The Young Pulsar J1357-6429 and Its Pulsar Wind Nebula
Chulhoon Chang, George G. Pavlov, Oleg Kargaltsev +1
We observed the young pulsar J1357--6429 with the {\it Chandra} and {\it XMM-Newton} observatories. The pulsar spectrum fits well a combination of absorbed power-law model ($Γ=1.7\…
Extended X-ray emission in the vicinity of the microquasar LS 5039: pulsar wind nebula?
Martin Durant, Oleg Kargaltsev, George G. Pavlov +2
LS 5039 is a high-mass binary with a period of 4 days, containing a compact object and an O star, one of the few high-mass binaries detected in gamma-rays. Our Chandra ACIS observa…
Extended Emission from the PSR B1259-63/SS 2883 Binary Detected with Chandra
George G. Pavlov, Chulhoon Chang, Oleg Kargaltsev
PSR B1259-63 is a middle-aged radio pulsar (P=48 ms, tau=330 kyr, Edot=8.3*10^{35} erg/s) in an eccentric binary (P_orb =3.4 yr, e=0.87) with a high-mass Be companion, SS 2883. We…
Probing Shock Properties with Non-thermal X-ray Filaments in Cas A
Miguel Araya, David Lomiashvili, Chulhoon Chang +2
Thin non-thermal X-ray filaments are often seen in young supernova remnants. We used data from the 1 Ms Chandra observation of Cassiopeia A to study spectral properties of some of…
