HYDRA: A New Paradigm for Astrophysical Modeling, Simulation, and Analysis (contd)
|
|
|
| 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 will provide scientists
a more flexible and extensible way of constructing models for
astrophysical sources that include 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, will be definable 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 observational
planning, instrument design, and calibration. Simultaneously, HYDRA
will provide an analysis environment that allows 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 that will provide users with additional
diagnostic ability as well as a potentially powerful educational tool. |
