On the nature of the X-ray binary transient MAXI J1834-021: clues from its first observed outburst
A. Manca, A. Marino, A. Borghese +14
MAXI J1834-021 is a new X-ray transient that was discovered in February 2023. We analysed the spectral and timing properties of MAXI J1834-021 using NICER, NuStar and Swift data co…
Short-term variability of the transitional pulsar candidate CXOU J110926.4-650224 from X-rays to infrared
F. Coti Zelati, D. de Martino, V. S. Dhillon +14
CXOU J110926.4-650224 is a candidate transitional millisecond pulsar (tMSP) with X-ray and radio emission properties reminiscent of those observed in confirmed tMSPs in their X-ray…
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…
HERMES: Gamma Ray Burst and Gravitational Wave counterpart hunter
G. Ghirlanda, L. Nava, O. Salafia +67
Gamma Ray Bursts (GRBs) bridge relativistic astrophysics and multi-messenger astronomy. Space-based gamma/X-ray wide field detectors have proven essential to detect and localize th…
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…
Spectral Analysis of the LMXB XTE J1810-189 with NICER Data
A. Manca, A. Sanna, A. Marino +6
XTE J1810-189 is a Low-Mass X-ray Binary transient system hosting a neutron star, which underwent a three-month-long outburst in 2020. In order to study its spectral evolution duri…
The accretion/ejection link in the neutron star X-ray binary 4U 1820-30 I: A boundary layer-jet coupling?
A. Marino, T. D. Russell, M. Del Santo +16
The accretion flow / jet correlation in neutron star (NS) low-mass X-ray binaries (LMXBs) is far less understood when compared to black hole (BH) LMXBs. In this paper we will prese…
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…
MAXI J1957+032: a new accreting millisecond X-ray pulsar in an ultra-compact binary
A. Sanna, P. Bult, M. NG +12
The detection of coherent X-ray pulsations at ~314 Hz (3.2 ms) classifies MAXI J1957+032 as a fast-rotating, accreting neutron star. We present the temporal and spectral analysis p…
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…
