Special Issue Information
Dear Colleagues,
Primordial black holes, hypothesized to form in the early universe from the gravitational collapse of density fluctuations, represent a unique nexus of cosmology, gravitation and particle physics. This Special Issue will comprehensively explore the multifaceted role of primordial black holes, from their genesis to their ultimate demise and profound implications.
We will solicit contributions detailing modern mechanisms for primordial black hole production, including inflationary models and cosmological phase transitions. A core focus will be the physics of primordial black hole evaporation via Hawking radiation, examining its potential role as a progenitor for dark matter, a source for baryogenesis or a contributor to the cosmic gamma-ray background. Furthermore, the Issue will investigate the cosmological consequences of primordial black holes, encompassing their impact on Big Bang Nucleosynthesis, the cosmic microwave background and their potential to seed large-scale structures or account for the supermassive black holes observed at high redshifts. By uniting these diverse research threads, this collection aims to critically assess the current status of primordial black hole science and define the observational avenues that will confirm or constrain their existence, thereby shaping our understanding of the early universe and fundamental physics.

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.
