Use case: interpreting structure of X-Ray clustersDescriptionA 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 actorX-Ray astronomerEnd result:Mock temnperature and pressure images are obtained from simulated galaxy cluster ready for comparison to real X-Ray observations.Other actors:SimulatorPre-conditions
