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 ...c = 42:9 kyr) rotation-powered pulsar (Gotthelf et al.2011;Kuiper & Hermsen 2015).

PSR J1412+7922 and PSR J1849 0001 are only seen to be pulsed in X-rays, the timing models presented here will enable LIGO/Virgo to search for GWs from these two …Bs = 1.0×1012 G, and a characteristic age of 8.9 kyr. PSR J2022+3842 is thus the second-most ener-getic Galactic pulsar known, after the Crab, as well as the most rapidly-rotating young, radio-bright pulsar known. The radio pulsations are highly dispersed and broadened by interstellar scattering, and we find that a large (δf/f ≈ 1.9 × 10−6) spin glitch must …We have obtained a deep (670 ks) CXO ACIS image of the remarkable pulsar wind nebula (PWN) of PSR J1709-4429, in four epochs during 2018-2019. Comparison with an archival 2004 data set provides a pulsar proper motion μ = 13 ± 3 mas yr<SUP>-1</SUP> at a PA of 86° ± 9° (1σ combined statistical and systematic uncertainties), precluding birth near the center of SNR G343.1-2.3. At the pulsar ...About Kyr Grace. Over the course of my life, my mom has often said that "music is food.". Now my music on my first album, Dragonfly, is available to stream on Spotify (and other platforms). In some ways, the album is like a meal - full of different flavors and ingredients that synchronously and improbably come together to make something ...c ≡ P/2P˙ ∼ 5 kyr, and its spin-period of 16 ms makes it the fastest non-recycled pulsar known. PSR J0537−6910is one of only a handful of young (τ c < 10 kyr), energetic pulsars (of which the Crab pulsar is the prototype) that are known. No radio pulsations were detected in a search [4] conducted soon after its discovery in X-rays.In the first instance, we assume that the age of PSR J0002+6216 is equal to its characteristic age (τ c = 306 kyr). In this case, our measured proper motion places the pulsar birthplace more than 2° away, well outside the boundaries of CTB 1. In this instance, there is no physical PSR-SNR association, just a line-of-sight coincidence.PSR B1509-58 ! Young pulsars, e.g. Crab, PSR 1509-58 reach maximum luminosity below 100 MeV ! Middle-aged Vela and older pulsars reach max. luminosity at GeV energies ! High-energy spectra of young pulsars are different from spectra of older γ-ray pulsars: L X/L γ larger for young pulsars!pulsars with τc < 10 kyr (see Table 2) However, luminosity range for the young pulsar population spans two orders of magnitude (so no strict conclusions can be made) Table 2 1400 MHz Luminosities of Young Rotation-powered Pulsars (with τc < 10 kyr) PSR τc (kyr) P (sec) L1400 (mJy kpc2) J1846-0258 0.72 0.051 < 50 B0531+21 (Crab) 1.24 0.033 56Timing observation of PSR J1849−0001 were extracted from the one-dimensional image using a region of full width 40″ centered on the pulsar position.

It is positionally coincident with the TeV γ-ray source HESS J1857+026, which has no other known counterparts. Young, energetic pulsars create wind nebulae, and more than a dozen pulsar wind nebulae have been ...PSR J2021+3651 has a rotation period P = 104 ms and P_dot = 9.6x10^{-14}, implying a characteristic age ~17 kyr and a spin-down luminosity E_dot ~ 3.4x10^{36}ergs/s.

The latter is much longer than the SNR age, indicating that PSR J0821-4300 was born spinning near its present period.PSR B0740-28 has a spin-frequency of 6 Hz and a characteristic (spin-down) age of 160 kyr. We monitor PSR B0740-28 for 1 hour per day with the 42-ft telescope and approximately weekly with the Lovell telescope.Maximum values of about 10 cm kyr- t are observed during stages 6.1, 5.2 and 3, and a pronounced peak of about 23 cm kyr-~ occurs during the LGM (Fig. Sb). The MAR for C37 alkenones and Core were calculated by multiplying the concentration values by the sedimentation rate and the measured dry bulk density (Fig. Sc and d).
