A Technique for Estimating the Absolute Gain of a Photomultiplier Tube
M. Takahashi, Y. Inome, S. Yoshii +26
Detection of low-intensity light relies on the conversion of photons to photoelectrons, which are then multiplied and detected as an electrical signal. To measure the actual intens…
A Hard-to-Soft State Transition of Aquila X-1 Observed with Suzaku
Ko Ono, Kazuo Makishima, Soki Sakurai +3
The recurrent soft X-ray transient Aquila X-1 was observed with Suzaku for a gross duration of 79.9 ks, on 2011 October 21 when the object was in a rising phase of an outburst. Dur…
Suzaku Observation of the High-Inclination Binary EXO 0748-676 in the Hard State
Zhongli Zhang, Soki Sakurai, Kazuo Makishima +4
Utilizing an archived Suzaku data acquired on 2007 December 25 for 46 ks, X-ray spectroscopic properties of the dipping and eclipsing low-mass X-ray binary EXO 0748676 were stud…
