Query: Lee-Yang-inspired energy-density functional including contributions from
  $p$-wave scattering   The ELYO functional proposed in [M. Grasso, D. Lacroix, and C. J. Yang, Phys.
Rev. C \textbf{95}, 054327 (2017)] belongs to the family of energy-density
functionals (EDFs) inspired by effective-field theories (EFTs) and constrained
by \textit{ab--initio} pseudo-data. We present here an extension of this EDF
which also accounts for the first $p$-wave term appearing in the low-density
expansion from which it derives. It is shown that this enrichment of the ansatz
on which the functional is based leads to a significant improvement of the
description of neutronic systems, especially in regimes besides the
pseudo--data set employed to adjust the parameters. As an illustrative
application, the mass-radius relation of neutron stars is considered. In
contrast to its initial version, the new functional predicts values which are
qualitatively consistent with recent observations.
