Query: On absolute moments of characteristic polynomials of a certain class of
  complex random matrices   Integer moments of the spectral determinant $|\det(zI-W)|^2$ of complex
random matrices $W$ are obtained in terms of the characteristic polynomial of
the Hermitian matrix $WW^*$ for the class of matrices $W=AU$ where $A$ is a
given matrix and $U$ is random unitary. This work is motivated by studies of
complex eigenvalues of random matrices and potential applications of the
obtained results in this context are discussed.
