Abstract
We report on the analysis of archival ASCA, ROSAT and BeppoSAX data of PSR B1055-52, PSR B0656+14 and Geminga, performed in order to investigate the r eality of the putative similar to 10-20 arcmin wide X-ray pulsar-wind nebul ae recently proposed to exist around these pulsars. In all these cases, the ROSAT and/or BeppoSAX data show that the diffuse and clumpy X-ray nebulae found by ASCA can be resolved in the contribution of unidentified point sou rces, unlikely related to the pulsars.
