Discovery of a 9-s X-Ray Pulsar, AX J0049-732, in the Small Magellanic Cloud
Masaru Ueno, Jun Yokogawa, Kensuke Imanishi +1
We report the ASCA discovery of a new X-ray pulsar, AX J0049-732, in the Small Magellanic Cloud (SMC). The pulse shape is sinusoidal with a barycentric period of 9.1320 +/- 0.0004…
ASCA Discovery of Diffuse 6.4 keV Emission Near the Sgr C Complex: A New X-ray Reflection Nebula
H. Murakami, K. Koyama, M. Tsujimoto +2
We present an ASCA discovery of diffuse hard X-ray emission from the Sgr C complex with its peak in the vicinity of the molecular cloud core. The X-ray spectrum is characterized by…
Discovery of the Slowest X-Ray Pulsar in the SMC, AX J0049.5-7323, with ASCA
Jun Yokogawa, Kensuke Imanishi, Masaru Ueno +1
The discovery of coherent pulsations with ASCA from an X-ray source, AX J0049.5-7323, is reported. The barycentric period was determined to be 755.5 +/- 0.6 s, which is the longest…
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…
ASCA Observations of the Twin Supernova Remnants in the Large Magellanic Cloud, DEM L316
Mamiko Nishiuchi, Jun Yokogawa, Katsuji Koyama +1
We report results from an ASCA X-ray study of DEM L316, an emission nebula in the Large Magellanic Cloud (LMC) consisting of two closely-spaced supernova remnants (SNRs). The SIS i…
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…
