In Pursuit of Supernova Remnants
Supernova remnants (SNRs) have a profound influence on the interstellar medium (ISM) through the formation of strong shocks, the injection of heavy elements, and the acceleration of cosmic rays. Over the past decade, observational and theoretical studies have increasingly demonstrated that the inhomogeneous nature of the surrounding ISM is essential for understanding a wide range of high-energy physical processes associated with SNRs.
Dense interstellar clouds can survive shock erosion and subsequently produce hadronic gamma-ray emission and amplify magnetic turbulence. High-resolution X-ray spectroscopy has revealed emission signatures associated with interactions with cold ISM clouds, as well as complex and asymmetric motions of plasma and ejecta. In parallel, magnetohydrodynamic simulations have introduced a new perspective on shock propagation through a clumpy medium, enabling direct and quantitative comparisons between numerical models and observations.
Providing regular opportunities for observers and theorists to gather, share recent results, and engage in in-depth discussions on supernova remnants (SNRs) is therefore critically important, not only for advancing our scientific understanding but also for fostering the long-term vitality of the research community.
This 13th workshop continues to place SNRs at its core, while also highlighting other astrophysical sources that are expected to host similar high-energy processes, such as microquasars and gamma-ray binaries, which are promising PeVatron candidates. Building on the methodologies and insights developed through SNR studies, the workshop will explore a broad range of open questions in high-energy astrophysics, including the origin of cosmic rays.
We hope that this workshop will serve as a fruitful forum for meaningful exchange among researchers and contribute to deeper insight into the fundamental physics of SNRs and related high-energy phenomena.
