Programme of session included (May 1) - Programme updated (June 14)

The eXTP (enhanced X-ray Timing and Polarimetry) mission is a major project of the Chinese Academy of Sciences (CAS), with a large involvement of Europe and expected ESA support. It is designed to study the state of matter under extreme conditions of density, gravity and magnetism, as for instance what is happening on the vicinity of black holes or what is the state of matter inside neutron stars. Its predicted launch is in 2027. eXTP will carry a unique suite of instruments, enabling for the first time ever the simultaneous spectral-timing-polarimetry studies of cosmic sources in the energy range from 0.5 to 30 keV. The eXTP scientific payload includes four instruments: SFA (Spectroscopy Focusing Array), PFA (Polarimetry Focusing Array), LAD (Large Area Detector) and WFM (Wide Field Monitor). The SFA, PFA and LAD offer an unprecedented simultaneous wide-band X-ray timing and polarimetry sensitivity. The WFM will be a wide field X-ray monitor instrument in the 2-50 keV energy range, with an unprecedented combination of large field of view and imaging down to 2 keV; it will allow eXTP to make important discoveries of the variable and transient X-ray sky, and outstanding contributions to multi-messenger astronomy.

A large European consortium (Austria, Czech Republic, Denmark, France, Germany, Italy, Poland, Spain, Switzerland, The Netherlands, and Turkey) is contributing to the eXTP study, both for the science and the instrumentation, providing two of the four instruments: LAD and WFM (led by Italy and Spain, respectively). The WFM for eXTP will be a wide field X-ray monitor instrument in the 2-50 keV energy range. Its unprecedented combination of large field of view and imaging down to 2 keV will allow eXTP to make important discoveries of the variable and transient X-ray sky, outstanding contributions to multi-messenger astronomy. A special session on eXTP in the framework of the EAS is a unique opportunity to update the European and worldwide community about the progress of the mission and its exciting science output.

The session will be mainly organized as a series of invited talks to cover the program, but we will also welcome other contributions (mainly posters, because of the limited time available).
