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…
Time lags as proxy of spectral evolution in gamma-ray bursts
C. Maraventano, F. Daigne, R. Mochkovitch +3
Positive lags in gamma-ray bursts (GRBs), where hard photons anticipate softer ones, provide a unique window into the temporal evolution of their prompt emission. Negative lags, wh…
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…
High energy time lags of Gamma Ray Bursts
C. Maraventano, G. Ghirlanda, L. Nava +5
Positive lags between the arrival time of different photon energies are commonly observed in Gamma-Ray Bursts (GRBs), where soft photons lag behind harder ones. However, some GRBs…
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…
