Opacity effects and shock-in-jet modelling of low-level activity in Cygnus X-3
James C. A. Miller-Jones, Michael P. Rupen, Marc Türler +3
We present simultaneous dual-frequency radio observations of Cygnus X-3 during a phase of low-level activity. We constrain the minimum variability timescale to be 20 minutes at 43…
Synchrotron flaring behaviour of CygnusX-3 during the February-March 1994 and September 2001 outbursts
E. J. Lindfors, M. Türler, D. C. Hannikainen +4
Aims: In this paper we study whether the shock-in-jet model, widely used to explain the outbursting behaviour of quasars, can be used to explain the radio flaring behaviour of the…
Synchrotron Flaring in Galactic and Extragalactic jets
Elina Lindfors, Marc Türler
We study the synchrotron flaring behaviour of the blazar 3C 279 and microquasar Cyg X-3. The properties of a typical outburst are derived from the observations by decomposing multi…
INTEGRAL observations of the cosmic X-ray background in the 5-100 keV range via occultation by the Earth
E. Churazov, R. Sunyaev, M. Revnivtsev +32
We study the spectrum of the cosmic X-ray background (CXB) in energy range 5-100 keV. Early in 2006 the INTEGRAL observatory performed a series of four 30ksec observations wi…
