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.We report the analysis of the first deep optical observations of three isolated γ-ray pulsars detected by the Fermi Gamma-ray Space Telescope: the radio-loud PSR J0248+6021 and PSR J0631+1036, and the radio-quiet PSR J0633+0632. The latter has also been detected in the X-rays. The pulsars are very similar in their spin-down age (τ ∼ 40-60 kyr), spin-down energy (dot{E} ∼ 10^{35} erg s ...

PSR J1928+1725 could be similar to the young and energetic (τ c = 865 kyr and erg s −1) 125 ms PSR J1554−5209 (Keane et al. 2010), one of the very few RRATs having a spin period <500 ms for which has been measured. 37 Keane et al. conducted a timing analysis on PSR J1554−5209 along with a dozen more RRATs with longer periods and lower ...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 ...We report the discovery of PSR J2022+3842, a 24 ms radio and X-ray pulsar in the supernova remnant G76.9+1.0, in observations with the Chandra X-ray telescope, the Robert C. Byrd Green Bank Radio Telescope, and the Rossi X-ray Timing Explorer (RXTE). The pulsar's spin-down rate implies a rotation-powered luminosity Edot = 1.2 x 10^{38} erg/s, a surface dipole magnetic field strength B_s = 1.0 ...
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, …PSR B0540-69 is the first young pulsar detected to have a spin-down rate transition. It results in a delayed brightening of its pulsar wind nebula ... with a characteristic age kyr. PSR B1931+24 shows periodical emission behavior, which could switch off in 10 s (Kramer et al. 2006).The Bridgewater Associates founder said investing is a zero-sum game like poker, and compared life to a video game and lessons to precious gems. Jump to Ray Dalio compared markets ...Climate variability over the past 800,000 years has long been described as being dominated by ~100-kyr glacial cycles, and researchers have debated whether these glacial cycles were driven by ...These spin parameters imply a characteristic age c ¼ 4:8 kyr and a spin-down luminosity E˙ ¼ 3:3 ; 1037 ergs s 1, ... G21.5-0.9 and PSR J1833 1034 are much younger than c and likely their true age is P1000 yr. In that case, the initial spin period of the pulsar wask55 ms.
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 ...PSR J2004+3429 is a young pulsar with a characteristic age of ∼18 kyr. We currently rule out that PSR J2004+3429 is associated with near-by SNR G069.7+01.0, due to the high transverse velocity required to place the pulsar at its current position with respect to the remnant in the time-scale suggested by its characteristic age.Don't overestimate your home improvement abilities.

Although the contents of CaCO 3 were very low in PC-4 over the last 30 kyr, alkenones (0.2 ∼ 1.0 μg g −1) were abundantly detected throughout the last 15 kyr. Strong carbonate dissolution has recently been reported to occur in the water column of the modern Okhotsk Sea during sinking of carbonate particles.We present a timing analysis of PSR J1602-5100 using approximately seven years of observations from the Parkes 64-m radio telescope. A slow glitch that occurred between 2008 September 24 and 2010 May 14 (MJDs 54733 and 55330) is identified. During this time, the pulsar showed a slow exponential growth in the spin frequency ν$\\nu$, and the spin-down rate |ν˙|$|\\dot{\\nu}|$ suddenly ...

But the time derivative of its spin down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.
