EUVE-RXTE simultaneous observations of NGC 4051: variability and spectrum.
Abstract
The authors present timing and spectral analysis of the data collected by the Extreme Ultraviolet Explorer Satellite (EUVE) for the Seyfert 1 galaxy NGC 4051 during 1996. The observations were always simultaneous with hard X-ray observations conducted with the Rossi X-Ray Timing Explorer (RXTE). The EUVE light curves are extremely variable during each observation. The authors illustrate the results of their spectral and detailed power spectrum analysis performed on EUVE data and the comparison with RXTE lightcurves and discuss the constraint they can place on the mass of the central object and on the size of the emitting region.
