Query: Maximal curves from subcovers of the GK-curve   For every $q=n^3$ with $n$ a prime power greater than $2$, the GK-curve is an
$\mathbb F_{q^2}$-maximal curve that is not $\mathbb F_{q^2}$-covered by the
Hermitian curve. In this paper some Galois subcovers of the GK curve are
investigated. We describe explicit equations for some families of quotients of
the GK-curve. New values in the spectrum of genera of $\mathbb F_{q^2}$-maximal
curves are obtained. Finally, infinitely many further examples of maximal
curves that cannot be Galois covered by the Hermitian curve are provided.
