sets of simulations will be Box1 (L=896 Mpc/h, n=2x1526^3, m_dm=1.6e10 Msol/h) and Box2 (L=352 Mpc/h, n=2x1584^3, m_dm=8.3e8 Msol/h) and Box3 (L=128 Mpc/h, n=2x1526^3, m_dm=4.4e7 Msol/h) and various simulations with less particles. All simulations include various physical processes (thermal conduction, star-formation and chemical enrichment, growth of BHs and AGN feedback). First simulations where performed at SARA under the project MagPath. Additional simulations where performed on JUGENE within the framework of a GAUSS proposal. The next larger simulations are performed on SuperMuc within a new GAUSS proposal. The project wiki (restricted).
Dianoga
Dianoga is a set of mass limited galaxy clusters, extracted from a low- resolution dark matter (DM) simulation, which covers a box size of 1 Gpc/h and used 1024^3 particles to describe a standard WMAP-7 LCDM cosmological model. From this simulation we extracted 24 Lagrangian regions around the most massive clusters. For each of these regions, initial conditions have been re-generated by increasing mass resolution and adding high-frequency modes, while progressively degrading resolution in outer regions. For each cluster, initial conditions have been generated at two different resolutions: a low resolution (LR) version, corresponding to a mass of the DM particle in the high-resolution region of 10^9 Msun/h, and a high resolution (HR) version with 10 times smaller DM particles mass, 10^8 Msun/h.

Name explanation Dianoga.

The initial conditions where created to have a large (typical 5 R_vir) region around the objects, which is free from boundary effects. These simulations are performed for some combination of physical effects included. There are several online services available.

It has a mass resolution of 2.0e8 Msol/h for the dark matter particles, and host nearly 11 Million dark matter particles within R_vir at z=0. A run with cooling, starformation and feedback is actually running (also including chemical enrichment from SN-Ia and II, by using the Metget developement by Tornatore et al. (2004)), and a gas run with low viscosity will be started soon.

Very advanced Cluster simulations
Vader is a ultra high resolution re-simulations of some clusters from the Hutt sample. Sofar, starting with g676, the highest mass resolution reached is 1.0e7 Msol/h for the dark matter particles, corresponding to a gravitational softening of 1 kpc/h, and therefore complements Luke in the small mass end.
Name explanation Vader.
Multi Million Particle Keyproject Cluster re-simulations
Tarkin is a set of high-resolution resimulations of clusters extracted from the cosmological box simulated with the Keyproject-2003, with initial conditions realized with the ZIC technique. The simulations have been realized with the twofold aim of reaching high resolution to study numerical convergence of X-ray and optical observational properties of galaxy clusters, and to span a variety of models for star formation, chemical enrichment and feedback strength. The highest resolution runs resolve each cluster with about 2e6 DM particles within the virial radius at z=0. They are realized with the original P-Gadget2 code. A battery of simulations with lower mass resolution (by a factor 3-4) are realized by also including chemical enrichment from SN-Ia and II, by using the Metget developement by Tornatore et al. (2004). Different runs have been carried out by changing the stellar IMF and the wind velocity, as defined in the original model by Springel & Hernquist (2003). Heavely suppressed thermal conduction (1/20th Spitzer) is also included, following the method by Jubelgas et al. (2004)
Name explanation Tarkin.
Padova Dark energy Model cluster

The Simulated a box is 192 Mpc/h on a side and includes the effect of radiative cooling, cooling/heating by a uniform evolving UV background, star formation, a recipe to account for the multi-phase nature of the inter-stellar medium, where star formation takes place, feedback and metal enrichment from type-II supernova explosions and the effect of galactic winds.

Constrained Local Universe including Magnetic Fields
Coruscant is a cosmological re-simulation of the local universe based on initial conditions reconstructed from the 1.2 muJ IRAS full sky survey. This simulation is designed to represent the observed local neighborhood out to 80Mpc/h and makes it possible to identify prominent haloes from the simulations with real observed galaxy cluster. This re-simulation also includes adiabatic gas physics and the evolution of a week, seed magnetic field. Its purpose is to study the magnetic field and the propagation of cosmic rays within clusters and the local universe. Recently there have beed also re-simulations to study the distribution and evolution of magnetic fields originating from galactic outflows. The project Wiki (restricted).

Constrained Simulation for detectabiliy of WHIM in the Local Universe
Salacious is a cosmological re-simulation of the local universe based on initial conditions reconstructed from the 1.2 muJ IRAS full sky survey. This simulation is designed to represent the observed local neighborhood out to 80Mpc/h and makes it possible to identify prominent haloes from the simulations with real observed galaxy cluster. This re-simulation is similat to the Coruscant simulation, but instead of tracing the magnetic field it follows cooling, starformation, feedback and the spreading of metal in the intra cluster medium. The main goal of this simulation is to study the detectability of WHIM in local super cluster structures. Recently it was also re-simulated including the growth of BHs and the feedback by AGNs.
Name explanation Salacious.
