Exploring the connection between the stellar wind and the non-thermal emission in LS 5039

V. Bosch-Ramon, C. Motch, M. Ribo +5

LS 5039 has been observed with several X-ray instruments so far. The source presents X-ray variability at orbital timescales in flux and photon index. The system harbors an O-type…

4U 1344-60: a bright intermediate Seyfert galaxy at z=0.012 with a relativistic Fe Kalpha emission line

E. Piconcelli, M. Sanchez-Portal, M. Guainazzi +6

We present analysis of the optical and X-ray spectra of the low Galactic latitude bright (F(2-10) = 3.6 10^{-11} erg/cm2/s) source 4U 1344-60. On the basis of the optical data we p…

The XMM-Newton view of GRS1915+105 during a "plateau"

Andrea Martocchia, Giorgio Matt, Tomaso Belloni +3

Two XMM-Newton observations of the black-hole binary GRS1915+105 were triggered in 2004 (April 17 and 21), during a long "plateau" state of the source. We analyzed the data collect…

INTEGRAL spectroscopy of the accreting millisecond pulsar XTE J1807-294 in outburst

M. Falanga, J. M. Bonnet-Bidaud, J. Poutanen +6

The fourth transient accreting millisecond pulsar XTE J1807-294 was observed during its February/March 2003 outburst by INTEGRAL, partly simultaneously with the XMM-Newton and RXTE…
