Past sea surface temperatures (SST) in the northern and southern areas of the South China Sea have been reconstructed for the past 220 kyr using the U K 37 alkenone index. The SST profiles follow the glacial/interglacial pattern exhibiting differences between Last Glacial Maximum and Holocene that are 1°-3°C larger than those observed at the same latitudes in the Atlantic and Pacific Oceans..

produced by the birth supernova of PSR J1734-3333 could have already faded to undetectable brightness, estimates of which suggest timescales of 10-100 kyr. This and other considerations lead us to conclude that the pulsar is possibly older than 45-100 kyr. PSR J1734-3333 is a pulsar with rotational properties that place it betweenArts Agencies.

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 ...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.Variation cycles of MS and FeD/FeT. Wavelet analysis and power spectrum analysis show that there is a dominant 101 kyr cycle in the MS curve of the Madang profile (95% robust confidence intervals ...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.

PSR B1849+00 has a spin-down power of ∼4 × 10 32 erg s −1 and a surface magnetic field of ∼3 × 10 13 G (see Hobbs et al. 2004), located 8.4 ± 1.7 kpc from us (Cordes & Lazio 2003). To examine their relative contribution of γ -rays, we conservatively assume for each of them a shorter distance d = 7 kpc from us and a narrower beam solid ...PSR J1907+0602 was discovered as a γ-ray pulsar during a blind search for pulsations in unidentified Fermi-LAT sources (Abdo et al. 2009a; 2010). These characteristics make PSR J1907+0602 quite similar to the slightly younger (11.2 kyr) Vela pulsar (Manchester et al. 2005), one of the historical γ-ray pul-sars (e.g., Abdo et al. 2009b). ….

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.Sep 10, 2019 · The positive sloped gray lines indicate characteristic ages of 1 kyr, 100 kyr, 10 Myr, and 1 Gyr. The negative sloped gray lines correspond to inferred surface magnetic-field strengths of 10 GG, 100 GG, 10 TG, and 100 TG. Magnetars (green), XDINSs (orange), RRATs (yellow), and the 8.5-s radio pulsar PSR J2144–3933 are indicated on the plot.

Many of them are luminous above a hundred TeV without a hint of a spectral cutoff (e.g.,Abeysekara et al.(2020) andSu-doh et al.(2021)). Recently, the higher energy regimeThe nine pulsars have spin frequencies between 3 and 12 Hz, and characteristic ages ranging from 17 kyr to 3 Myr.
