ABSTRACT The observation of quasars at high redshifts presents a mystery in the theory black hole formation. In order to source such objects, one often relies on presence heavy seeds ($M \approx 10^{4-6}{\rm M}_{\odot }$) place early times. Unfortunately, formation these are difficult realize within standard astrophysical context. Here, we investigate whether superconducting cosmic string loops can sufficiently strong overdensities universe address this mystery. We review set direct collapse conditions under which primordial gas cloud will undergo monolithic into massive (forming with mass $M_{\rm BH} 10^5{\rm }$ z ≈ 300 our scenario), and systematically show how satisfy regions Gμ − I parameter space.
