Query: Constraining the neutrino emission of gravitationally lensed
  Flat-Spectrum Radio Quasars with ANTARES data   This paper proposes to exploit gravitational lensing effects to improve the
sensitivity of neutrino telescopes to the intrinsic neutrino emission of
distant blazar populations. This strategy is illustrated with a search for
cosmic neutrinos in the direction of four distant and gravitationally lensed
Flat-Spectrum Radio Quasars. The magnification factor is estimated for each
system assuming a singular isothermal profile for the lens. Based on data
collected from 2007 to 2012 by the ANTARES neutrino telescope, the strongest
constraint is obtained from the lensed quasar B0218+357, providing a limit on
the total neutrino luminosity of this source of $1.08\times
10^{46}\,\mathrm{erg}\,\mathrm{s}^{-1}$. This limit is about one order of
magnitude lower than those previously obtained in the ANTARES standard point
source searches with non-lensed Flat-Spectrum Radio Quasars.
