Angular function for the Compton scattering in mildly and ultra relativistic astrophysical plasmas
Sergei Y. Sazonov, Rashid A. Sunyaev
Compton scattering of low-frequency radiation by an isotropic distribution of (i) mildly and (ii) ultra relativistic electrons is considered. It is shown that the ensemble-averaged…
Backward asymmetry of the Compton scattering by an isotropic distribution of relativistic electrons: astrophysical implications
Sergei Y. Sazonov, Rashid A. Sunyaev
The angular distribution of low-frequency radiation after single scattering by an isotropic distribution of relativistic electrons considerably differs from the Rayleigh angular fu…
Spread of Matter Over a Neutron-Star Surface During Disk Accretion
N. A. Inogamov, R. A. Sunyaev
Disk accretion onto a slowly rotating neutron star with a weak magnetic field gauss is considered in a wide range of luminosities where…
Microwave polarization in the direction of galaxy clusters induced by the CMB quadrupole anisotropy
S. Y. Sazonov, R. A. Sunyaev
Electron scattering induces a polarization in the cosmic microwave background (CMB) signal measured in the direction of a galaxy cluster due to the presence of a quadrupole compone…
Long-Term Variability of the Hard X-ray Source GRS 1758-258: GRANAT/SIGMA Observations
S. I. Kuznetsov, M. R. Gilfanov, E. M. Churazov +13
The results of GRANAT/SIGMA hard X-ray observations of GRS 1758-258 in 1990-1998 are presented. The source lies at ~5\arcdeg from the Galactic Center and was within the SIGMA field…
GRANAT/ART-P observations of GX3+1: type I X-ray burst and persistent emission
S. V. Molkov, S. A. Grebenev, M. N. Pavlinsky +1
We present results of observations of the known LMXB source GX3+1 with the telescope ART-P on board GRANAT in the fall of 1990. A strong X-ray burst was detected from the source on…
The X-ray Nova GRS 1739-278 near the Galactic Center
K. N. Borozdin, M. G. Revnivtsev, S. P. Trudolyubov +3
The soft X-ray nova GRS 1739-278 flared up in 1996 near the Galactic center. We present the observations of this interesting source, a black-hole candidate, with the instruments on…
