Apr 19, 1996 · We present radio observations of a region in the vicinity of the young pulsar PSR B1853+01 in the supernova remnant W44. The pulsar is located at the apex of an extended feature with cometary morphology. We argue on the basis of its morphology and its spectral index and polarization properties that this is a synchrotron nebula produced by the spin-down energy of the pulsar. The geometry and ...The sensitivity of the δ 18 O sw stack to regional differences and potential proxy or chronological biases in the dataset was tested by calculating δ 18 O sw stacks for various data subsets based on latitude, hemisphere, ocean basin, proxy type, and chronology (Fig. 3).The various stacks agree quite well over the last 200 kyr, suggesting …While 3/4 inch metal pipe or thick wall conduit, make a strong closet rod that won't sag, it's not very attractive to look at.

We also confirmed the existence of a candidate from an early Arecibo survey, PSR J2053+1718, its subsequent timing and polarimetry are also presented here. ...

PSR J1048-5832 is a Vela-like (P=123.6 ms; tau~20.3 kyr) gamma-ray pulsar detected by Fermi, at a distance of ~2.7 kpc and with a rotational energy loss rate dot{E}_{SD} ~2 x 10^{36} erg/s. The PSR J1048-5832 field has been observed with the VLT in the V and R bands.

The ...B, = 1.0 X 1012 G, and a characteristic age of 8.9 kyr. 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. The radio pulsations are highly dispersed and broadened by interstellar scattering, and

With kyr of PSR J2021+4026, therefore, we cannot constrain the glitch mechanism from the relation in Figure 6. The figure also shows that a relatively large jump in the spin-down rate ( ) is mainly accompanied by a large glitch size ( ), indicating the origin of the angular momentum transfer from the superfluid to the solid crust.Introduction 3 • PSR J0359+5414 is a radio-quiet pulsar • Spin-down power . • Distance kpc. • Age = kyr. • The PWN associated to this source has been observed in X-rays with a arcsec size (Zyuzin et al. 2018). • Detected by Fermi-LAT • At VHE has not been detected before by any IACT or EAS experiment. • HAWC detects an excess above in the 15-78PSR J1357−6429 is a young (characteristic age 7.3 kyr) and energetic (spin-down luminosityĖ = 3.1×10 36 ergs s −1 ) radio pulsar with a period of 166 ms (Camilo et al. 2004).
