Special Issue Information

Dear Colleagues,

The literature on extended and modified theories of gravity has grown enormously over the last decade: although the currently standard cosmological model accurately describes the power spectrum of the cosmic microwave background and the properties of cosmic structures at the scales of galaxies and beyond, our understanding of the nature of dark matter and dark energy is still unsatisfactory. In addition, some tensions on the galaxy scales and on the largest scales probed by the Planck mission are not yet easily accommodated into the general framework.

The current and upcoming wealth of data from ground and from space on the growth of cosmic structures, where the degeneracy among different cosmological models may be lifted, urges a comprehensive and deep understanding of the most promising modified theories of gravity and their accompanying cosmological models.

This special issue of Galaxies is intended to highlight the strengths and weaknesses of these models when compared to current and future data. We would like to call for papers on models beyond standard gravity and cosmology that explicitly address quantitative comparisons with observations. Review papers are also most welcome.

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Self-Gravitating Systems in Extended Gravity
Author: Arturo Stabile
Abstract: The first step of comparison between the General Relativity and the so-called Fourth Order Gravity must be performed in the same framework of astrophysical applications that demonstrated the validity of Einstein's theory with respect to the Newtonian mechanics. In this review we report the develop of the theory by extending the theory of General Relativity and recovering its modified outcomes. We consider other curvature invariants and also the presence of non-minimally coupled scalar field. The crucial point of the solutions for the spherically symmetric systems by assuming the hypothesis of weak field is particularly shown. In the second part of paper we report the astrophysical applications: the galactic rotation curves, the gravitational lensing, the stellar hydrostatic equilibrium. We conclude by analyzing the mathematical relations between the Jordan and Einstein frames.
