چکیده

We present the results of a deep ROSAT HRI observation of the supernova remnant Kes 32 and the possibly associated pulsar PSR B1610-50. The supernova remnant shows strongly energy dependent complex structures in a comparison with the ASCA GIS and ROSAT PSPC data with low foreground absorption (NH ∼ 5 × 1021 cm−2). The pulsar is not seen in the HRI image indicating a high absorbing column density (NH >∼ 5×1022 cm−2) along the line of sight, making the physical connection between Kes 32 and PSR B1610−50unlikely. The elongated structure south of the pulsar, interpreted as a pulsar jet, might be an unrelated foreground emission.

We present X-ray observations of two young energetic radio pulsars, PSRs B1046−58 and B1610−50, and their surroundings, using archival data from the Advanced Satellite for Cosmology and Astrophysics (ASCA). The energetic pulsar PSR B1610−50 is detected in X-rays with a significance of 4.5σ. The unabsorbed flux, estimated assuming a power-law spectrum and a neutral hydrogen column density NH of ...

No detectable radio emission from the magnetar - like pulsar in Kes 75

The rotation-powered pulsar PSR J1846−0258 in the supernova remnant Kes 75 was recently shown to have exhibited magnetar-like X-ray bursts in mid2006. Radio emission has not yet been observed from this source, but other magnetar-like sources have exhibited transient radio emission following X-ray bursts. We report on a deep 1.9 GHz radio observation of PSR J1846−0258 with the 100-m Green Bank T...

The Distance of the SNR Kes 75 and PWN PSR J 1846 - 0258 System

The supernova remnant (SNR) Kes 75/PSR J1846-0258 association can be regarded as a certainty due to the accurate location of young PSR J1846-0258 at the center of Kes 75 and the detected bright radio/X-ray synchrotron nebula surrounding the pulsar. We provide a new distance estimate to the SNR/pulsar system by analyzing the HI and 13 CO maps, the HI emission and absorption spectra, and the 13 C...
