| Abstract: |
In this work we present the science portal that is being developed
to be used for the Dark Energy Survey (DES). It is a web-based tool
that integrates several tools to access data and advanced science
products, monitor the progress of the survey and data reduction, a
broad range of science algorithms in a user-friendly interface.
Here we focus on the capabilities of the Science Portal to host
tools that generate and analyze simulations of the stellar population
in the Milky Way (MW). This tool (AddStar) was employed in the recent
paper by Rossetto et al. (2011) where the expected
resolved stellar sample of DES was simulated. This simulation led to forecasts
on how DES will be able to explore the MW structure and composition.
In this work we also discuss the possible application to other
large area surveys to make similar predictions.
AddStar in conjunction with other scientific tools in the Science
Portal can add artificial objects such as a spheroidal galaxy with a complex SFH
or a globular cluster with an associated tidal tail. This set of
tools creates a simulated sky with realistic conditions
enabling the user to make accurate predictions for satellite galaxies discovery efficiency. |
