HYDRA: A New Paradigm for Astrophysical Modeling, Simulation, and Analysis
|
|
|
| Regardless of the source or mission, the analysis of astrophysical data invariably relies on the interplay between predictive physical models, a detailed understanding of the observing instruments, and the discriminating comparison of predictions and actual observations. With HYDRA, we are developing a new platform which provides scientists a more flexible and extensible way of constructing models for astrophysical sources including geometric information, physical emission and absorption mechanisms, transport processes, and projection effects. We will also provide an interface through which users may link existing astrophysical models to HYDRA. Similarly, modules describing the performance of the instrumentation, be it ground-based telescope or orbiting satellite, can be defined in a mission-independent way to allow realizations of these models in the form of simulated observations. By combining source and instrumentation models, HYDRA can serve as a tool for both observational planning and instrument design and calibration. Simultaneously, HYDRA provides an analysis environment allowing source models to be compared to existing observations and iteratively adjusted. As part of its design, the HYDRA system will also include advanced visualization capabilities providing users with additional diagnostic ability as well as a potentially powerful educational tool. |
