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.PSR J1734-333 3 is a rad io pulsar with a period P = 1.17 s and a period derivative ˙ P = 2 . 28 × 10 − 12 . It is located between the normal rad io pulsars and anomalous X-ray pulsars (AXPs ...

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 ...The data base was used to study the glitch activity among the pulsar population, finding that it peaks for pulsars with a characteristic age τ c ∼ 10 kyr and decreases for longer values of τ c, disappearing for objects with τ c > 20 Myr. The glitch activity is also smaller in the very young pulsars (τ c ≲ 1 kyr). The cumulative effect ...We present results of the timing observations of the 143 ms pulsar PSR J0538+2817 that provide a proper-motion measurement clearly showing an association of the pulsar with the supernova remnant S147. We measure a proper motion of 67 mas yr-1, implying a transverse velocity of v = 385 km s-1. We derive an age of the pulsar and S147 of only 30 ± 4 kyr, which is a factor of 20 times less than ...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.

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)."

Abstract. We report the discovery of an extended very-high-energy (VHE) gamma-ray source around the location of the middle-aged (207.8 kyr) pulsar PSR J0622+3749 with the Large High-Altitude Air Shower Observatory (LHAASO). The source is detected with a significance of 8.2σ for E>25 TeV assuming a Gaussian template.Sep 20, 2011 · 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.

cupid costume women PSR J0738-4042 underwent a switching between two- and three-components of the pulse profile since its first spin-down state transition event occurred in September 2005 (Brook et al. 2014). The triple-peaked profile of PSR J0738-4042 contains a dominant trailing component, preceded by two obvious shoulder peaks (Brook et al. 2016 ).Apr 23, 2021 · We present the discovery and timing of the young (age ∼28.6 kyr) pulsar PSR J0837–2454. Based on its high latitude ( b = 98) and dispersion measure (DM = 143 pc cm −3 ), the pulsar appears to be at a z -height of >1 kpc above the Galactic plane, but near the edge of our Galaxy. menu for mcdonaldshopping at kohl Abstract In this study, we used a ~47.0-kyr record of Sr-Nd isotopic data derived from lake sediments in Dahu swamp in the eastern Nanling Mountains to explore the possible changes in the source of sediments, and to provide insights into the East Asian winter monsoon (EAWM) driven climatic signals. Based on Sr-Nd isotopic results, we argued that local weathered granitic residues were the ... e hential 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.The pulsar is as young as the Vela pulsar (characteristic age τ c = 10 kyr), as energetic (erg s −1), and is evidently the energy source of the "Boomerang" arc-shaped PWN G106.65+2.96, suggested to be part of the supernova remnant ...

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.

With a characteristic age of only 250 kyr, PSR J0627+0706 is by far the most energetic object in this sample. This object displays a prominent interpulse, suggesting an orthogonal rotator. It also has significant timing noise, which is typical of young pulsars. This is the reason for the large reduced χ 2 of its solution.
