Chandra observation of the relativistic binary J1906+0746
O. Kargaltsev, G. G. Pavlov
PSR J1906+0746 is a 112-kyr-old radio pulsar in a tight relativistic binary with a compact high-mass companion, at the distance of about 5 kpc. We observed this unique system with…
Detection of X-ray Emission from the Very Old Pulsar J0108-1431
G. G. Pavlov, O. Kargaltsev, J. A. Wong +1
PSR J0108-1431 is a nearby, 170 Myr old, very faint radio pulsar near the "pulsar death line" in the P-Pdot diagram. We observed the pulsar field with the Chandra X-ray Observatory…
X-ray Observations of Parsec-Scale Tails behind Two Middle-Aged Pulsars
O. Kargaltsev, Z. Misanovic, G. G. Pavlov +2
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…
X-ray emission from PSR J1809-1917 and its pulsar wind nebula, possibly associated with the TeV gamma-ray source HESS J1809-193
O. Kargaltsev, G. G. Pavlov
We detected X-ray emission from the 50-kyr-old pulsar J1809-1917 and resolved its pulsar wind nebula (PWN) with Chandra. The pulsar spectrum fits PL+BB model with the photon index…
X-ray emission from the planet pulsar B1257+12
G. G. Pavlov, O. Kargaltsev, G. P. Garmire +1
We report the detection of the millisecond pulsar B1257+12 with the Chandra X-ray Observatory. In a 20 ks exposure we detected 25 photons from the pulsar, with energies between 0.4…
The Vela Pulsar in the Ultraviolet
Roger W. Romani, Oleg Kargaltsev, George G. Pavlov
We describe time-tagged observations of the Vela pulsar (PSR B0833-45) with the HST STIS MAMA-UV detectors. Using an optimal extraction technique, we obtain a NUV light curve and c…
