Special Issue Information
Dear Colleagues,
The advent of the discovery of the first gravitational wave (GW) signal due to the merger of two black holes by the experimental LIGO and VIRGO collaborations in 2015 has pushed us into a new era. There has also been the detection of a number of binary coalescence signals, along with the detection of the merger of two black holes with a wide and continuous range of composite stellar size masses. In addition to these discoveries, there are many other astrophysical sources which will yield detectable GW signals that will lead to, in the near future, terrestrial experiments. Finally, another source of GWs is the stochastic gravitational wave background (SGWB) in our universe, which contains many subcomponents. Firstly, there is a component which is purely astrophysical in nature and consists of the random superposition of individually unresolved signals from all the families of astrophysical sources mentioned above. Additionally, there are other exciting possibilities contributing to the cosmological origins of the GWs. Some of which include first-order phase transitions (FOPTs) in the early universe, inflation, or topological defects such as cosmic strings and domain walls.
In this Special Issue we will be focusing on the recent advances made with such origins, and also, various paradigms of models responsible for such signals.

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. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. 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.
