Special Issue Information
Dear Colleagues,
Modern cosmology is constructed by adopting the cosmological principle, and is currently based on the six-parameter minimal ΛCDM paradigm. The model has passed several experimental tests, and is statistically favored with respect to alternative dark energy parameterizations. However, current tensions among cosmological parameters and the recent debate regarding possible departures from the cosmological principle have raised doubts about its validity at all scales of the universe’s evolution.
Moreover, although appealing and well-consolidated, the ΛCDM model shows strong discrepancies between quantum expectations and cosmic observations. Hence, the ΛCDM model could be somehow incomplete, suggesting that in the field of actual precision cosmology we may require a complete restyling of the cosmological puzzle, as it appears highly plagued by theoretical shortcomings.
This Special Issue intends to explore research articles focusing on current issues of modern cosmology and astrophysics, investigating early, intermediate and late times of the universe’s evolution and proposing alternatives to the standard cosmological scenario. This Special Issue focuses on the study of cosmological models, early-time cosmology, simulations in cosmology, numerical approaches to cosmology, dark matter distribution, small perturbations, solutions to the cosmological constant problem, dynamical systems in cosmology, quantum cosmology, extended theories of gravity, modified theories of gravity, etc. We also welcome the study of relativistic astrophysics in a broad sense. In this respect, wormhole physics, black hole physics, strange stars, gamma-ray bursts, relativistic thermodynamics, non-equilibrium thermodynamics and all possible applications to cosmology are emphasized in this Special Issue.
We also expect to receive review articles describing the current state-of-the-art within this broad subject.

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.
