Use case: interpreting structure of X-Ray clusters
Description
A user has obtained and analysed a detailed X-Ray image of a galaxy cluster and derived temperature and pressure maps from them
(see for example Schuecker
et al, 2004). Using locally developed statistical techniques small scale
sub-structure is investigated and an interpretation in terms of a turbulent intra cluster medium is proposed. To investigate whether this interpretation is realistic a similar analysis is desired on simulated images. This requires availability of hydro simulations of galaxy clusters with the appropriate physics included and services that can create mock temperature and pressure images from this simulation. For an example of such a service see the
GAVO website.
primary actor
X-Ray astronomer
End result:
Mock temnperature and pressure images are obtained from simulated galaxy cluster ready for comparison to real X-Ray observations.
Other actors:
Simulator
Pre-conditions
- A registry searchable for simulations filtered on physical properties and services for producing images.
- An environment allowing configuration and execution of the services.
Flow of events
- User browses registry for appropriate virtual telescope service based on simulation and service meta-data
- Selects service and provides input
- Service executes and provides (links to) results
Post-condition
- Mock images provided in standardized format, for example FITS
Basic assumptions
Alternative flows
