Resumen:
Abstract We report hard X-ray emission of the non-thermal supernova remnant G337.2+0.1. The source presents centrally filled and diffuse X-ray emission. A spectral study confirms that the column density of the central part of the object is about NH ¡­ 5.9(¡¾1.5) ¡¿ 1022 cm−2 and its X-ray spectrum is well represented by a single power-law with a photon index ¥Ã = 0.96 ¡¾ 0.56. Detailed spectral analysis  indicates that the outer region is highly absorbed and quite softer than the inner region. Characteristics already observed in other well-known X-ray plerions. Based on the gathered information, we confirm the SNR nature of G337.2+0.1,  and suggest that the central region of the source is a pulsar wind nebula (PWN), originated by an energetic though yet undetected pulsar.
