Hairy Black Holes: Insights and Advances

Dear Colleagues,

Hairy black holes are reshaping our understanding of gravity, challenging the traditional no-hair conjecture and revealing new dynamics within and beyond General Relativity (GR). These solutions, supported by scalar, vector, or tensor fields, open exciting opportunities to test fundamental physics, explore modified gravity, and connect to quantum gravity.

This Special Issue, “Hairy Black Holes: Insights and Advances,” invites cutting-edge contributions on:

1) Hairy black holes in GR and beyond (e.g., Einstein–scalar–Gauss–Bonnet gravity);
2) Stability and dynamical properties;
3) Observational signatures from gravitational waves, black hole shadows, and accretion disks (LIGO/Virgo, EHT, future missions);
4) Quantum aspects and holographic perspectives;
5) Implications for dark matter and the no-hair theorem.

We welcome both original research and comprehensive reviews. By uniting analytical, numerical, and phenomenological approaches, this issue aims to serve as a reference for researchers exploring the rich physics of black holes endowed with “hair”.

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. 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.
