A Unified picture of Dark Matter and Dark Energy from Invisible QCD
  It has been shown in a companion paper that the late time acceleration of the
universe can be accounted for by an extension of the QCD color to a $SU(3)$
invisible sector (IQCD). In this work we discuss a unified framework such the
scale of dark chiral-breaking dictates both the accelerated expansion of the
universe, and the origin of dark matter. We find that the strong and
gravitational dynamics of dark quarks and gluons evolve to eventually form
exotic dark stars. We discuss the dynamical complexity of these dark compact
objects in light of dark big bang nucleosynthesis. We argue how IQCD favors a
halo composed of very compact dark neutron stars, strange/quark stars and black
holes, with masses $M_{MACHO}< 10^{-7}M_{\odot}$. This avoids limit from MACHO
and EROS collaborations as well as limit from clusters. We also discuss
possible phenomenological implications in dark matter searches. We argue that
dark supernovae and dark binaries can emit very peculiar gravitational waves
signal testable by the LIGO/VIRGO collaboration and future projects dedicated
to these aspects.
