Special Issue Information

Dear Colleagues,

The field of Fast Radio Bursts (FRBs) is one moving at a surprising pace. Discovered in 2007, with a one-off burst, this adolescent population now counts ~600 (published) members, among which a small fraction (~20) repeat.

The availability of new and dedicated instrumentation and techniques, offering unprecedented on-sky time and processing capabilities, has led to a revolution in the field in a matter of a few years.

This Issue will address the latest advances in observations and methods and it will cover some of the latest developments in theory and cosmology.

The Issue will include, but not be limited to:

  • Repeaters vs. one-offs: an observational bias?
  • FRB periodicity: what have we learned from it?
  • The Interstellar and Intergalactic medium: the perspective of FRBs
  • New facilities and how they look at FRBs
  • Where does the parameter space of transients extend to?
  • Traditional vs. future methods to look for fast transients
  • What have we learnt from FRB localisation?
  • What are FRBs best for in cosmology?
  • FRBs and magnetars: in which ways are they related?

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.

Ephemeral Fast Radio Bursts (FRBs) must be powered by some of the most energetic processes in the Universe. That makes them highly interesting in their own right, and as precise probes for estimating cosmological parameters. This field thus poses a unique challenge: FRBs must be detected promptly and immediately localised and studied based only on that single millisecond-duration flash. The problem is that the burst occurrence is highly unpredictable and that their distance strongly suppresses their brightness. Since the discovery of FRBs in single-dish archival data in 2007, detection software has evolved tremendously. Pipelines now detect bursts in real time within a matter of seconds, operate on interferometers, buffer high-time and frequency resolution data, and issue real-time alerts to other observatories for rapid multi-wavelength follow-up. In this paper, we review the components that comprise a FRB search software pipeline, we discuss the proven techniques that were adopted from pulsar searches, we highlight newer, more efficient techniques for detecting FRBs, and we conclude by discussing the proposed novel future methodologies that may power the search for FRBs in the era of big data astronomy.
