Radio and X - ray nebulae associated with PSR J 1509 − 5850

چکیده
We have discovered a long radio trail at 843 MHz which is apparently associated with middle age pulsar PSR J1509−5850. The radio trail has a length of ∼ 7 arcmin. In X-rays, Chandra observations of PSR J1509−5850 reveal an associated X-ray trail which extends in the same orientation as the radio trail. Moreover, two clumpy structures are observed along the radio trail. The larger one is proposed to be the supernova remnant (SNR) candidate MSC 319.9-0.7. Faint X-ray enhancement at the position of the SNR candidate is found in the Chandra data.

X-ray Observations of Parsec-scale Tails behind Two Middle-aged Pulsars
Chandra and XMM-Newton resolved extremely long tails behind two middle-aged pulsars, J1509–5850 and J1740+1000. The tail of PSR J1509–5850 is discernible up to 5.6′ from the pulsar, which corresponds to the projected length l⊥ = 6.5d4 pc, where d = 4d4 kpc is the distance to the pulsar. The observed tail flux is 2× 10−13 erg s−1 cm−2 in the 0.5–8 keV band. The tail spectrum fits an absorbed pow...
متن کاملPSR J 1856 + 0245 : Arecibo Discovery of a Young , Energetic Pulsar Coincident with the TeV γ - ray Source HESS J 1857 + 026
We present the discovery of the Vela-like radio pulsar J1856+0245 in the Arecibo PALFA survey. PSR J1856+0245 has a spin period of 81ms, a characteristic age of 21 kyr, and a spin-down luminosity Ė = 4.6 × 10 ergs s. It is positionally coincident with the TeV γ-ray source HESS J1857+026, which has no other known counterparts. Young, energetic pulsars create wind nebulae, and more than a dozen p...

متن کاملTwo Pulsar Wind Nebulae: Chandra/xmm-newton Imaging of Gev J1417−6100
We report on Chandra ACIS and XMM-Newton MOS/PN imaging observations of two pulsar wind nebulae (K3/PSR J1420−6048 and G313.3+0.1=‘the rabbit’) associated with the Galactic unidentified γ-ray source GeV J1417−6100. With the excellent ACIS imaging the very energetic pulsar PSR J1420−6048 is separated from its surrounding nebula. This nebula has surprisingly little compact structure, although a f...
متن کاملX-ray Detection of PSR B1757−24 and its Nebular Tail
We report the first X-ray detection of the radio pulsar PSR B1757−24 using the Chandra X-ray Observatory. The image reveals point-source emission at the pulsar position, consistent with being magnetospheric emission from the pulsar. In addition, we detect a faint tail extending nearly 20 east of the pulsar, in the same direction and with comparable morphology to the pulsar’s well-studied radio ...
