Recent Advances in Gamma Ray Astrophysics and Future Perspectives

Dear Colleagues,

In recent decades, a variety of sources have been discovered for gamma-ray astrophysics above a few tens of GeV up to the PeV regime.While in the TeV energy band, we only have a few hundred sources, at lower energies, we have now started population studies thanks to the relatively high number (a few thousands) of both galactic and extragalactic gamma-ray emitters.

Gamma-ray sources not only show transient, periodic, flaring or steady emission levels but could be detected almost across the entire electromagnetic spectrum, making them excellent targets for multifrequency studies.

The present Special Issue aims to host several contributions (both theoretical and observational) dealing with diverse aspects related to the frontiers in gamma-ray research. Potential topics include but are not limited to:

• Gamma-ray bursts;
• Accreting binaries;
• Supernova remnants;
• Active galactic nuclei;
• Transients;
• Ground-based instrumentation for gamma-ray astrophysics;
• Space-based instrumentation for gamma-ray astrophysics;
• Software and infrastructure for gamma-ray astrophysics.

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 250 words) can be sent to the Editorial Office for assessment.

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.
