MAXI detection of new transients

MAXI, Monitor of All-sky X-ray Image, on board the ISS monotors all the sky every 92 min, and the detection limit reachs down to about 15 mCrab (4-20 keV) a day. With the high sensitivity, MAXI has newly discovered 6 black hole candadidates (MAXI J1659-152/GRB 100925A, J1543-564, J1836-194, J1305-704, J1910-057/Swift J1910.2-0545, J1828-249), 5 neutron-star binaries (MAXI J1409-619, J0556-332, J1647-227, J1735-304/Swift J1734.5-3027, J1421-613), and 1 white dwarf binary (MAXI J0158-744) since the operation started in August 2009. Some of them were independently discovered with Swift/BAT as well. MAXI also detected renew activties and state transitions of known X-ray novae, and very bright X-ray stellar flares. In the talk, I introduce the nature and distict properties of the new sources, focusing on differences from previous and current all-sky high-energy monitors and surveys.
