Pulsar timing arrays (PTAs) are used to search for long-wavelengthgravitational waves (GWs) by monitoring a set of spin-stable millisecondpulsars. Most theoretical analyses assume that the relevant GW sources are muchmore distant from Earth than the pulsars comprising the array. Unlike ground-or solar system-based GW detectors, PTAs might well contain embedded GWsources. We derive the PTA response from sources at any distance, with aspecific focus on GW bursts with memory (BWMs). We consider supernovae andcompact binary mergers as potential Galactic BWM sources and evaluate thesignature for an array with pulsars in globular clusters or in the Galacticcenter. Understanding the response of PTAs to nearby sources of BWM is a steptowards investigating other more complex Galactic sources.
