We present the first results of simultaneous INTEGRAL and RXTE observations of the microquasar GRS 1915+105. We focus on the analysis of the unique highly variable observation and show that we might have observed a new class of variability. We then study the energetic depenelence of a low frequency QPO from our steady observations.

Resumen

Presentamos los primeras resultados de observaciones INTEGRAL y RXTE simultáneous del microcuasar GRS 1915+105. Nos enfocamos en el análisis de la única observación altamente variable, mostrando quе pudimos haber observado una nueva clase de variabilidad. Luego estuediamos la dependencia energética de una, QPO con base en nuestras observaciones regulares.
