Seyfert Galaxies: Probing the Active Nuclei of Nearby Galaxies

Dear Colleagues,

Seyfert galaxies are a subclass of active galactic nuclei (AGNs) characterized by the presence of actively accreting supermassive black holes at their centers. These galaxies exhibit high luminosities, particularly in the optical, ultraviolet, and X-ray bands, making them crucial objects for understanding the processes governing AGN activity and galaxy evolution. Due to their relative proximity, Seyfert galaxies offer a unique opportunity to observe the mechanisms fueling black hole accretion and to explore how this activity interacts with other galactic components.

Over the past several decades, Seyfert galaxies have served as astrophysical laboratories for investigating the complex interplay among black hole growth, star formation, and feedback processes within the interstellar medium. Their observable characteristics—such as emission line regions, radio jets, and variability—allow researchers to probe the physics of accretion disks, narrow-line and broad-line regions, and host galaxy morphology with high spatial and spectral resolution.

Furthermore, by comparing the properties of nearby Seyfert galaxies with those of more distant, early-formed galaxies, we gain insights into the cosmic evolution of AGNs and their role in the reionization and chemical enrichment of the universe. This Special Issue aims to bring together recent advances in observational and theoretical studies of Seyfert galaxies to deepen our understanding of AGN–host galaxy co-evolution across cosmic time.

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-anonymized 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.
