The committee is expect to provide guidance as the project proceeds. At the moment, observing strategies are still being discussed; this is where the committee’s guidance would be of great value. They will probably be a combination of deep pointing (mainly for absorption line studies), medium exposure of selected regions, and perhaps even an all-sky survey (at the later stage of the mission, which would have 2 eV energy resolution; for comparison, the eROSITA CCDs have an energy resolution of 60 - 70 eV at soft X-ray energies).

Technology trade-offs are also being made. For instance, energy range vs energy resolution, angular resolution vs field of view, all due to constraints of the detector technology chosen; lower upper energy bound and lower angular resolution would be less demanding on the detector system, but would have scientific implications. This is another area that the project needs guidance.

The committee is presently consisted of:

For the purpose of optimizing HUBS’ scientific output, the following Scientific Working Groups (SWGs) have been formed.

Colleagues who are interested in joining a SWG are encouraged to contact the chair(s) of the SWG directly. All are welcome!
