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（扩展的伦琴巡天成像望远镜阵列）是一款 X 射线望远镜，于 2019 年 7 月在 Spektr-RG 卫星上发射，在 0.2 - 10.0 keV 的 X 射线波段进行首次成像全天巡天。该研究小组将由ROSITA联盟核心研究所成员组成，致力于研究恒星端点的X射线发射，即白矮星、中子星、黑洞以及超新星遗迹和恒星。银河系和麦哲伦云中的星际介质。基于 eROSITA 全天巡天数据，我们将研究漫射 X 射线发射的起源和性质以及星系中的 X 射线源群。在研究单位的第一个资助期间，将使用 eROSITA 观测整个天空 6 至 7 次（全天空巡天 4 年中的 3.5 次）。我们将为每个项目开发具体的分析方法，并对较亮的物体或瞬态源等进行研究。研究小组的长期目标是对银河系和麦哲伦星云中的 X 射线源进行完整的普查和理解，直至通量限制为 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。我们将可以获得 SDSS 或 4MOST 等光学调查的补充数据以及其他多波长观测数据。研究单位项目中将开发的分析方法和软件也将使 eROSITA 联盟和广大科学界能够充分利用 eROSITA 全天巡天。
