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