MIRAX: the galactic bulge transient monitor mission

摘要

Monitor e Imageador de RAios-X (MIRAX) is a Brazilian high energy astronomy mission dedicated to monitoring the central 1000 sq. deg. of the Galactic plane to observe unpredictable transient phenomena from compact objects in the 2-200 keV range through nearly continuous imaging with good spatial/temporal/energy resolution. The strength of MIRAX lies in the departure of its observing strategy from traditional pointed programs and scanning monitors. MIRAX will achieve two major advantages over previous and existing missions. First, it will detect, localize, and study transient phenomena, which last on all timescales from milliseconds to years, and are very likely to be missed by traditional observing strategies. Second, MIRAX will study longer lived phenomena in exquisite detail. The mission elements and science will be presented.
