Query: Absorption and scattering of a noncommutative black hole   In this paper we focus on the partial wave method with the aim of exploring
the scattering of massless scalar waves due to the noncommutative Schwarzschild
black hole via Lorentzian smeared mass distribution. We determine the phase
shift analytically in low-frequency limit and we show that the scattering and
absorption cross section is modified. Specially, we show that in the
low-frequency limit the scattering/absorption cross section has its value
decreased when we increase the value of the non-commutativity parameter. In
addition, we have confirmed this result by solving the problem numerically for
arbitrary frequencies. Such modifications found for the scattering and
absorption cross section present similarities with the Reissner-Nordstr\"{o}m
black hole.
