X-ray radiation of the jets and the supercritical accretion disk in SS 433
S. Fabrika, A. Medvedev
The observed X-ray luminosity of SS 433 is ~10^36 erg/s, it is known that all the radiation is formed in the famous SS 433 jets. The bolometric luminosity of SS 433 is ~10^40 erg/s…
Magic constraints on Gamma-ray emission from Cygnus X-3
J. Aleksić, L. A. Antonelli, P. Antoranz +156
Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy gamma rays…
Study of Envelope Velocity Evolution of Type Ib-c Core-Collapse Supernovae from Observations of XRF 080109 / SN 2008D and GRB 060218 / SN 2006aj with BTA
A. S. Moskvitin, E. Sonbas, V. V. Sokolov +2
Results of modeling the spectra of two supernovae SN 2008D and SN 2006aj related to the X-ray flash XRF 080109 and gamma-ray burst GRB / XRF 060218, respectively, are studied. The…
The Eastern Filament of W50
P. Abolmasov, O. Maryeva, A. N. Burenkov
We present new spectral (FPI and long-slit) data on the Eastern optical filament of the well known radionebula W50 associated with SS433. We find that on sub-parsec scales differen…
The Hardness-Intensity Diagram of Cygnus X-3: Revisiting the Radio/X-Ray States
K. I. I. Koljonen, D. C. Hannikainen, M. L. McCollough +2
Cygnus X-3 is one of the brightest X-ray and radio sources in the Galaxy, and is well known for its erratic behaviour in X-rays as well as in the radio, occasionally producing majo…
Suzaku and Optical Spectroscopic Observations of SS 433 in the 2006 April Multiwavelength Campaign
Kaori Kubota, Yoshihiro Ueda, Nobuyuki Kawai +9
We report results of the 2006 April multi-wavelengths campaign of SS 433, focusing on X-ray data observed with Suzaku at two orbital phases (in- and out-of- eclipse) and simultaneo…
