Galacticus is a semi-analytic model of galaxy formation written and maintained by Andrew Benson at The Carnegie Observatories.
Galacticus solves the equations that govern the formation and evolution of galaxies within a hierarchically assembling network of dark matter halos as occurs in cold dark matter dominated universes. It is designed for modularity and flexibility to allow for easy extension and adaptation.
GALFORM is the semi-analytical galaxy formation code developed at the ICC in Durham. The GALFORM model takes into account the main physical processes that shape the formation and evolution of galaxies (Cole et al. 2000). These are the collapse and merging of DM halos, the shock-heating and radiative cooling of gas inside DM halos, leading to the formation of galactic disks, quiescent star formation (SF) in galaxy disks, feedback from supernovae (SNe), from AGN (Bower et al 2006) and from photo-ionization of the IGM, chemical enrichment of stars and gas, and galaxy mergers driven by dynamical friction within common DM halos, which can trigger bursts of SF and lead to the formation of spheroids.
The Munich galaxy formation model includes physical prescriptions for processes such as gas cooling, star foramtion, supernova feedback, formation black hole growth and AGN feedback that have been gradually developed over the years. Recent improvements include a more efficient implementation of supernova feedback, a better treatment of the interactions between satellite and central galaxies before mergers and a more realistic tracking of the angular momentum, as material is transferred between different components.
PHOX is a virtual X-ray observatory designed to obtain synthetic observations from hydro-numerical simulations. It is split into 3, independent units, where (1) the emission associated to the gaseous component from the hydrodynamical simulation is calculated, (2) the geometry of the forseen observation and (3) the detailed instrument properties are taken into account.
These are services that allow the user to submit jobs to a batch queue. The jobs will run the listed applications. These applications will be configured using input parameters that can be set on a simple web form. The job's progress can be tracked and the results can be downloaded. Old jobs can also be revisited.
Database Query Services +
The Millennium-TAP web service provides access to the Millennium simulation database.
The service implements the IVOA TAP protocol and so supports "query batch jobs".
These are services (currently one) that allow the registered users to submit batch query jobs to the backend database. As for the JobRunner services the progress of the jobs can be tracked. This queueing support distinguishes these services from the original database query services such as MyMillennium.
SeSAM and Smac are old style jobrunner services originally developed for the German Astrophysical Observatory (GAVO). These require a special account. Contact us if you are interested in these.
Other Services +
provides a single web frontend for/to a whole number of JobRunner services (Applications + Databases).
My-Millennium provides access to the Millennium simulation database,
plus it provides an own database space (a schema) for the user.

This is a set of services that are custom built for specific tasks, i.e. are not the standardized JobRunner or batch query services. Click the >> symbol next to each link to see a description.
