X-ray Monitoring of AGN with MAXI
Abstract
MAXI, an X-ray all-sky monitor on the ISS, started observations in August 2009. MAXI scans the sky with the orbital revolution of the ISS. Most of positions in the sky is observed in a transit of 40-60 seconds every 90 minutes. The Gas Slit Camera (GSC) covers nearly 90% of the sky in a day in the 2-30 keV band. The light curves of more than a hundred sources are updated daily and reported on the web (http://maxi.riken.jp). A few bright AGNs like Mrk 421 and Cen A can be detected in a single scan. Fluxes of less bright sources such as 3C454.3 are measured on a daily basis. We present some examples of the X-ray light curves of AGN obtained with MAXI, and compare them with those in other wavebands, e.g. gamma rays and optical bands.
