Spectral analysis of LMC X-2 with XMM/Newton: unveiling the emission process in the extragalactic Z-source
G. Lavagetto, R. Iaria, A. D'Ai' +2
We present the results of the analysis of an archival observation of LMC X-2 performed with XMM/Newton. The spectra taken by high-precision instruments have never been analyzed bef…
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,…
Broad-band Spectral Evolution of Scorpius X-1 along its Color-Color Diagram
A. D'Aí, P. Zycki, T. Di Salvo +3
We analyze a large collection of RXTE archive data from April 1997 to August 2003 of the bright X-ray source Scorpius X-1 in order to study the broadband spectral evolution of the…
Chandra Observation of the Big Dipper X 1624-490
R. Iaria, G. Lavagetto, A. D'Ai' +2
We present the results of a 73 ks long Chandra observation of the dipping source X 1624-490. During the observation a complex dip lasting 4 hours is observed. We analyse the persis…
