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.Pulsar research at soft g -rays. s.

This system has recently b eenAbstract. 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 ...[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 ...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 J 0622 +3749 with the Large High-Altitude Air Shower Observatory (LHAASO).

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 U.S. Department of Energy's Office of Scientific and Technical InformationSep 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.Abstract and Figures. PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April ...We present results of timing observations of the 143-ms pulsar J0538+2817 that provide a proper motion measurement which clearly associates the pulsar with the supernova remnant S147. We measure a proper motion of 67 mas yr, implying a transverse velocity of km s. We derive an age of the pulsar and S147 of only kyr which is a factor of 20 times ...We report the discovery of PSR J1906+0746, a young 144 ms pulsar in a highly relativistic 3.98 hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence time of ~300 Myr. The new pulsar was found during precursor survey observations with the Arecibo 1.4 GHz feed array system and retrospectively detected in the Parkes Multibeam plane pulsar survey data. From radio ...PSR J1811-1925 - the pulsar at the heart of G11.2-0.3. G11.2-0.3 is a young supernova remnant plausibly associated with the historical "guest star" witnessed by Chinese astronomers in the year 386 AD ( Clark and Stephenson, 1977 ).

If PSR J2021+3651 was born near the centroid of eHWC J2019+368 and traveled to the current location at a constant speed, the corresponding transverse velocity of the pulsar is km s −1, where t 16 is the true age scaled to 16 kyr.

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.PSR J2021+3651 is a 17 kyr old rotation powered pulsar detected in the radio, X-rays, and -rays. It powers a torus-like pulsar wind nebula with jets, dubbed the Dragonfly, which is very similar to that of the Vela pulsar. The Dragonfly is likely associated with the extended TeV source VER J2019+368 and extended radio emission.The SNR 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.PSR J1838-0537: DISCOVERY OF A YOUNG, ENERGETIC GAMMA-RAY PULSAR.
