  Measuring the $M$th-order intensity correlation function of light emitted by
two statistically independent thermal light sources may display N00N-like
interferences of arbitrary order $N = M/2$. We show that via a particular
choice of detector positions one can isolate $M$-photon quantum paths where
either all $M$ photons are emitted from the same source or $M/2$ photons are
collectively emitted by both sources. The latter superposition displays
N00N-like oscillations with $N = M/2$ which may serve, e.g., in astronomy, for
imaging two distant thermal sources with $M/2$-fold increased resolution. We
also discuss slightly modified detection schemes improving the visibility of
the N00N-like interference pattern and present measurements verifying the
theoretical predictions.
