The enhanced X-ray Timing and Polarimetry (eXTP) and The Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) missions |
|
Abstract |
eXTP is a science mission designed to study the state of matter under extreme conditions of density, gravity and magnetism. Primary goals are the measurement of the equation of state of matter at supra-nuclear density, the study of QED effects in highly magnetized star and the study of accretion processes in the strong-field regime of gravity. The mission carries an unprecedented suite of instruments enabling for the first time simultaneous spectral-timing-polarimetry studies in 0.5-30 keV: the the Spectroscopic Focusing Array, the Large Area Detector, the Polarimetry Focusing Array and the Wide Field Monitor. The eXTP international consortium includes major institutions of the Chinese Academy of Sciences and Universities in China, as well as major institutions in several European countries. The planned launch date of the mission is 2025. The Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) is a proposed NASA Probe class mission aimed at the extremes of high throughput X-ray astronomy, making use of an 8 m2 total collecting area, CCD-quality spectral resolution, and a state-of-the art wide field monitor with both very large instantaneous sky coverage and good intrinsic spectral and time resolution. The core goals are time domain astrophysics and high count spectroscopy. Its capabilities span a broad range of topics, including those traditional to X-ray timing missions, like probing strong gravity for stellar mass to supermassive black holes and ultradense matter with unprecedented effective area, high time-resolution, and good spectral resolution, while providing a powerful time-domain X-ray observatory. |
