On the Nature of AX J2049.6+2939 and AX J2050.0+2914
Emi Miyata, Kouji Ohta, Kenichi Torii +4
AX J2049.6+2939 is a compact X-ray source in the vicinity of the southern blow-up region of the Cygnus Loop supernova remnant (Miyata et al. 1998a). This source was the brightest X…
Discovery of 101-s Pulsations from AX J0057.4-7325 in the SMC with ASCA
Jun Yokogawa, Ken'ichi Torii, Takayoshi Kohmura +2
The results from two ASCA observations of AX J0057.4-7325 = RX J0057.3-7325 are presented. Coherent pulsations with a barycentric period of 101.45 +/- 0.07 s were discovered in the…
Discovery of 172-s Pulsations from a Be/X-ray Binary Candidate AX J0051.6-7311 in the SMC with ASCA
Jun Yokogawa, Ken'ichi Torii, Kensuke Imanishi +1
The results from three ASCA observations of AX J0051.6-7311 = RX J0051.9-7311 are reported. Coherent pulsations with a barycentric period of 172.40 +/- 0.03 s were discovered in th…
Discovery of a Slow X-Ray Pulsator, AX J1740.1-2847, in the Galactic Center Region
Masaaki Sakano, Ken'ichi Torii, Katsuji Koyama +2
We report the discovery of an X-ray pulsar AX J1740.1-2847 from the Galactic center region. This source was found as a faint hard X-ray object on 7--8 September 1998 with the ASCA…
ASCA Observation of the Crab-Like Supernova Remnant 3C58
Ken'ichi Torii, Patrick O. Slane, Kenzo Kinugasa +2
We present here the X-ray observation of a Crab-like supernova remnant (SNR) 3C58 with ASCA. We find that the integrated energy spectrum over the nebula is consistent with previous…
A Giant Glitch in the Energetic 69 ms X-ray Pulsar AXS J161730-505505
K. Torii, E. V. Gotthelf, G. Vasisht +2
We present new results on the recently discovered 69 ms X-ray pulsar AXS J161730-505505, the sixth youngest sample of all known pulsars. We have undertaken a comprehensive X-ray ob…
