Finite Energy of Black Holes in Massive Gravity
  In GR the static gravitational potential of a self-gravitating body goes as
1/r at large distances and any slower decrease leads to infinity energy. We
show that in a class of four-dimensional massive gravity theories there exists
spherically symmetric solutions with finite total energy, featuring an
asymptotic behavior slower than 1/r and generically of the form $r^\gamma$.
This suggests that configurations with nonstandard asymptotics may well turn
out to be physical. The effect is due to an extra field coupled only
gravitationally, which allows for modifications of the static potential
generated by matter, while counterbalancing the apparently infinite energy
budget.
