Lin et al., Phys. Rev. Lett 130, 111002 (2023) and Y.-H. Lin et al., Phys. Rev. D 108, 083013 (2023)]. In this Letter, we extend this concept and evaluate the present-day diffuse flux of SN$\\nu$ BDM originated from all galaxies at higher redshifts. We show that by considering this diffuse BDM (DBDM) component, the best sensitivity on the product of the energy-independent DM-$\\nu$ and DM-electron cross sections, $\\sqrt{\\sigma_{\\chi\\nu}\\sigma_{\\chi e}}\\simeq \\mathcal{O}(10^{-37})$ cm$^2$ for sub-MeV DM, can be obtained with large-size neutrino experiments such as Super-Kamiokande or Hyper-Kamiokande, surpassing the estimated SN$\\nu$ BDM bound from SN1987a. We also examine the impact due to the presence of DM spikes around the supermassive black holes in galaxies on SN$\\nu$ BDM and DBDM. Our results suggest that both the DBDM and the SN$\\nu$ BDM probes are robust to the uncertain properties of DM spikes, unless the next Galactic SN happens to occur at a location extremely close to or right behind the Galactic Center along the SN line of sight.","url_abs":"https://arxiv.org/abs/2404.08528v2","url_pdf":"https://arxiv.org/pdf/2404.08528v2.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":"echoes-of-darkness-supernova-neutrino-boosted","repo_url":"https://github.com/yenhsunlin/dukes","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}
