CMB Observations and the Production of Chemical Elements at the End of the Dark Ages
K. Basu, C. Hernandez-Monteagudo, R. Sunyaev
The metallicity evolution and ionization history of the universe must leave its imprint on the Cosmic Microwave Background through resonant scattering of CMB photons by atoms, ions…
Statistical properties of the combined emission of a population of discrete sources: astrophysical implications
M. Gilfanov, H-J. Grimm, R. Sunyaev
We study the statistical properties of the combined emission of a population of discrete sources (e.g. X-ray emission of a galaxy due to its X-ray binaries population). Namely, we…
On the Detectability of Turbulence and Bulk Flows in X-ray Clusters
Rashid A. Sunyaev, Michael L. Norman, Greg L. Bryan
Cooling flows, cluster mergers and motions of galaxies through the cluster gas with supersonic and sonic velocities must lead to large scale motions of the intracluster medium (ICM…
First hours of the GRB 030329 optical afterglow
R. A. Burenin, R. A. Sunyaev, M. N. Pavlinsky +12
We present the first results of the observations of the extremely bright optical afterglow of gamma-ray burst (GRB) 030329 with the 1.5m Russian-Turkish telescope RTT150 (TUBITAK N…
The spectrum of the cosmic X-ray background observed by RTXE/PCA
M. Revnivtsev, M. Gilfanov, R. Sunyaev +2
We have analyzed a large set of RXTE/PCA scanning and slewing observations performed between April 1996 and March 1999. We obtained the 3-20 keV spectrum of the cosmic X-ray backgr…
The Non-Linear Dependence of Flux on Black Hole Mass and Accretion Rate in Core Dominated Jets
S. Heinz, R. Sunyaev
We derive the non-linear relation between the core flux F_{nu} of accretion powered jets at a given frequency and the mass M of the central compact object. For scale invariant jet…
Review of low-mass X-ray binaries near the Galactic center
A. Lutovinov, S. Grebenev, S. Molkov +1
Results of observations of several LMXBs in the Galactic center region carried out with the ART-P telescope on board \Granat observatory are briefly reviewed. More than dozen sourc…
X-ray flares from Sgr A*: star-disk interactions?
Sergei Nayakshin, Jorge Cuadra, Rashid Sunyaev
Sgr A*, the putative black hole in our Galactic Center (GC), is extraordinary dim in all frequencies. Apparently the black hole is unable to accrete at the Bondi accretion rate for…
