      abstract     = {The intramolecular dynamics of flexible and semiflexible
                      polymers in response to active noise is studied
                      theoretically. The active noise may either originate from
                      interactions of a passive polymer with a bath of active
                      Brownian particles or the polymer itself is comprised of
                      active Brownian particles. We describe the polymer by the
                      continuous Gaussian semiflexible-polymer model, taking into
                      account the finite polymer extensibility. Our analytical
                      calculations predict a strong dependence of the polymer
                      dynamics on the activity. In particular, active semiflexible
                      polymers exhibit a crossover from a bending
                      elasticity-dominated dynamics at weak activity to that of
                      flexible polymers at strong activity. The end-to-end vector
                      correlation function decays exponentially for times longer
                      than the longest polymer relaxation time. Thereby, the
                      polymer relaxation determines the decay of the correlation
                      function for long and flexible polymers. For shorter and
                      stiffer polymers, the relaxation behavior of individual
                      active Brownian particles dominates the decay above a
                      certain activity. The diffusive dynamics of a polymer is
                      substantially enhanced by the activity. Three regimes can be
                      identified in the mean square displacement for sufficiently
                      strong activities: an activity-induced ballistic regime at
                      short times, followed by a Rouse-type polymer-specific
                      regime for any polymer stiffness, and free diffusion at long
                      times, again determined by the activity.},
