Observations of 14 pulsar glitches.

Abstract (from CDS):

About 76 glitches in 25 pulsars have been reported to date. Most glitches are `giant', with fractional increases of frequency Δν00 ∼ 10–6. 25 glitches were analysed and presented by Shemar and Lyne, who detected them mainly at Jodrell Bank during the monitoring of a sample of 279 pulsars in a regular timing programme up to MJD 49500. This paper is a continuation of their work up to MJD 50500. We present the detection and analysis of a further 14 glitches in 9 pulsars, 6 of which have glitched for the first time since monitoring had started. Eleven of these glitches are small (Δν00∼ 10–9) and below the completeness threshold of Shemar & Lyne. We report a giant glitch in PSR B1930+22, the second largest reported hitherto, with a Δν00= 4.5x10–6. We also report four recent glitches in PSR B1737-30 which continues to exhibit frequent glitches. Few of these pulsars show any recovery after the glitch.
