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…
