We investigate the possibility of the high-energy particles with this new spectrum injected in pulsar wind nebulae (PWNe) from the terminate shock based on the study of multiwavelength emission from PWNe.} {The dynamics of a supernova remnant (SNR) and multiband nonthermal emission from the PWN inside the remnant are investigated using a dynamical model with electrons/positrons injected with the new spectrum. In this model, the dynamical and radiative evolution of a pulsar wind nebula in a non-radiative supernova remnant can be self-consistently described.} {This model is applied to the three composite SNRs, G0.9+0.1, MSH 15-52, G338.3-0.0, and the multiband observed emission from the three PWNe can be well reproduced.} {Our studies on the three remnant provide evidence for the new spectrum of the particles, which are accelerated by the terminate shock, injected into a PWN.", "revisions": [ { "version": "v1", "updated": "2010-03-08T15:42:01.000Z" } ], "analyses": { "keywords": [ "pulsar wind nebula", "multiband emission", "injection spectrum", "terminate shock", "supernova remnant" ], "tags": [ "journal article" ], "publication": { "doi": "10.1051/0004-6361/200913615", "journal": "Astronomy and Astrophysics", "year": 2010, "month": "Jun", "volume": 515 }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "inspire": 848002, "adsabs": "2010A&A...515A..20F" } } }
