In a...The data base was used to study the glitch activity among the pulsar population, finding that it peaks for pulsars with a characteristic age τ c ∼ 10 kyr and decreases for longer values of τ c, disappearing for objects with τ c > 20 Myr. The glitch activity is also smaller in the very young pulsars (τ c ≲ 1 kyr). The cumulative effect ...2.1 PSR J0627+0706. With a characteristic age of only 250 kyr, PSR J0627+0706 is by far the most energetic object in this sample. This object displays a prominent interpulse, suggesting an orthogonal rotator. It also has significant timing noise, which is typical of young pulsars. This is the reason for the large reduced χ 2 of its solution.The discovery of a large ~5° teraelectronvolt emission around the ≳ 100-kyr-old pulsars Geminga and PSR B0656+14 triggered a new understanding of the ... the 11-kyr-old Vela X shows a compact ...3.1 PSR B0154+61 (J0157+6212, τ=200 kyr) Although data on PSR B0154+61 have been collected at Jodrell Bank for more than 10 yr since MJD 46866, this pulsar suffered its first observed glitch near MJD 48504. The glitch was quite small with the size of the frequency jump equal to 2.46 × 10 −9. The frequency and timing residuals are shown in lower and …Kyr's Kaleidoscope. 34 likes.

Welcome to my Kaleidoscope.We report on the X-ray emission properties of the pulsar PSR J1849$-$0001 and its wind nebula (PWN), as measured by Chandra, XMM-Newton, NICER, Swift, and NuSTAR. In the X-ray data, we detected the 38-ms pulsations of the pulsar up to $\\sim$60 keV with high significance. Additionally, we found that the pulsar's on-pulse spectral energy distribution displays significant curvature, peaking at ...around PSR J1906+0746. If PSR J1906+0746 were the prod-uct of an SN explosion of massive core, then it would be most likely to produce a detectable SNR born in such a short time (˘113 kyr) and a distance from 5 kpc to 10 kpc. DNSs are not disrupted in the case of two SNs, this places strict limits on the nature of these systems' second SN ...PSR J1906+0722 is a young, energetic, isolated pulsar, with a spin frequency of 8.9 Hz, a characteristic age of 49 kyr, and spin-down power 1.0× {10} 36 erg s-1.

A few more HAWC-detected sources have been suggested to be ...The thresholds are 10 c s −1 for PSR J0537−6910, 4.5 c s −1 for PSR J1412+7922, and 5 c s −1 for PSR J1849−0001, and they are the same as previously used in Ho et al. for PSR J0537−6910 and in Bogdanov et al. for PSR J1412+7922 and PSR J1849−0001. Using these filtering criteria, we obtain clean data for pulse timing analysis.We report the discovery and follow-up timing observations of two young energetic radio pulsars.

The characteristic age of PSR J1734-3333 estimated from its current spin down rate implies that it is a young pulsar (τc = 8.1 kyr). However, the time derivative of its spin-down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.
