  We present a major update on our investigations of SU(2) gauge theory with
one Dirac flavor in the adjoint representation on the lattice. In particular we
consider larger volumes, as well as four different values of the gauge
coupling. We provide results for the spectrum including gluonic, fermionic, and
hybrid observables, Polyakov loops, and the anomalous dimension of the
fermionic condensate from the Dirac mode number. These data confirm that the
theory is close to the lower boundary of the conformal window for adjoint
fermions. Our investigations provide important insights regarding the
realization of different infrared scenarios that have been conjectured for this
theory.
