Approximately half of the specimens yielded results that passed strict data selection criteria and give high-fidelity paleointensities.Furthermore, archaeomagnetic studies focusing on the detailed evolution of the geomagnetic field over the past ∼8 kyr have a potential application on archaeomagnetic dating (Ben-Yosef et al., 2008b, Ben-Yosef et al., 2010, Pavón-Carrasco et al., 2009, Pavón-Carrasco et al., 2011). The geomagnetic field varies over a broad range of timescales.[1] Deep-sea foraminiferal δ 13 C records contain abundant 400-kyr cycles indicating a link between eccentricity forcing and ocean carbon reservoir change. Here we simulate the oceanic δ 13 C maxima events forced by the Earth's orbital geometry during the Miocene Climate Optimum (MCO, 17-14 Ma) using a box model. The simulated results of both surface and deep water δ 13 C display co-varying ...KYR is listed in the World's most authoritative dictionary of abbreviations and acronyms.

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 ...Abstract. During the search for counterparts of very-high-energy gamma-ray sources, we serendipitously discovered large, extended, low surface brightness emission from PWNe around pulsars with the ages up to ∼ similar-to \sim ∼ 100 kyrs, a discovery made possible by the low and stable background of the Suzaku X-ray satellite. A systematic study of a sample of 8 of these PWNe, together with ...PSR B0355+54 (J0358+5413; hereafter B0355) is a radio-loud pulsar with characteristic age ˝= 564 kyr and spin-down power E_ = 4:5 1034 erg s 1.

Located in supernova remnant G76.9+1.0, and spatially coincident with a Fermi LAT source, pulsations with a period of ~48.6 ms have been reported in radio by the GBT, as well in the X-ray band by Chandra, RXTE, and XMM-Newton.The survey has so far resulted in the discovery of 15 radio pulsars, including a pulsar with a characteristic age of ∼18 kyr, PSR J2004+3429, and a highly eccentric, binary millisecond pulsar ...energetic pulsars exception ms-pulsar PSR J02184232 ; The only established galactic source population emittingg-rays over a wide (0.5 keV 10 GeV)We report on XMM-Newton EPIC observations of the young pulsar J2022+3842, with a characteristic age of 8.9 kyr. We detected X-ray pulsations and …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.We present the discovery of the Vela-like radio pulsar J1856 0245 in the Arecibo PALFA survey. PSR J1856 0245 has a spin period of 81 ms, a characteristic age of 21 kyr, and a spin-down luminosity ergs s .

Young,A similar upward evolution is seen for PSR J1734-3333, which has a measured n of 0.9±0.2 (Espinoza et al. 2011b) and is speculated to attain the rotational properties of a magnetar in ∼ 30 kyr ...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.PSR 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, …Composer Robert Kyr embraces peace, love, and nature. by Lydialyle Gibson.
