Abstract:

Since 2009, the MAXI (Monitor of All-sky X-ray Image) experiment on the ISS has been conducting all-sky X-ray monitoring. With MAXI, we detected flaring activities of a few blazers, including Mrk 421, Mrk 501, and 3C 454.3. Recently, new X-ray flaring activities were detected from two blazers, MAXI J1930+093 = 2FGL J1931.1+0938 (ATel#5943) and 2MAXI J0243-582 = BZB J0244-5819 (ATel#6012). The MAXI monitoring also covers black-hole binaries, including Cyg X-1 and Cyg X-3 which emit GeV gamma-rays. Their gaamma-ray emission was found to coincide with their X-ray state transitions. We present light curves and outstanding events of these sources.
