Righi, Mattia, Hernandez-Monteagudo, Carlos, Sunyaev, Rashid
The rotational lines of carbon monoxide and the fine structure lines of CII and of the most abundant metals, emitted during the epoch of enhanced star formation in the universe, are redshifted in the...
Internal shock model for Microquasars (2007)
Christian Kaiser Rashid, Christian R. Kaiser, Rashid Sunyaev, Henk C. Spruit
. We present a model for the radio outbursts of microquasars based on the assumption of quasi-continuous jet ejection. The jets are `lit up' by shock fronts traveling along the jets during...
Broad Lyman-Alpha Emission from Supernova Remnants in Young Galaxies (2007)
Charge transfer (or exchange) reactions between hydrogen atoms and protons in collisionless shocks of supernova remnants (SNRs) are a natural way of producing broad Balmer, Lyman and other lines of...
Righi, Mattia, Hernandez-Monteagudo, Carlos, Sunyaev, Rashid
Future observations of CMB anisotropies will be able to probe high multipole regions of the angular power spectrum, corresponding to a resolution of a few arcminutes. Dust emission from merging...
X-rays from cusps of compact remnants near galactic centres (2006)
Nayakshin, Sergei, Sunyaev, Rashid
Compact remnants -- stellar mass black holes and neutron stars formed in the inner few parsec of galactic centres are predicted to sink into the central parsec due to dynamical friction on low mass...
CMB and physics of the early universe (2006)
Danese, Luigi, De Zotti, Gianfranco, Lawrence, R. Charles, Longair, Malcolm, Mandolesi, Nazzareno, Novikov, Igor, ...
Nayakshin, Sergei, Sunyaev, Rashid
Few dozens of young high mass stars orbit Sgr A* at distances as short as 0.1 parsec, where star formation should be quenched by the strong tidal shear from Sgr A*. The puzzling young stellar...
On the relationship between the jets from X-ray binaries and Agn (2005)

Scattering in the vicinity of relativistic jets: a method for constraining jet parameters (2004)
Cramphorn, Conrad, Sazonov, Sergey, Sunyaev, Rashid
Relativistic jets of radio loud active galactic nuclei (AGN) produce highly directed, intense beams of radiation. A fraction of this beamed radiation scatters on the thermal plasma generally...
Cuadra, Jorge, Nayakshin, Sergei, Sunyaev, Rashid
Cold inactive disks are believed to exist in Low Luminosity AGN (LLAGN). They may also exist in the nuclei of inactive galaxies and in the center of our own Galaxy. These disks would then be embedded...
X-ray flares from Sgr A*: star-disk interactions? (2003)
Nayakshin, Sergei, Cuadra, Jorge, Sunyaev, Rashid
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 some reason....
Close stars and an inactive accretion disk in Sgr A*: Eclipses and flares (2003)
Nayakshin, Sergei, Sunyaev, Rashid
A cold neutral and extremely dim accretion disk may be present as a remnant of a past vigorous activity around the black hole in our Galactic Center (GC). Here we discuss ways to detect such a disk...

Accretion onto Black Holes and Neutron Stars: Differences and Similarities (2001)
Accreting black holes and neutron stars at luminosities above 0.01 of the critical Eddington luminosity have a lot of similarities, but also drastic differences in their radiation and power density...
Sazonov, Sergei, Sunyaev, Rashid
Measured values of the brightness temperature of low-frequency synchrotron radiation emitted by powerful extragalactic sources reach 10^11--10^12 K. If some amount of nonrelativistic ionized gas is...
Popham, Robert, Sunyaev, Rashid
We present solutions for the structure of the boundary layer where the accretion disk meets the neutron star, which is expected to be the dominant source of high-energy radiation in low-mass X-ray...
Internal shock model for Microquasars (2000)
Kaiser, Christian R., Sunyaev, Rashid, Spruit, Henk C.
We present a model for the radio outbursts of microquasars based on the assumption of quasi-continuous jet ejection. The jets are `lit up' by shock fronts traveling along the jets during outbursts....

Observations of short-duration X-ray transients by WATCH on Granat (1999)
Castro-Tirado, Alberto, Brandt, Soeren, Lund, Niels, Sunyaev, Rashid
During 1990-92, the WATCH all-sky X-ray monitor on Granat discovered six short-duration X-ray transients. In this paper we discuss their possible relationship to peculiar stars. Only one of the fast...
