Accelerated observers and horizons at the Planck scale
Abstract: We extend the concept of accelerated horizons to the framework of deformed relativistic kinematics at the Planck scale. We show that the non-trivial effects due to symmetry deformation lead to a blurring of the horizon which manifests in a finite redshift for signals sent by an observer which approaches the horizon.
