Special Issue Information
The Cosmic Microwave Background is one of the fundamental pillars in our understanding of the universe. This electromagnetic radiation encodes information on the very early processes that occurred at the first stages of the universe, its content and thermal history. The success of ground experiments, balloons, and space missions has settled the cosmological model that describes the origin and evolution of our universe with unprecedented precision. But also it contains information of what happened between its formation and the travel to the observer, all of it affected by the galactic diffuse emission or by extragalactic radiosources. The non-achieved detection of the primordial B-modes (sourced by the primordial stochastic gravitational wave background generated during inflation) has opened an important effort for characterizing the polarization of the CMB, in particular, the polarized foreground emission, mainly coming from synchrotron and dust emissions of our galaxy, though other polarized signals could mask the primordial one as the lensing effect due to the large scale distribution. This Special Issue is devoted to current advances in CMB studies, which cover a wide range of the physics of the early universe, and also to the modeling of the diffuse emission of our galaxy that becomes a crucial foreground for detecting or constraining primordial B-modes as well as other effects as reionization, lensing and so on that could mask that primordial signal in polarization.

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. Symmetry is an international peer-reviewed open access monthly 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 2400 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.
