Wielebinski | | Subject: | astro-ph | | Affiliation: | Indian Institute of Astrophysics, India, National Centre for Radio Astrophysics, India, Arecibo Observatory, USA | | Abstract: | To study the structure of emission beam, we have analysed the single pulse data of PSR B0329+-54 at 325 and 606 MHz. In order to unambiguously detect the weak emission components, we have developed a new data analysis technique, which we term ``window-thresholding’’. By applying this technique to the data, we have detected three new emission components, and also confirmed the presence of a component which was proposed earlier. Hence our analysis indicates that PSR B0329+-54 has nine components, which is among the highest of all the known pulsars. The symmetric distribution of pulse components about the pulse centre, indicates that the emission beam is conal. | | Source: | arXiv, astro-ph/9911029 | | Services: | Forum | Review | PDF | Favorites | |
