Special Issue Information
Dear Colleagues,
Among the most important reasons for considering the extended theory of Einstein gravity is related to the discovery of the accelerated expansion of our universe, because general relativity provides an insufficient explanation. In this regard, various candidates have been proposed, such as Lovelock gravity, brane world cosmology, scalar–tensor theories, and F(R) gravity. Compact astrophysical objects probe extreme gravitational fields and may be the key to understanding unanswered questions in fundamental physics. The neutron and quark stars, gravastars, and massive white dwarfs are categorized as celestial objects with a high mass and small radius (high density), and, therefore, they are called compact astrophysical objects. Therefore, we must take into account the effects of space–time curvature for investigating their structures. On the other hand, the recent discovery of massive compact objects (such as pulsars, neutron and quark stars, and white dwarfs) contributes to the motivation to study these compact objects in extended theories of gravity, since apparently these massive objects cannot be predicted within general relativity formalism. Potential topics include, but are not limited to, the following: the structure and properties of neutron, quark and boson stars, and (massive) white dwarfs in extended theories of gravity; the properties of gravastars in extended theories of gravity, black hole solutions, and study of the parameters of extended theories of gravity in these solutions.

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. Galaxies is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). 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.
