Polarized multiwavelength emission from pulsar wind - accretion disk interaction in a transitional millisecond pulsar
M. C. Baglio, F. Coti Zelati, A. Di Marco +17
Transitional millisecond pulsars (tMSPs) bridge the evolutionary gap between accreting neutron stars in low-mass X-ray binaries and millisecond radio pulsars. These systems exhibit…
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…
Discovery of Polarized X-Ray Emission from the Accreting Millisecond Pulsar SRGA J144459.2-604207
Alessandro Papitto, Alessandro Di Marco, Juri Poutanen +22
We report on the discovery of polarized X-ray emission from an accreting millisecond pulsar. During a 10-day-long coverage of the February 2024 outburst of SRGA J144459.2-604207, t…
Spying on the quickly variable optical sky with the fast optical photometer SiFAP2
Giulia Illiano, Alessandro Papitto, Filippo Ambrosino +3
The development of detectors with a high time resolution has been pivotal to our comprehension of neutron stars and the accurate measurement of their properties. While high-time re…
NICER Discovery that SRGA J144459.2-604207 is an Accreting Millisecond X-ray Pulsar
Mason Ng, Paul S. Ray, Andrea Sanna +17
We present the discovery, with the Neutron Star Interior Composition Explorer (NICER), that SRGA J144459.2-604207 is a 447.9 Hz accreting millisecond X-ray pulsar (AMXP), which und…
