The Journal of High Energy Astrophysics (JHEAP) is the first astrophysical journal that focuses on the study of the most energetic phenomena.Driven by observations conducted with unprecedented experimental facilities and satellites, the last few years have brought a plethora of historic results at the high-energy end of the electromagnetic spectrum, as well as breakthrough, first observations with neutrinos and gravitational waves.This scenario appeal to new theoretical efforts, altogether leading to a burst of new ideas, problems, and research directions.High-energy astrophysics, a research field that connects astronomy, cosmology, and particle physics, will continue to expand in the next decades, boosted by forthcoming improvements in experimental detection precision.JHEAP seeks scientifically sound papers, and particularly those crossing strict specialization fields, attracting wide interest.The journal welcomes manuscripts on theoretical models, simulations, and observations of energetic astrophysical objects both in our Galaxy and beyond. Among those, black holes at all scales, neutron stars, pulsars and their nebula, magnetars, fast radio bursts, binaries, novae and supernovae, their remnants, active galaxies are just a few examples.The journal will consider research across the whole electromagnetic spectrum, as well as research using various messengers, such as gravitational waves or neutrinos.Effects of high-energy phenomena on cosmology and star-formation, results from dedicated surveys expanding the knowledge of extreme environments, and astrophysical implications of dark matter are also welcomed topics.The journal adopts the commonly used single blind peer review system, during which the reviewer names are kept anonymous while the author or collaboration name is disclosed to the reviewers. In addition, the journal introduces the possibility for papers to be refereed in a double-blind process, in order to ensure and promote quality. A dedicated reviewer pool, an active Editorial Board, a fast and traceable online submission procedure.Starting from October 2023, the journal implements a Letters column, which disseminates timely and impactful results in the field. There is no length limit to the Letters. A speed-up refereeing process (typically in 2 weeks) is reinforced. The authors have an option to choose Letters submission. The scientific editors will check its suitability to the Letters column and decide whether it is sent out for review as a Letter or a regular article.JHEAP has no page charges and has a delayed open access model, meaning that your article will automatically and without extra charge become open access after 12 months.All colour figures are free for the online version and a selection of printed colour figures costs may be waived at the Editor's discretion. JHEAP is indexed in all major systems such as Scopus, Web of Science and SAO/NASA Astrophysics Data System (ADS).JHEAP only publishes professional, verifiable, and reproducible research and does not welcome articles just expressing personal opinions.
