ARTIST (Adaptable Radiative Transfer Innovations for Submillimeter Telescopes) is a set of two CASA tools that allow you to
- select one of nine pre-coded astrophysical models describing young stellar objects, planet forming disks, or circumstellar shells;
- adapt the parameters of these models;
- calculate the excitation of a user-selected molecule using the LIME (LIne Modeling Engine) accelerated monte-carlo code;
- and calculate the (sub) millimeter line emission of this object at a specified distance and orientation.
The output is a FITS cube that can be further processed within CASA, for example to create mock ALMA observations for proposal preparation and data analysis.
ARTIST was originally developed under contract from ASTRONET by the universities of Bonn, Copenhagen, and Leiden, the Onsala Space Observatory and the
Institute of Space Sciences (IEEC-CSIC). LIME was developed originally by Christian Brinch. The CASA implementation of ARTIST was developed under contract with ESO as an ALMA Development study (56787/14/60579/HNE).
