The 10th Anniversary of Galaxies: New Perspectives on Radio Surveys

Dear Colleagues,

Large-scale radio-frequency surveys offer a unique window to the nearby and distant universe. For instance, radio-wavelength observations of ionized and neutral gas tracers enable the study of galactic and extragalactic star formation, which is not easy to achieve at other wavelengths. Moreover, these surveys provide information about the various emission components of the interstellar medium, such as synchrotron, free–free, and thermal-dust emission. Furthermore, radio surveys that cover large areas of the sky are key to assembling comprehensive and statistically representative samples of both  galactic and extragalactic objects.

In light of the present radio facilities such as FAST, LOFAR, GMRT, MWA, VLA, ALMA, and MeerKAT, and the advent of forthcoming instruments such as ngVLA and SKA, we expect new breakthroughs in many fields of astronomy. In particular, using such instruments, the increased sensitivity, larger frequency, and greater sky coverage of ongoing and upcoming radio surveys will enable researchers to address important astrophysical problems.

New opportunities brought about by large-scale radio surveys have mainly been presented in conference proceedings. However, we hope that a comprehensive collection of peer-reviewed research contributions on this topic will highlight future (immediate and long-term) achievements. The aim of this Special Issue is to present the current state of radio surveys and explore future developments and potential applications brought about by enhanced radio antennas and radio arrays.

We invite the astronomical community to submit contributions in the form of both original research and review articles. Potential topics include, but are not limited to: i) surveys of ISM and IGM structures (e.g., molecular clouds, YSOs, HII regions, evolved stars, and supernova remnants), their interplay with star formation, and their role in galaxy formation and evolution; ii) extragalactic surveys (e.g., to study star-forming galaxies at high redshift, and AGN evolution);  iii) cosmology surveys  (e.g., CMB polarization, dark ages, the epoch of reionization, and large-scale structures); and iv) dark matter surveys.

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.
