对致密物体的高时间分辨率x射线观测提供了对强场引力、超致密物质状态方程以及黑洞质量和自旋的直接访问。需要一台10平方米级的仪器，并结合良好的光谱分辨率来进行相关诊断，并回答欧洲航天局（ESA）宇宙视野主题“极端条件下的物质”的两个基本问题，即：靠近事件视界的物质轨道是否遵循广义相对论的预测？中子星的物质状态方程是什么？大型x射线计时天文台（LOFT）被ESA选为四个宇宙视野M3候选任务之一，将进行评估阶段，它将彻底改变我们银河系中坍缩物体和活动星系核中最亮的超大质量黑洞的研究。由于创新的设计和大面积单片硅漂移探测器的发展，LOFT上的大面积探测器（LAD）将在2-30 keV范围内（扩展模式下可达50 keV）实现~12 m2的有效面积（比任何星载前身都大一个数量级），但仍然适合传统平台和中小型发射器。在如此大的面积和<260 eV的光谱分辨率下，LOFT将在极端压力和磁场强度条件下获得关于强弯曲时空和物质的前所未有的信息。
High-time-resolution X-ray observations of compact objects provide direct access to strong-field gravity, to the equation of state of ultradense matter and to black hole masses and spins. A 10 m2-class instrument in combination with good spectral resolution is required to exploit the relevant diagnostics and answer two of the fundamental questions of the European Space Agency (ESA) Cosmic Vision Theme “Matter under extreme conditions”, namely: does matter orbiting close to the event horizon follow the predictions of general relativity? What is the equation of state of matter in neutron stars? The Large Observatory For X-ray Timing (LOFT), selected by ESA as one of the four Cosmic Vision M3 candidate missions to undergo an assessment phase, will revolutionise the study of collapsed objects in our galaxy and of the brightest supermassive black holes in active galactic nuclei. Thanks to an innovative design and the development of large-area monolithic silicon drift detectors, the Large Area Detector (LAD) on board LOFT will achieve an effective area of ~12 m2 (more than an order of magnitude larger than any spaceborne predecessor) in the 2–30 keV range (up to 50 keV in expanded mode), yet still fits a conventional platform and small/medium-class launcher. With this large area and a spectral resolution of <260 eV, LOFT will yield unprecedented information on strongly curved spacetimes and matter under extreme conditions of pressure and magnetic field strength.
