For Scientists: IXPE Users' Committee.


The purpose of the IUC is to help ensure that interests of General Observers (GOs) and other scientists who use IXPE data are served by the IXPE mission. The IUC serves as the primary means by which the IXPE user community can communicate with the IXPE Project and NASA Headquarters (HQ). The IUC will also assist the IXPE project prepare for future NASA Astrophysics Senior Reviews of Operating Missions.

The IUC shall review and provide findings with respect to these key areas:

  • data analysis software, proposal preparation tools, and user support,
  • data distribution issues,
  • calibration considerations and products,
  • planning for announcements, selection, and execution of GO programs,
  • balance of funding between GO observing and theory programs,
  • dissemination of IXPE science results through meetings and community outreach.
The IXPE Users' Committee (IUC) is currently made up of seven astrophysicists, two of whom are members of the IXPE prime mission science team (asterisked). Meetings are public and non-members may join in. IUC members are:
  • Eileen Meyer (chair), University of Maryland, Baltimore County, USA
