Abstract. PSR J0537 −--6910 is a young, energetic, rotation-powered X-ray pulsar with a spin period of 16 ms located in the Large Magellanic Cloud. We have searched for previously undetected radio pulsations (both giant and standard) from this pulsar in a 12-hour observation taken at 1400 MHz with the Parkes 64-m radio telescope.Here's how to get those travel vibes without leaving town.

We conclude that PSR J0726-2612 is indeed an example of a young INS, one that started with a magnetic field strength on the low end of those inferred for the INSs, and that, therefore, decayed by a relatively …B s = 1. 0 × 10 12 G, a nd a characteristic age of 8.9 kyr.

Remaining undetected in dedicated radio follow-up observations ...However,no x-ray photons have been observed near the J1906+0746 radio position.[4]This also confirmed that there is no SNR around PSR J1906+0746. If PSR J1906+0746 were the product 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.01:00:09 UTC. Now observing the Crab pulsar PSR B0531+21 with the 42ft telescope. Rotation period: 33.4 ms Age: 1 kYr Distance: 2.0 kpc. 23 Jan 2022PSR J0205+6449 is a 65 ms rotation-powered pulsar residing in the center of the supernova remnant 3C 58. The pulsar was discovered in a 2002 Chandra X-ray Observatory observation of the source (Murray et al. 2002) and subsequently detected as a radio pulsar (Camilo et al. 2002).It is one of the most energetic pulsars in the Galaxy, …The characteristic age of PSR J1734−3333 estimated from its current spin down rate implies that it is a young pulsar (τ c = 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.Alex Zepka. We discuss PSR J1740+1000, one of five pulsars recently discovered in a search of 470 square degrees at 430 MHz during the upgrade of the 305-m Arecibo telescope. The period of 154 ms ...Because no glitches were found in the latest 7.1 yr of timing data, this extends the time without a detected glitch for PSR B1509−58 to 28.4 yr. While the youngest pulsars (τ c < 2 kyr) tend to have smaller and fewer glitches than somewhat older pulsars (τ c ∼ 5–10 kyr), PSR B1509−58 is extreme in its lack of glitches.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.The pulsar's spin-down rate implies a rotation-powered luminosity E-dot = 1.2x10{sup 38} erg s{sup -1}, a surface dipole magnetic field strength B{sub s} = 1.0 x 10{sup 12} G, and a characteristic age of 8.9 kyr. PSR J2022+3842 is thus the second-most energetic Galactic pulsar known, after the Crab pulsar, as well as the most rapidly rotating ...Abstract. We describe a sensitive targeted search campaign at Parkes to find faint young radio pulsars using the center beam of the 20-cm multi-beam receiver. The high …The abbreviation kyr means "thousand years". Kyr was formerly common in some English language works, especially in geology and astronomy, for the unit of 1,000 years or millennium. The "k" is the unit prefix for kilo- or thousand with the suffix "yr" simply an abbreviation for "year". Occasionally, the "k" is shown in upper case, as in "100 Kyr ...The characteristic age of PSR J1734−3333 estimated from its current spin down rate implies that it is a young pulsar ( τ c = 8.1 kyr). However, the time derivative of its spin-down rate differs ...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 ...We report on the setup and initial discoveries of the Northern High Time Resolution Universe survey for pulsars and fast transients, the first major pulsar survey conducted with the 100-m Effelsberg radio telescope and the first in 20 years to observe the whole northern sky at high radio frequencies. Using a newly developed 7-beam receiver system combined with a state-of-the-art polyphase ...The second pulsar, PSR J1814-1744, has P=3.975 s and P=7.4×10-13. These parameters imply τ c =85 kyr, and B=5.5×10 13 G, the largest of any known radio pulsar. Both PSR J1119-6127 and PSR J1814-1744 show apparently normal radio emission in a regime of magnetic field strength where some models predict that no emission should occur.The age of PSR J1814[1744, if P > P and n \ 3, Especially noteworthy is the proximity of PSR 0 is 85 kyr. It is unlikely that any associated supernova J1814[1744 to the cluster of AXPs and SGRs at the upper remnant would still be observable, and indeed there is none right corner of Figure 3.Dec 9, 2021 · For the pulsar PSR J1734-3333, both the estimated SNR age (23 kyr) [35] and proper motion age (45-100 kyr) [94] are much older than its characteristic age (8.1 kyr), which might hint at the fact ...About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...Particularly interesting is the association of the pulsar PSR J0538+2817 with the young supernova remnant S147 and an age of only 30±4 kyr (Kramer et al. 2003; Dinçel et al. 2015), because the ...acteristic age τ ≡P/2P˙ ∼17 kyr, PSR J2021+3651 is still energetic, with E˙ ∼3.4 ×1036 erg s−1.
