Special Issue Information
Dear Colleagues,
This Special Issue of Galaxies is intended to bring together papers on recent advances in understanding the physics of blazars through multifrequency variability. Papers covering frequency ranges from radio through gamma rays and timescales from microvariability to long-term variability (years) are encouraged. Observations and theories of line variability as well as continuum variability are encouraged. The physics behind these observations link the basic components of current AGN models: disk processes, jet processes, and broad line region processes. Bringing all of these together in a Special Issue highlights the current state of knowledge of these intriguing physics laboratories.

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 1500 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.
