Simultaneous observations of the X-ray and IR flares of GRS 1915+105

GRS 1915+105 is the most prominent microquasar and the most energetic object inour Galaxy. It has remained unique among its class for the large variety oftemporal behaviours in different time scales. Multiwavelength observationsshowing radio, IR and Xray oscilations, with time delays depending on thewavelength, revealed in the past the intimate link between the accretion discand the jet ejection. However, the mechanism of jet formation and the origin ofthe delay between the flares in different wavelengths remains unclear. Here wepropose simultaneous Xray and IR observations of GRS 1915+105 withunprecedented high time resolution, using EPICpn in Burst mode and VLT/ISAAC.sAladdin array in its new Burst mode, with integration times as short as 3.2ms. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
