Special Issue Information
Dear Colleagues,
From the HEAO satellites nearly 50 years ago to the present cadre of active observatories— Chandra, XMM, Suzaku, NuStar, and eRosita—our view of the physics of structure formation has changed enormously. X-ray observations of superclusters, clusters, groups, and filaments have provided unprecedented insight into structure formation. Given the huge increase in spectral and spatial resolution, as well as sensitivity that has been achieved during this time, it is especially timely to present new results with an eye toward the most important issues in structure formation that should be addressed by future missions and the telescope–detector requirements needed to carry them out. In this Special Issue, we solicit contributions that address high energy emission from clusters, groups, and filaments: current observations and future prospects.
Topics include (but are not limited to):
- The physics of mergers and accretions including thermodynamic quantities (T,P,S) based on X-ray observations;
- Shock physics in the intracluster medium;
- The central region of clusters, in particular the AGN-ICM connection seen in X-ray cavities;
- Searches for the non-thermal signature in structure formation;
- Studies of the outskirts of the intracluster medium, including non-hydrostatic gas, accretion shocks, cool baryons;
- Studies related to uniformity of the average abundance in clusters and spatial deviations from solar abundance;
- Filamentary baryons;
- Structure in supercluster/filament systems;
- High redshift clusters of galaxies;
- The requirements for future X-ray missions (e.g., AXIS, Athena) to address the most compelling issues for galaxy clusters.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
