Testing the blazar spectral sequence: X-ray selected blazars
L. Maraschi, L. Foschini, G. Ghisellini +2
We present simultaneous optical and X-ray data from Swift for a sample of FSRQs selected from the EMSS survey. We present also a complete analysis of Swift and INTEGRAL data on 4 b…
The Spectral Sequence of Blazars - Status and Perspectives
L. Maraschi, G. Ghisellini, F. Tavecchio +2
The present status of the blazar spectral sequence is discussed, including new findings about blazars selected with different criteria than the original complete radio-samples. Des…
The application of slim disk models to ULX: the case of M33 X-8
L. Foschini, K. Ebisawa, T. Kawaguchi +8
A comparative XMM-Newton archival data spectral study of the ultraluminous X-ray source (ULX) M33 X-8 has been performed by using both the standard disk model and the newly develop…
GRB 021219: the first Gamma-Ray Burst localized in real time with IBAS
S. Mereghetti, D. Gotz, V. Beckmann +5
On December 19, 2002, during the Performance and Verification Phase of INTEGRAL, a Gamma-Ray Burst (GRB) has been detected and localized in real time with the INTEGRAL Burst Alert…
Yet another galaxy identification for an ultraluminous X-ray source
N. Masetti, L. Foschini, L. C. Ho +4
We report on the identification of the optical and infrared counterparts of the ultraluminous X-ray source (ULX) XMMU J121214.5+131248 (NGC4168-ULX1). The optical spectrum yields a…
Radiative acceleration and transient, radiation-induced electric fields
L. Zampieri, R. Turolla, L. Foschini +1
The radiative acceleration of particles and the electrostatic potential fields that arise in low density plasmas hit by radiation produced by a transient, compact source are invest…
