F-GAMMA: On the phenomenological classification of continuum radio spectra variability patterns of Fermi blazars
F-GAMMA phenomenological classification continuum radio spectra variability patterns Fermi blazars
2012/2/21
The F-GAMMA program is a coordinated effort to investigate the physics of Active Galactic Nuclei (AGNs) via multi-frequency monitoring of Fermi blazars. In the current study we show and discuss the ev...
The Nature and Cause of Spectral Variability in LMC X-1
Nature Cause Spectral Variability LMC X-1
2011/10/21
We present the results of a long-term observation campaign of the extragalactic wind-accreting black-hole X-ray binary LMC X-1, using the Proportional Counter Array on the Rossi X-Ray Timing Explorer ...
Varying disc-magnetosphere coupling as the origin of pulse profile variability in SAX J1808.4-3658
accretion accretion discs – pulsars:individual:SAX J1808.4–3658 – stars:neu-tron – X-rays:binaries
2011/9/26
Accreting millisecond pulsars show significant variability of their pulse profiles, especially at low accretion rates. On the other hand, their X-ray spectra are remarkably similar with not much varia...
