The 858th WE-Heraeus Seminar "Galactic Frontiers 2026: Advancing X-ray Astronomy in a Multiwavelength Universe" will bring together leading and early-career researchers to discuss the latest advances in Galactic X-ray astronomy enabled by missions such as eROSITA, XMM-Newton, Chandra, XRISM and other flagship missions. Topics include, among others, stars and stellar populations in the X-ray domain, diffuse X-ray emission in the interstellar medium, supernova remnants and their role in feedback processes, and the population and evolution of compact objects (white dwarfs, neutron stars, black holes).

A key focus will be the synergy between X-ray studies and observations across the electromagnetic spectrum - from radio to gamma rays - as well as the growing contributions of amateur astronomy networks to wide-field optical searches for extended nebulae and SNRs.

The seminar will be held from 15–18 June 2026 at the Physikzentrum Bad Honnef. The program will include invited overview talks, contributed presentations, poster sessions, and dedicated reporter talks that summarize the key results from selected posters. A concluding excursion to the Effelsberg 100-m Radio Telescope, operated by the Max Planck Institute for Radio Astronomy, is planned. The event is designed to foster multi-wavelength collaboration and to provide a stimulating forum for researchers at all career stages.

Invited review talks and selected papers are planned to be published as refereed proceedings.
