4U 1624-490 as a possible intermediate-mass X-ray binary: constraints from XRISM and NuSTAR spectroscopy
R. Iaria, A. Anitra, T. Di Salvo +7
High-inclination dipping neutron-star X-ray binaries provide a direct view of accretion-flow structure because the line of sight intercepts ionised plasma above the disc. We analys…
The first IXPE view of the eclipsing ADC source 4U 1822-37
A. Anitra, A. Gnarini, T. Di Salvo +17
Accretion-disc corona sources are high-inclination low-mass X-ray binaries in which the innermost regions are hidden and the observed X-ray emission is dominated by radiation scatt…
A mysterious feature in the NICER spectrum of 4U 1820-30: A gravitationally redshifted absorption line?
R. Iaria, T. Di Salvo, A. Anitra +6
A mysterious absorption feature at approximately 3.8 keV has been identified in the NICER spectrum of the low-mass X-ray binary system 4U 1820-30. We interpret this feature as a gr…
Time domain astrophysics with transient sources. Delay estimate via Cross Correlation Function techniques
W. Leone, L. Burderi, T. di Salvo +10
The timing analysis of transient events allows for investigating numerous still open areas of modern astrophysics. The article explores all the mathematical and physical tools requ…
X-ray view of emission lines in optical spectra: Spectral analysis of the two low-mass X-ray binary systems Swift J1357.2-0933 and MAXI J1305-704
A. Anitra, C. Miceli, T. Di Salvo +6
We propose a novel approach for determining the orbital inclination of low-mass X-ray binary systems by modelling the H and H line profiles emitted by the accretion disc, wit…
X-ray and optical polarization aligned with the radio jet ejecta in GX 339-4
G. Mastroserio, B. De Marco, M. C. Baglio +27
We present the first X-ray polarization measurements of GX 339-4. IXPE observed this source twice during its 2023-2024 outburst, once in the soft-intermediate state and again durin…
The puzzling orbital residuals of XTE J1710-281: is a Jovian planet orbiting around the binary system?
R. Iaria, T. Di Salvo, A. Anitra +8
XTE J1710-281 is a transient eclipsing binary system with a period close to 3.28 hours, hosting a neutron star. The average eclipse duration is 420 seconds, and eclipse arrival tim…
Confirmation of the presence of a CRSF in the NICER spectrum of X 1822-371
R. Iaria, T. Di Salvo, A. Anitra +6
X 1822-371 is an eclipsing binary system with a period close to 5.57 hr and an orbital period derivative of 1.42(3) s s. The extremely h…
H spectroscopy of the high-inclination black hole transient Swift J1357.2-0933 during quiescence
A. Anitra, D. Mata Sanchez, T. Munoz-Darias +6
Swift J1357.2-0933 is a transient low-mass X-ray binary hosting a stellar-mass black hole. The source exhibits optical dips and very broad emission lines during both outburst and q…
