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.

eROSITA（带成像望远镜阵列的扩展伦琴巡天）是一架x射线望远镜，于2019年7月在Spektr-RG卫星上发射，并在0.2 - 10.0 keV的x射线波段进行首次成像全天巡天。该研究单位将由ROSITA联盟核心研究所的成员组成，并将致力于研究恒星端点的x射线发射，即白矮星、中子星、黑洞、超新星遗迹以及银河系和麦哲伦星云中的星际介质。基于eROSITA全天巡天数据，我们将研究漫射x射线的起源和性质以及星系中的x射线源种群。在研究小组的第一个资助期内，将使用eROSITA对整个天空进行6至7次观测（4年全天巡天的3.5次）。我们将为每个项目制定具体的分析方法，并开展研究，例如，更亮的物体或瞬态光源。该研究单位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，直至通量极限为F = 10^-14 erg cm^-2 s^-1，以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等光学巡天的补充数据以及额外的多波长观测数据。分析方法和软件，将在研究单位的项目中开发，也将使eROSITA联盟和广泛的科学界充分利用eROSITA全天调查。
