The present status of the JEM-X instruments will be briefly reviewed as well as the main characteristics for the science data quality. At "DTU Space" we are engaged in a science program on X-ray burst detection and interpretation. A large number of bursts from neutron stars near the galactic center have already been recorded and the search effort continues. The analysis aims at a determination of the burning processes involved and building a comprehensive catalog. The latest results and future prospects are reviewed. A new image building and analysis technique is under development for a better separation of sources and background. Based on the large amount of data from the eight years of INTEGRAL operation the diffuse X-radiation can be mapped on an angular scale finer than e.g. ISGRI and in a lower energy band. The emphasis is on the emission from the galactic ridge. Results from these investigations are presented. As an introduction to the source catalog production, the status of the existing catalogs is reviewed with comments on source detection sensitivity, sky coverage, and level of detail in the final product.
