Производитель: "Неизвестный" In 2004, for the first time in the history of very-high energy gamma-ray astronomy, diffuse emission of gamma-rays from a pulsar wind nebula, was observed from the supernova remnant, MSH 15-52, by the H. E. S. S (High Energy Stereoscopic System). The supernova remnant (SNR), MSH 15-52, consisting of a PWN which is powered by a 150 millisecond relatively young and energetic pulsar, B1509-58, was observed with H. E. S. S. during 23 nights. The likelihood of the pulsar periodicity being propagated into the PWN emission was investigated, by searching for periodicity of VHE gamma-ray emission at and near the radio period from the entire composite supernova remnant. Fourier analysis techniques were employed for searching for a pulsed signal. This was done via the well-known universally most powerful (UMP) test, the Rayleigh test, and the H-test. No pulsed emission could be seen using the Rayleigh test and the H-test. The Eadie combination method of Rayleigh test results also showed no evidence of...
