Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field (2009)
Voss, Rasmus, Gilfanov, Marat, Sivakoff, Gregory R., Kraft, Ralph P., Jordan, Andres, Raychaudhury, Somak, ...
The radial distribution of luminous L_X>10^{36} erg/s X-ray point sources in the bulge of M31 is investigated using archival Chandra observations. We find a significant increase of the specific...
Is the Lack of Pulsations in Low Mass X-Ray Binaries due to Comptonizing Coronae? (2006)
Gogus, Ersin, Alpar, M. Ali, Gilfanov, Marat
The spin periods of the neutron stars in most Low Mass X-ray Binary (LMXB) systems still remain undetected. One of the models to explain the absence of coherent pulsations has been the suppression of...
A study of the population of LMXBs in the bulge of M31 (2006)
The purpose of this study is to explore the population of X-ray point sources in the bulge of M31, with the primary goal to contrast properties of various subpopulations, such as persistent and...
Broad-band spectra of Cyg X-1 and correlations between spectral characteristics (2005)
Ibragimov, Askar, Poutanen, Juri, Gilfanov, Marat, Zdziarski, Andrzej A., Shrader, Chris R.
We present the results of spectral analysis of 42 simultaneous broad-band Ginga--OSSE and RXTE--OSSE observations of Cyg X-1 carried out in 1991 and 1996--1999. The hardest spectra in our sample in...
Correlations between X-ray and radio spectral properties of accreting black holes (2002)
Zdziarski, Andrzej A., Lubinski, Piotr, Gilfanov, Marat, Revnivtsev, Mike
We study correlations betwen X-ray spectral index, strength of Compton reflection, and X-ray and radio fluxes in accreting black holes (Seyferts and black-hole binaries). We critically evaluate the...
