Discovery of Pulsations from AXJ1749.1-2733: Characterization and Localization

This study by Karasev D., Tsygankov S., Lutovinov A. (2007) presents the discovery of pulsations from AXJ1749.1-2733, determining its counterpart and characteristics such as pulsations, spectrum, and localization. Key findings include Γ=1.02±0.18, Ecut=7.1±1.9 keV, Ef.=19.8±4.0 keV, NH=(20.2±2.7)*10^22 cm^-2. Observations from INTEGRAL (09.03) and XMM (03.07) are discussed, including RTT-150 and possible supergiant nature with T~20000K and PF ~25-50%.
