Abstract
In this paper we report unusual glitches in two young pulsars, PSR J1825-0935 (B1822-09) and PSR J1835-1106. For PSR J1825-0935, a slow glitch characterized by a temporary decrease in the slow-down rate occurred between 2000 December 31 and 2001 December 6. This event resulted in a permanent increase in frequency with fractional size Deltanu/nu similar to 31.2( 2) x 10(-9); however, little effect remained in the slow-down rate. The glitch in PSR J1835-1106 occurred abruptly in 2001 November (MJD 52 220 +/- 3) with Deltanu/nu similar to 14.6(4) x 10(-9) and little or no change in the slow-down rate. A significant change in nu apparently occurred at the glitch with nu having opposite sign for the pre- and post-glitch data.
