Over the next decade, much of the effort on major astronomical facilities will be dedicated to large scale surveys on the galaxy population.
Their aim is two-fold:
understanding the origin and evolution of galaxies and their central supermassive black holes,
and clarifying the nature of dark matter, dark energy and the process that produced all cosmic structure.
The goal of the Galformod Project is to develop and provide powerful and flexible modeling tools
that can simulate the evolution of the galaxy population in all viable cosmologies
and under a wide variety of assumptions about the governing physical processes.
This shall be achieved by a major expansion of the functionality and scope of the Millennium Simulation Archive.
The Millennium-Run Observatory allows to browse and deep zoom mock images
that are the most extreme end product of the Millennium simulation post-processing pipeline.
The images are derived from lightcones built
from semi-analytic galaxy catalogs and virtual telescope images after
processing theoretical galaxies through the specs of modern surveys.
The interactive browser allows the user to obtain information about galaxies in the image
from the database containing the catalogues and light cones.
Completed in 2005, the Millennium Simulation had a dramatic impact
on the fields of cosmology structure formation and galaxy evolution.
The Millennium Run used more than 10 billion particles to trace the
evolution of the matter distribution in a cubic region of the Universe
over 2 billion light-years on a side. It kept busy the principal
supercomputer at the Max Planck Society's Supercomputing Centre in
Garching, Germany for more than a month.
In recent years the volume and dynamic range of the simulated evolution
of dark matter substructures has been dramatically increased with the
arrival of the MillenniumII and MillenniumXXL simulations. The former
increased the Millennium mass resolution 125 times, following the dark
matter halos that host the smallest galaxies observed in the local
universe (107 solar masses); the later boosted the simulated volume to
a cubic box with 3Gpc on a side, covering the full observable sky out to
z=1. Predictions for WMAP1 and WMAP7 cosmologies (either by direct
simulations or scaling methods) are now available.
By applying sophisticated modelling techniques to the 25 Tbytes of
stored output, Virgo scientists have been able to recreate evolutionary
histories both for the millions of galaxies which populate this enormous
volume and for the supermassive black holes which occasionally power
quasars at their hearts. By comparing such simulated data to large
observational surveys, one can clarify the physical processes underlying
the buildup of real galaxies and black holes. The combined resources
offer an unprecedented tool to understand the physics underlying the
formation and evolution of dark matter structures and galaxies.
All catalogs are available for download.
The TAP Service (Table Access Protocol) allows batch queries to the
Millennium simulation data, similar to the MyMillennium query interfaces.
The closer control over the execution of the SQL queries in the batch queue
has the advantage that we can allow much longer time-out limits on the queries.
The data returned can be downloaded when a query job has finished
or displayed directly in the TOPCAT table visualization tool.
The interactive MillenniumXXL browser gives access to the halo catalogues
from the XXL simulation via a point-and-click browsing interface.
Our Computing ("Job Runner") Portals allow users to conveniently run more general
science applications via the web.
Currently the focus is on semi-analytic codes like MPA's L-Galaxies, which can be run through a simple
input form that allows one to choose/enter various input parameters and allowing
certain physics to be changed for each run. The jobs will be run on a batch queue and the resulting galaxy catalogs
can be easily downloaded. More tools will be added
The Applications Dashboard provides a single point of access to (almost) all Galformod Web Services.
It allows users to run the services from a
single interface, to track progress of jobs and view and access the
results. It allows users to browse and manage the list of all
previous jobs and where applicable provide further services for
visualising or analysing the results further.
The user interface of this application is
somewhat more complex than your standard, single application
interface. This page provides detailed descriptions of the various
components and their functions.
this feature is not yet implemented. sorry for the inconvenience.
