The interaction between boson fields and fermions may lead to parametric production or Schwinger pair production of fermions, with efficiencies significantly exceeding those of perturbative decay processes. Additionally, the spatial gradients of scalar clouds and the electric components of vector clouds can accelerate fermions, resulting in observable fluxes. This study considers both Standard Model neutrinos and dark sector fermions, which could contribute to boosted dark matter. Energy loss due to fermion emissions can potentially quench the exponential growth of the cloud, leading to a saturated state. This dynamic provides a framework for establishing limits on boson-neutrino interactions, previously constrained by neutrino self-interaction considerations. In the saturation phase, boson clouds have the capacity to accelerate fermions to TeV energies, producing fluxes that surpass those from atmospheric neutrinos near black holes. These fluxes open new avenues for observations through high-energy neutrino detectors like IceCube, as well as through dark matter direct detection efforts focused on targeted black holes. 000627756 536__ $$0G:(DE-HGF)POF4-611$$a611 - Fundamental Particles and Forces (POF4-611)$$cPOF4-611$$fPOF IV$$x0 000627756 536__ $$0G:(EU-Grant)101052587$$aGravitas - Black holes: gravitational engines of discovery (101052587)$$c101052587$$fERC-2021-ADG$$x1 000627756 536__ $$0G:(GEPRIS)390833306$$aDFG project G:(GEPRIS)390833306 - EXC 2121: Quantum Universe (390833306)$$c390833306$$x2 000627756 588__ $$aDataset connected to CrossRef, Journals: bib-pubdb1.desy.de 000627756 650_7 $$2INSPIRE$$ascale: Planck 000627756 650_7 $$2INSPIRE$$aneutrino: atmosphere 000627756 650_7 $$2INSPIRE$$aneutrino: production 000627756 650_7 $$2INSPIRE$$aneutrino: particle source 000627756 650_7 $$2INSPIRE$$ascale: TeV 000627756 650_7 $$2INSPIRE$$afield theory: scalar 000627756 650_7 $$2INSPIRE$$ablack hole 000627756 650_7 $$2INSPIRE$$asuperradiance 000627756 650_7 $$2INSPIRE$$asaturation 000627756 650_7 $$2INSPIRE$$atrigger 000627756 650_7 $$2INSPIRE$$atransducer 000627756 650_7 $$2INSPIRE$$aquenching 000627756 650_7 $$2INSPIRE$$aparametric 000627756 650_7 $$2INSPIRE$$acloud 000627756 650_7 $$2INSPIRE$$aboson: mass 000627756 650_7 $$2INSPIRE$$aenergy: yield 000627756 650_7 $$2INSPIRE$$aneutrino: coupling 000627756 650_7 $$2INSPIRE$$aacceleration 000627756 650_7 $$2INSPIRE$$aflux 000627756 650_7 $$2autogen$$aastrophysical black holes 000627756 650_7 $$2autogen$$agravity 000627756 650_7 $$2autogen$$aneutrino astronomy 000627756 650_7 $$2autogen$$aparticle acceleration 000627756 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000627756 7001_ $$0P:(DE-HGF)0$$aXue, Xiao$$b1 000627756 7001_ $$aCardoso, Vitor$$b2 000627756 773__ $$0PERI:(DE-600)2104147-7$$a10.1088/1475-7516/2025/02/035$$gVol. 2025, no. 02, p. 035 -$$n02$$p035 $$tJournal of cosmology and astroparticle physics$$v02$$x1475-7508$$y2025 000627756 7870_ $$0PUBDB-2023-04449$$aChen, Yifan et.al.$$d2023$$iIsParent$$rDESY-23-109 ; arXiv:2308.00741$$tBlack Holes as Neutrino Factories 000627756 8564_ $$uhttps://bib-pubdb1.desy.de/record/627756/files/Chen_2025_J._Cosmol._Astropart._Phys._2025_035.pdf$$yOpenAccess 000627756 8564_ $$uhttps://bib-pubdb1.desy.de/record/627756/files/Chen_2025_J._Cosmol._Astropart._Phys._2025_035.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000627756 909CO $$ooai:bib-pubdb1.desy.de:627756$$pdnbdelivery$$pec_fundedresources$$pVDB$$pdriver$$popen_access$$popenaire 000627756 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-HGF)0$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000627756 9131_ $$0G:(DE-HGF)POF4-611$$1G:(DE-HGF)POF4-610$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMatter and the Universe$$vFundamental Particles and Forces$$x0 000627756 9141_ $$y2025 000627756 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2025-01-02 000627756 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000627756 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bJ COSMOL ASTROPART P : 2022$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000627756 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ COSMOL ASTROPART P : 2022$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium$$d2025-01-02$$wger 000627756 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2025-01-02 000627756 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2025-01-02 000627756 9201_ $$0I:(DE-H253)UNI_TH-20120731$$kUNI/TH$$lUni Hamburg / Theorie$$x0 000627756 980__ $$ajournal 000627756 980__ $$aVDB 000627756 980__ $$aUNRESTRICTED 000627756 980__ $$aI:(DE-H253)UNI_TH-20120731 000627756 9801_ $$aFullTexts
