Signals in the Universe: Variable Stars and Transients as Physics Gauges

Dear Colleagues,

We are so excited to invite the astronomical community to contribute to the Special Issue hosted by GALAXIES: “Signals in the Universe: Variable Stars and Transients as Physical Gauges”. The role of variable phenomena in the Universe as indicators of cosmic distances and other physical parameters is, in the most general way, at the very foundation of modern astrophysics. Right from the discovery of the first variable stars, through the well-known P-L relation of classical Cepheids discovered by Mrs. Leavitt, up until the most dramatic detection of gravitational waves produced by colliding black holes, variable phenomena in Astronomy have fundamentally contributed in many ways to a profound understanding of the physical Universe.

We aim to bring together contributions on topics related to variable stars and transient phenomena and their impact as indicators of local and global astrophysics. We shall be delighted in including theoretical, observational and numerical contributions and review-style articles related to one or more of the following sub-topics:

- Galactic and extragalactic variable stars;

- Variable stars in stellar clusters and associations;

- Radio burst sources in  globular clusters;

- Gamma-ray bursts;

- Flare stars;

- Pulsars;

- Novae ans Supernovae;

- Changing active galactic nucleus (AGN) activity;

- Transits and extrasolar planetary systems;

- Gravitational microlensing;

- Gravitational waves.

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 250 words) can be sent to the Editorial Office for assessment.

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.
