EROSITA是2019年7月在Spektr-RG卫星上发射的X射线望远镜，首次在0.2-10.0keV的X射线波段进行成像全天测量。研究股将由Rosita联盟的核心研究所成员组成，将致力于研究恒星终点，即白矮星、中子星、黑洞以及超新星遗迹和银河系和麦哲伦云中的星际介质的X射线辐射。基于eROSITA全天巡天的数据，我们将调查漫射X射线辐射的来源和性质，以及星系中的X射线源群。在研究股的第一个资助期内，将使用eROSITA观测整个天空6至7次(全天调查4年中的3.5次)。我们将为每个项目制定具体的分析方法，并对更亮的物体或瞬变源进行研究。该研究组的长期目标是对银河系和麦哲伦星云中的X射线源进行全面的普查和理解，直到流量极限F=10^-14 erg cm^-2 S^-1，约束大型星际结构的物理学，并提高我们对星际冲击和粒子加速的理解。我们将获得SDSS或4MOST等光学调查的补充数据和额外的多波长观测。将在研究股的项目中开发的分析方法和软件也将使eROSITA联盟和广大科学界都能充分利用eROSITA全天观测。

eROSITA (extended ROentgen survey with an Imaging Telescope Array) is an X-ray telescope which was launched onboard the Spektr-RG satellite in July 2019 and carries out the first imaging all-sky survey in the X-ray band of 0.2 - 10.0 keV. The Research Unit will be formed by members of the core-institutes of the ROSITA consortium and will be dedicated to the study of X-ray emission of stellar endpoints, i.e., white dwarfs, neutron stars, black holes, as well as supernova remnants and the interstellar medium in the Milky Way and the Magellanic Clouds. Based on data of the eROSITA all-sky survey we will investigate the origin and nature of the diffuse X-ray emission and the X-ray source populations in galaxies. During the first funding period of the Research Unit, the entire sky will be observed with eROSITA 6 to 7 times (3.5 of 4 years of the all-sky survey). We will develop specific analysis methods for each project and carry out studies of, e.g., brighter objects or transient sources. The long-term aim of the Research Unit is to have a complete census and comprehension of X-ray sources in the Milky Way and the Magellanic Clouds down to a flux limit of F = 10^-14 erg cm^-2 s^-1, to constrain the physics of large interstellar structures, and to improve our understanding of interstellar shocks and particle acceleration. We will have access to complementary data of optical surveys like SDSS or 4MOST and additional multi-wavelength observations. The analysis methods and soft wares, which will be developed in the projects of the Research Unit will also allow both the eROSITA consortium and the broad science community to fully exploit the eROSITA all-sky survey.
