Timing analysis of the 2022 outburst of the accreting millisecond X-ray pulsar SAX J1808.43658: hints of an orbital shrinking
Giulia Illiano, Alessandro Papitto, Andrea Sanna +19
We present a pulse timing analysis of NICER observations of the accreting millisecond X-ray pulsar SAX J1808.43658 during the outburst that started on 2022 August 19. Similar to…
Spectral analysis of the AMXP IGR J17591-2342 during its 2018 outburst
A. Manca, A. F. Gambino, A. Sanna +9
The Accreting Millisecond X-ray Pulsar IGR J17591-2342 is a LMXB system that went in outburst on August 2018 and it was monitored by the NICER observatory and partially by other fa…
ExoClock Project III: 450 new exoplanet ephemerides from ground and space observations
A. Kokori, A. Tsiaras, B. Edwards +214
The ExoClock project has been created with the aim of increasing the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides o…
Unveiling the disc structure in ultraluminous X-ray source NGC 55 ULX-1
F. Barra, C. Pinto, D. J. Walton +11
Despite two decades of studies, it is still not clear whether ULX spectral transitions are due to stochastic variability in the wind or variations in the accretion rate or in the s…
A transient ultraluminous X-ray source in NGC 55
A. Robba, C. Pinto, F. Pintore +14
Ultraluminous X-ray sources (ULXs) are a class of accreting compact objects with X-ray luminosities above 10 erg s. The average number of ULXs per galaxy is still not…
Outflows and spectral evolution in the eclipsing AMXP SWIFT J1749.4-2807 with NICER, XMM-Newton and NuSTAR
A. Marino, A. Anitra, S. M. Mazzola +18
The neutron star low-mass X-ray binary SWIFT J1749.4-2807 is the only known eclipsing accreting millisecond X-ray pulsar. In this manuscript we perform a spectral characterization…
On the peculiar long-term orbital evolution of the eclipsing accreting millisecond X-ray pulsar SWIFT J1749.4-2807
A. Sanna, L. Burderi, T. Di Salvo +15
We present the pulsar timing analysis of the accreting millisecond X-ray pulsar SWIFT J1749.4-2807 monitored by NICER and XMM-Newton during its latest outburst after almost eleven…
Investigating the nature and properties of MAXI J1810-222 with radio and X-ray observations
T. D. Russell, M. Del Santo, A. Marino +10
We present results from radio and X-ray observations of the X-ray transient MAXI J1810-222. The nature of the accretor in this source has not been identified. In this paper, we sho…
Investigating the nature of the ultraluminous X-ray sources in the galaxy NGC 925
Chiara Salvaggio, Anna Wolter, Fabio Pintore +7
Variability is a powerful tool to investigate properties of X-ray binaries (XRB), in particular for Ultraluminous X-ray sources (ULXs) that are mainly detected in the X-ray band. F…
