      abstract     = {The conformational and dynamical properties of active
                      polymers in solution are determined by the nature of the
                      activity. Here, the behavior of polymers with
                      self-propelled, active Brownian particle-type monomers
                      differs qualitatively from that of polymers with monomers
                      driven externally by colored-noise forces. We present
                      simulation and theoretical results for polymers in solution
                      in the presence of external active noise. In simulations, a
                      semiflexible bead-spring chain is considered, in analytical
                      calculations, a continuous linear wormlike chain. Activity
                      is taken into account by independent monomer or site
                      velocities, with orientations changing in a diffusive
                      manner. In simulations, hydrodynamic interactions (HIs) are
                      taken into account by the Rotne-Prager-Yamakawa tensor or by
                      an implementation of the active polymer in the
                      multiparticle-collision-dynamics approach for fluids. To
                      arrive at an analytical solution, the preaveraged Oseen
                      tensor is employed. The active process implies a dependence
                      of the stationary-state properties on HIs via the polymer
                      relaxation times. With increasing activity, HIs lead to an
                      enhanced swelling of flexible polymers, and the
                      conformational properties differ substantially from those of
                      polymers with self-propelled monomers in the presence of
                      HIs, or free-draining polymers. The polymer mean-square
                      displacement is enhanced by HIs. Over a wide range of
                      timescales, hydrodynamics leads to a subdiffusive regime of
                      the site mean-square displacement for flexible active
                      polymers, with an exponent of 5/7, larger than that of the
                      Rouse (1/2) and Zimm (2/3) models of passive polymers.},
