A simple proof of exponential decay in the two dimensional percolation model
Yu Zhang
Kesten showed the exponential decay of percolation probability in the subcritical phase for the two-dimensional percolation model. This result implies his celebrated computation th…
Estimating the Spins of Stellar-Mass Black Holes by Fitting Their Continuum Spectra
Ramesh Narayan, Jeffrey E. McClintock, Rebecca Shafee
We have used the Novikov-Thorne thin disk model to fit the continuum X-ray spectra of three transient black hole X-ray binaries in the thermal state. From the fits we estimate the…
Dynamics of Magnetized Spherical Accretion Flows
Roman V. Shcherbakov
Transonic accretion flow with self-consistent treatment of random magnetic field is presented.
Recycling Matter in the Universe. X-ray observations of SBS 1150+599A (PN G135.9+55.9)
Gagik Tovmassian, John Tomsick, Ralf Napiwotzki +4
We present X-ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM-Newton satellite. Only one component of the binary can be obse…
Radio and gamma-ray emissions from pulsars: possible observational tests
G. J. Qiao, K. J. Lee, H. G. Wang +2
Many models for the pulsar radio and -ray emissions have been developed. The tests for these models using observational data are very important. Tests for the pulsar radio emiss…
A complex environment around Cir X-1
A. D'Ai, R. Iaria, T. Di Salvo +2
We present the results of an archival 54 ks long Chandra observation of the peculiar source Cir X--1 during the phase passage 0.223-0.261. A comparative analysis of X-ray spectra,…
