Wavelet analysis of a large sample of AGN at high radio frequencies
T. Hovatta, H. J. Lehto, M. Tornikoski
We have studied the characteristic timescales of 80 AGNs at 22, 37 and 90 GHz examining the properties of the wavelet method and comparing them to traditional Fourier-based methods…
Two Years of INTEGRAL monitoring of GRS 1915+105 Part 2: X-Ray Spectro-Temporal Analysis
J. Rodriguez, S. E. Shaw, D. C. Hannikainen +14
(abridged) This is the second paper presenting the results of two years of monitoring of GRS 1915+105 with \integral and \rxte and the Ryle Telescope. We present the X-ray spectral…
Statistical analyses of long-term variability of AGN at high radio frequencies
T. Hovatta, M. Tornikoski, M. Lainela +5
We present a study of variability time scales in a large sample of Active Galactic Nuclei at several frequencies between 4.8 and 230 GHz. We investigate the differences of various…
