The observation of a single sub-solar mass black hole would establish the existence of primordial black holes and a possible component of dark matter. We search the $\\sim 164$ days of public LIGO data from 2015-2017 when LIGO-Hanford and LIGO-Livingston were simultaneously observing. We find no significant candidate gravitational-wave signals. Using this non-detection, we place a $90\\%$ upper limit on the rate of $30-0.01~\\mathrm{M}_{\\odot}$ and $30-0.1~\\mathrm{M}_{\\odot}$ mergers at $<1.2\\times10^{6}$ and $<1.6\\times10^{4} ~\\mathrm{Gpc}^{-3} \\mathrm{yr}^{-1}$, respectively. If we consider binary formation through direct gravitational-wave braking, this kind of merger would be exceedingly rare if only the lighter black hole were primordial in origin ($<10^{-4}~\\mathrm{Gpc}^{-3}\\mathrm{yr}^{-1}$). If both black holes are primordial in origin, we constrain the contribution of $1 (0.1)~\\mathrm{M}_{\\odot}$ black holes to dark matter to $< 0.3 (3)\\%$.","url_abs":"https://arxiv.org/abs/2007.03583v1","url_pdf":"https://arxiv.org/pdf/2007.03583v1.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":"search-for-gravitational-waves-from-high-mass","repo_url":"https://github.com/gwastro/stellar-pbh-search","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
