Discovery of a young, 267 millisecond pulsar in the supernova remnant W44This paper reports the discovery of a 267 msec pulsar, PSR 1853 + 01, in the SNR W44 (G34.7 - 0.4), located south of the W44, well within its radio shell and at the outher edge of the X-ray emission region which fills the SNR interior. The PSR 1853 + 01 is separated only 20 arcmin from the PSR 1854 + 00 pulsar discovered by Mohanty (1983). Results of timing observatons of PSR 1853 + 01 are presented, and a possible relationship between the two objects is examined. It is suggested that the two pulsars may have a common origin in a binary system disrupted by the explosion that produced W44.
