Special Issue Information
Dear Colleagues,
The structural properties of galaxies encode the imprint of their formation and the physical processes that shape their evolution. Recent advances in wide-field imaging have transformed our ability to study galaxies across a broad range of physical characteristics. Contemporary surveys now provide homogeneous, high-resolution datasets that enable detailed characterization of galaxy morphology, stellar mass distributions, kinematics, and substructures, revealing a far more complex picture of galactic assembly than previously appreciated.
However, many fundamental questions remain. The origins and evolution of disks, bulges, bars, nuclear components, and diffuse stellar halos are still debated. Moreover, linking observed structural properties with cosmological simulations continues to remain a challenge.
The era of wide-field surveys offers an unprecedented opportunity to advance this field. Facilities such as JWST, the Vera C. Rubin Observatory’s LSST, Euclid, and the forthcoming Nancy Grace Roman Space Telescope will deliver data of exceptional depth and uniformity, enabling structural measurements for millions to billions of galaxies and opening the door to large-scale and detailed studies of galaxy structure.
We invite contributions spanning observational analyses, structural modeling, galaxy simulations, and methodological developments. Topics of interest include, but are not limited to, the following: morphological classification and photometric decomposition; galaxy scaling relations and their physical origins; the formation and evolution of bulges, disks, bars, and stellar halos; environmental effects on galaxy structure; low-surface-brightness components; machine learning approaches to morphological analysis; multi-wavelength structural characterization; and comparisons between observations and cosmological simulations. By bringing together diverse perspectives and approaches, this Special Issue aims to provide a comprehensive view of the current landscape of galaxy structural studies in the wide-field survey era.

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.
