Query: Dwarf Galaxy $\gamma$-excess and 3.55 keV X-ray Line In A Nonthermal
  Dark Matter Model   Recent data from Reticulum II (RetII) require the energy range of the
FermiLAT $\gamma$-excess to be $\sim$ $2-10$ GeV. We adjust our unified
nonthermal Dark Matter (DM) model to accommodate this. We have two extra
scalars beyond the Standard Model to also explain 3.55 keV X-ray line. Now the
mass of the heavier of them has to be increased to lie around 250 GeV, while
that of the lighter one remains at 7.1 keV. This requires a new seed mechanism
for the $\gamma$-excess and new Boltzmann equations for the generation of the
DM relic density. All concerned data for RetII and the X-ray line can now be
fitted well and consistency with other indirect limits attained.
