英文摘要Pulse arrival time measurements over 14 yr with the Nanshan 25-m and Parkes 64-m radio telescopes have been used to determine the average profile and timing properties for PSR J1757-2421 (B1754-24). Analysis of the radio profile data shows a large variation of spectral index across the profile and an unusual increase in component separation with increasing frequency. The timing observations show that PSR B1754-24 underwent a large glitch with a fractional increase in spin frequency of Delta v(g)/v similar to 7.8 x 10(-6) in 2011 May. At the time of the glitch, there was a large permanent jump in the rotational frequency accompanied by two exponential recovery terms with time-scales of 15(6) and 97(15) d, respectively.
