Submillimeter observations are a key for answering many of the big questions in modern-day astrophysics, such as how stars and planets form, how galaxies evolve, and how material cycles through stars and the interstellar medium. With the large submillimeter facilities ALMA and Herschel a new window will open to study these questions. Within the ASTRONET first joint call for proposals, "Common Tools for Future Large Submillimeter Facilities", we have been awarded funding for our program, "Adaptable Radiative Transfer Innovations for Submillimeter Telescopes (ARTIST)", to develop a next generation model suite for comprehensive multi-dimensional radiative transfer calculations of the dust and line emission, as well as their polarization, to help interpret observations with these groundbreaking facilities.

The ARTIST package consists of:

  1. An innovative radiative transfer code (LIME) using adaptive gridding that allows simulations of sources with arbitrary multi-dimensional (1D, 2D, 3D) and time-dependent structures, ensuring rapid convergence.

  2. Unique tools for modeling the polarization of the line and dust emission, information that will come with standard ALMA observations.

  3. A library of commonly used analytic/semi-analytic models as well as a comprehensive graphical user interface.

On these pages we present the ARTIST package with its individual (eventually) publicly available components. For more information about download and installation, please see the ARTIST forum where you can also subscribe to news or follow our RSS feed.

Latest news (21.02.2014): ARTIST version 1.1 is now available for download. It can be downloaded as a fully workable package on most common Linux flavors and Mac OS X (a number of dependencies) and a virtual machine that can be run directly with minimum installation of ancillary software. We still welcome feedback on the use of these tools. For more information see the Forum.
