Special Issue Information
Dear Colleagues,
Fast radio bursts (FRBs) are mysterious radio transients of millisecond duration and with extremely high brightness temperatures. Since their first discovery in 2007, more than 100 FRBs have been detected, and FRBs are now well-established as extragalactic sources. Driven by groundbreaking observation results from radio observatories all over the world, numerous theoretical models have been proposed to interpret these mysterious events. In 2020, a galactic FRB, FRB 200428, was detected by CHIME and STARE2 in association with a hard X-ray burst from a galactic magnetar, SGR J1935+2154, during its active phase. This discovery established magnetars as a source that can produce FRBs. On the other hand, as radio transients, their observation properties (dispersion measure, rotation measure, scattering tails, scintillation, etc.) are affected by the medium along the line of sight. Therefore, FRBs are powerful tracers of circumburst environments. Located at cosmological distances, FRBs also have great potential as probes of cosmology, including "missing baryons" in the intergalactic medium, dark matter, etc. The current state of the FRB field is exciting, and the advent of multi-messenger observations and surveys will boost the progress of FRB studies in the future.
The purpose of this Special Issue of Galaxies is to provide an overview of the main challenges and issues that the FRB field is currently confronted with, including the physical origin, propagation, observation properties, and statistical characteristics of FRBs. Original research articles and reviews are welcome. We look forward to receiving your contributions. Let's work together to find out what FRBs are!

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.
