Symmetry in Dark Matter and Black Holes

Dear Colleagues,

Symmetry is a fundamental concept in physics and plays a crucial role in understanding various phenomena, especially gravity at large scales. On the cosmic scale, two prominent phenomena are dark matter and black holes. Dark matter, which constitutes a significant portion of the universe, and black holes, which represent intriguing strong gravitational effects, both exhibit inherent symmetries that are essential for a comprehensive understanding of these phenomena. The recent advancements in the field, particularly in the observations of gravitational waves and the imaging of black holes, have opened up new avenues for studying the role of symmetry in dark matter and black holes. To further advance our understanding, this Special Issue aims to explore the intricate interplay between symmetry and these fascinating cosmic entities. Through the contributions of leading experts in the field, with this Special Issue, we hope to shed light on the crucial role of symmetry in the understanding of dark matter and black holes. By elucidating the symmetries underlying these phenomena, this research will not only deepen our knowledge but also pave the way for future breakthroughs in unraveling the mysteries of the universe at both macroscopic and microscopic scales.

This Special Issue will accept contributions in the following areas:

• Symmetry in Dark Matter: Manuscripts focusing on the role of symmetry in dark matter will be welcomed. This includes investigations into the symmetries exhibited by dark matter candidates, such as WIMPs (Weakly Interacting Massive Particles), axions, and sterile neutrinos. Contributions can explore how these symmetries influence the formation, distribution, and interactions of dark matter in the universe. Additionally, studies on the implications of discrete or continuous symmetries on dark matter detection strategies, experimental searches, and model building are encouraged;
• Symmetry in Black Holes: Manuscripts that examine the symmetries associated with black holes are invited. This comprises research on the symmetrical properties of black hole solutions in various gravitational theories, including general relativity and its extensions. Contributions can explore the symmetries of black hole spacetimes, such as spherical, axial, or stationary symmetries, and their consequences for the dynamics, thermodynamics, and astrophysical signatures of black holes. Investigations into the role of symmetries in black hole evaporation, information paradox, and the existence of exotic solutions like black hole hair are also of interest;
• Experimental Observations and Symmetry: Manuscripts discussing the impact of experimental observations on understanding symmetry in dark matter and black holes will be considered. This includes contributions on cutting-edge observational techniques, such as gravitational wave measurements, black hole imaging, and cosmological surveys, and how these observations provide insights into the symmetries governing dark matter and black hole physics. Additionally, studies that showcase the interplay between theoretical symmetry considerations and experimental results are encouraged;
• Theoretical Frameworks and Symmetry: Manuscripts presenting theoretical frameworks that incorporate symmetry principles to explain dark matter and black hole properties are encouraged. This includes contributions on symmetry-breaking mechanisms, gauge theories, supersymmetry, and other theoretical frameworks that elucidate the role of symmetry in these cosmic phenomena. Investigations into the connection between symmetries, holography, and quantum information theory in the context of dark matter and black holes are also welcomed.
