A possible cyclotron resonance scattering feature near 0.7 keV in X1822-371
R. Iaria, T. Di Salvo, M. Matranga +9
We analyse all available X-ray observations of X1822-371 made with XMM-Newton, Chandra, Suzaku and INTEGRAL satellites. The observations were not simultaneous. The Suzaku and INTEG…
Suzaku broad-band spectrum of 4U 1705-44: Probing the Reflection component in the hard state
T. Di Salvo, R. Iaria, M. Matranga +7
Iron emission lines at 6.4-6.97 keV, identified with Kalpha radiative transitions, are among the strongest discrete features in the X-ray band. These are one of the most powerful p…
Testing Rate Dependent corrections on timing mode EPIC-pn spectra of the accreting Neutron Star GX 13+1
F. Pintore, A. Sanna, T. di Salvo +6
When the EPIC-pn instrument on board XMM-Newton is operated in Timing mode, high count rates (>100 cts/s) of bright sources may affect the calibration of the energy scale, resultin…
Chandra X-ray spectroscopy of a clear dip in GX 13+1
A. D'Aì, R. Iaria, T. Di Salvo +3
The source GX 13+1 is a persistent, bright Galactic X-ray binary hosting an accreting neutron star. It shows highly ionized absorption features, with a blueshift of 400 km s…
Discovery of periodic dips in the light curve of GX 13+1: the X-ray orbital ephemeris of the source
R. Iaria, T. Di Salvo, L. Burderi +3
The bright low-mass X-ray binary (LMXB) GX 13+1 is one of the most peculiar Galactic binary systems. A periodicity of 24.27 d with a formal statistical error of 0.03 d was observed…
Testing reflection features in 4U 1705-44 with XMM-Newton, BeppoSAX and RXTE in the hard and soft state
E. Egron, T. Di Salvo, S. Motta +10
We use data of the bright atoll source 4U 1705-44 taken with XMM-Newton, BeppoSAX and RXTE both in the hard and in the soft state to perform a self-consistent study of the reflecti…
X-ray spectroscopy of the ADC source X1822-371 with Chandra and XMM-Newton
R. Iaria, T. Di Salvo, A. D'Aì +5
The eclipsing low-mass X-ray binary X1822-371 is the prototype of the accretion disc corona (ADC) sources. We analyse two Chandra observations and one XMM-Newton observation to stu…
Evidence for a resonant cyclotron line in IGR J16493-4348 from the Swift-BAT hard X-ray survey
A. D'Aì, G. Cusumano, V. La Parola +4
Resonant absorption cyclotron features are a key diagnostic tool to directly measure the strength of the magnetic field of accreting neutron stars. However, typical values for cycl…
Detailed study of the X-ray and Optical/UV orbital ephemeris of X1822-371
R. Iaria, T. Di Salvo, L. Burderi +4
Recent studies of the optical/UV and X-ray ephemerides of X1822-371 have found some discrepancies in the value of the orbital period derivative. Because of the importance of this v…
Subarcsecond location of IGR J17480-2446 with Rossi XTE
A. Riggio, L. Burderi, T. Di Salvo +10
On 2010 October 13, the X-ray astronomical satellite Rossi XTE, during the observation of the newly discovered accretion powered X-ray pulsar IGR J17480--2446, detected a lunar occ…
A relativistic iron emission line from the neutron star low-mass X-ray binary GX 3+1
S. Piraino, A. Santangelo, P. Kaaret +7
We present the results of a spectroscopic study of the Fe Kα emission of the persistent neutron-star atoll low-mass X-ray binary and type I X-ray burster GX 3+1 with the EPIC-PN on…
A complete X-ray spectral coverage of the 2010 May-June outbursts of Circinus X-1
A. D'Aì, E. Bozzo, A. Papitto +6
Circinus X-1 is a neutron-star-accreting X-ray binary in a wide (P = 16.6 d), eccentric orbit. After two years of relatively low X-ray luminosity, in May 2010 Circinus…
The Swift-BAT survey reveals the orbital period of three high-mass X-ray binaries
A. D'Aì, V. La Parola, G. Cusumano +4
A growing number of previously hidden Galactic X-ray sources are now detected with recent surveys performed by the Integral and Swift satellites. Most of these new sources eluded p…
A self-consistent approach to the hard and soft states of 4U 1705-44
A. D'Aì, T. Di Salvo, D. Ballantyne +10
We analyzed two XMM-Newton observations of the bright atoll source 4U 1705-44, which can be considered a prototype of the class of the persistent NS LMXBs showing both hard and sof…
