Query: Using Pantheon and DES supernova, baryon acoustic oscillation, and
  Hubble parameter data to constrain the Hubble constant, dark energy dynamics,
  and spatial curvature   We use Pantheon Type Ia supernova (SN Ia) apparent magnitude, DES-3yr binned
SN Ia apparent magnitude, Hubble parameter, and baryon acoustic oscillation
measurements to constrain six spatially flat and non-flat cosmological models.
These sets of data provide mutually consistent cosmological constraints in the
six cosmological models we study. A joint analysis of these data sets provides
model-independent estimates of the Hubble constant, $H_0=68.8\pm1.8\ \rm{km \
s^{-1} \ Mpc^{-1}}$, and the non-relativistic matter density parameter,
$\Omega_{\rm m_0}=0.294\pm0.020$. Although the joint constraints prefer mild
dark energy dynamics and a little spatial curvature, they do not rule out dark
energy being a cosmological constant and flat spatial hypersurfaces. We also
add quasar angular size and H II starburst galaxy measurements to the combined
data set and find more restrictive constraints.
