Suzaku observations of two Galactic black hole candidates XTE J1752-223 and MAXI J1659-152 triggered by MAXI
Abstract
Following the MAXI detection and discovery of two Galactic black hole candidates (BHCs) XTE J1752-223 and MAXI J1659-152, we carried out Suzaku DDT ToO observations once on Feb. 23, 2010 and three times on Sep. 28, 30, and Oct. 1, 2010 for each source. These observations have been done in approved observation scheme of Suzaku-MAXI collaborations. As for XTE J1752-223, Suzaku observed a high/soft state where the disk emissions with an innermost temperature of about 0.5 keV are dominant in the broadband spectrum, whereas, for MAXI J1659-152, it observed an intermediate state where both soft and hard component are dominant. In this paper, we will show the preliminary results and discuss the origin of the broadband spectrum for two BHCs in the different spectral states.
