It introduces how to model asymmetric mass-ratio binaries evolving while immersed in an environment constituted by an ultralight (complex) scalar field using techniques of black hole perturbation theory, and focusing on the simpler example of a spherically symmetric cloud around a non-rotating black hole. A Mathematica notebook with the derivation and solver of the equations of motion of the system is also provided.","url_abs":"https://arxiv.org/abs/2412.08711v1","url_pdf":"https://arxiv.org/pdf/2412.08711v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"new-horizons-for-psi-extreme-mass-ratio","repo_url":"https://github.com/franciscoduque/emribosons","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
