Query: Double ramification cycles and the $n$-point function for the moduli
  space of curves   In this paper, using the formula for the integrals of the $\psi$-classes over
the double ramification cycles found by S. Shadrin, L. Spitz, D. Zvonkine and
the author, we derive a new explicit formula for the $n$-point function of the
intersection numbers on the moduli space of curves.
