For PSR J1901+0658, the Shapiro delay would be only approximately 0.1 ms for a very edge-on orbit (sin i = 0.999 𝑖 0.999 \sin{i}=0.999 roman_sin italic_i = 0.999). Good luck is needed for measuring the Shapiro delay of this weak pulsar over the 14.5-day orbit because the current TOA uncertainties measured by FAST are in the range of 0.03 ...Three of these pulsars are in binary systems, consisting of a redback (PSR J2055+1545), a black widow (PSR J1630+3550), and a neutron star-white dwarf binary (PSR J2116+1345). The fourth MSP, PSR J2212+2450, is isolated.

Ruthless and cold, Kyr climbed to the top rank of the League High Command by killing anyone who stood in his way. Out of all the assassins sent after Nykyrian, he was the only one who survived. Something he hasn't forgotten since that encounter cost him his right eye. He's never been happy about the fact that the League pardoned Nykyrian.We report on the setup and initial discoveries of the Northern High Time Resolution Universe survey for pulsars and fast transients, the first major pulsar survey conducted with the 100-m Effelsberg radio telescope and the first in 20 years to observe the whole northern sky at high radio frequencies. Using a newly developed 7-beam receiver system combined with a state-of-the-art polyphase ...The velocity and characteristic age of PSR J1825-1446 make it incompatible with SNR G016.8-01.1. There are no clear OB associations or SNRs crossing the past trajectory of PSR J1825-1446. We estimate the age of the pulsar to be 80-245 kyr, which is compatible with its characteristic age.Dec 9, 2021 · For the pulsar PSR J1734-3333, both the estimated SNR age (23 kyr) [35] and proper motion age (45-100 kyr) [94] are much older than its characteristic age (8.1 kyr), which might hint at the fact ...The artifacts used in this study were collected from four different provinces of Shandong, Liaoning, Zhejiang and Hebei, which are located at eastern China (Fig. 1).The archaeological structures cover living sites, saltern and kilns (Table 1) with materials varying from baked clay, pottery, porcelain to slag, spanning the past ∼ 7 kyr (Fig. 2).Because …
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.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 ... ….

Within the boundaries of S147, a 143 ms pulsar PSR J0538+2817 was discovered by Anderson et al. (1996) in an undirected pulsar survey using the 305 m Arecibo radio tele-scope. The pulsar has a large characteristic age τc = P/2P˙ = 620 kyr and a dispersion measure (DM)-estimated distance of 1.2 kpc. Based on the positions and distances of PSRWe discuss PSR J1740+1000, one of five pulsars recently discovered in a search of 470 deg 2 at 430 MHz during the upgrade of the 305 m Arecibo Telescope. The period P=154 ms and period derivative P=2.1×10 -14 s s -1 imply a spin-down age τ s =P/2P=114 kyr that is smaller than 95% of all known pulsars. The youth and proximity of this pulsar ...

Logger Interface: Defines a common interface for logging libraries, making it easier to switch between different logging implementations. PSR-4.Because no glitches were found in the latest 7.1 yr of timing data, this extends the time without a detected glitch for PSR B1509−58 to 28.4 yr. While the youngest pulsars (τ c < 2 kyr) tend to have smaller and fewer glitches than somewhat older pulsars (τ c ∼ 5–10 kyr), PSR B1509−58 is extreme in its lack of glitches.
