NuSTAR analysis of the PWN and SNR in G21.5-0.9
Abstract
Beginning in July 2012, NuSTAR observed G21.5-0.9, a Crab-like Pulsar Wind Nebula (PWN) with centrally-peaked synchrotron emission located in the Galactic Plane. Though the object is well-studied in the radio, soft X-ray, and TeV energy bands, NuSTAR is the first focusing telescope to observe G21.5-0.9 above 10 keV. We present our analysis of the PWN itself, specifically the detection of a spectral break at 9.7 keV and the energy-dependant size of the PWN. Spatially-resolved hard X-ray images reveal the non-thermal emission along the eastern and Northern rim of the supernova (SN) shell. The implications for SN and PWN physics are discussed.
