The same conclusion is reached by comparing every 400-kyr-long interval in increments of 100 kyr with the 0-800 kyr period . These results point out the absence of any dominant stable periodicity.HESS J1928+181 is the H.E.S.S. detection of HAWC J1928+178, a source of unknown astronomical origin. It may be associated with the middle-aged pulsar (82 kyr) PSR J1928+1746 ,, located 4.3 kpc away.It has been detected in radio wavelength and has a spin-down power of dE/dt = 1.6 × 10 36 erg s −1.In that case, the γ-ray emission would come from inverse Compton (IC) scattering of e ± from ...The properties of PSR J0726-2612 strongly resemble those of the INSs, except for its much shorter characteristic age of 200 kyr (instead of several Myr). 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 …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 between standard ...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.

W44 hosts the pulsar PSR B1853+01, a 20 kyr pulsar with dE/dt= 4.3 x 10e35 erg s-1 located approx. 3 kpc away. W44 has not been detected by H.E.S.S. during the HGPS, but H.E.S.S. reported significant emission with only one of their analysis chains at the location of W44, without claiming a detection (Abdalla et al., 2018)."LHAASO J1839-0545.

The...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-7: HTTP message interfaces.

The sensitivity of the δ 18 O sw stack to regional differences and potential proxy or chronological biases in the dataset was tested by calculating δ 18 O sw stacks for various data subsets based on latitude, hemisphere, ocean basin, proxy type, and chronology (Fig. 3).The various stacks agree quite well over the last 200 kyr, suggesting …[1] Stable isotope data from eastern equatorial Pacific (EEP) core TR163-19 (2°15′N, 90°57′W, 2348 m) are presented for the surface-dwelling foraminifers Globigerinoides ruber and G. sacculifer and thermocline-dwelling Globorotalia menardii and Neogloboquadrina dutertrei.Using species-specific normalization factors derived from experimental and plankton tow data, we reconstruct a 360 kyr ...Abstract. Context. 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. G354.8-0.8 is a supernova remnant (SNR ...Robert Kyr poses in St. Martin's Lutheran Church in Austin, Texas.

We significantly refine the proper motion to μ = 35.3 ± 0.6 mas yr<SUP>-1</SUP> and place new constraints on the distance, with the overall effect of lowering the velocity and increasing the inferred age to 47.60 ± 0.80 kyr.
