We report on diffuse X-ray emission associated with the
nearby solitary millisecond pulsar PSR J2124-3358 detected with XMM-Newton and Chandra.
The emission extends from the pulsar to the northwest by ~ arcmin.
The spectrum of the nebular emission can be modeled with a power-law of
photon index
, in line with the emission originating from
accelerated particles in the post shock flow. For PSR J0437-4715,
PSR J0030+0451 and PSR J1024-0719, which all have spin parameters
comparable to that of PSR J2124-3358, no diffuse emission is detected down
to a
limiting flux of ~
erg s-1 cm-2.
