Two sides of the same spin: tracking optical and radio pulsations of SAX J1808.4-3658 from outburst to quiescence
C. Ballocco, A. Miraval Zanon, A. Papitto +25
High-time-resolution optical and UV observations have revealed bright coherent pulsations from accreting millisecond pulsars, exceeding the luminosity expected from thermal emissio…
CHASE: Channel-Aligned Structure Exploitation for Geometry-Aware Model Engineering
Wei Wang, Wei Jiang, Ziran Liu
Geometric and Spectral Alignment (GSA) characterizes trained networks through spectral concentration, physical-channel alignment, support structure, and changes in singular bases.…
Searching for optical pulsations from spider millisecond pulsars with the fast photometer SiFAP2
Christian Malacaria, Alessandro Papitto, Filippo Ambrosino +19
Optical pulsations from millisecond pulsars (MSPs) have recently been detected in a transitional MSP and an accreting MSP. Evidence for optical pulsations has also been found for a…
Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…
The multiple facets of millisecond pulsar binaries
A. Miraval Zanon, G. Illiano, F. Ambrosino +17
Millisecond pulsar (MSP) binaries are unique laboratories for studying matter and radiation under extreme conditions that are unattainable on Earth. Recent detections of optical mi…
Evidence for optical pulsations from a redback millisecond pulsar
A. Papitto, F. Ambrosino, M. Burgay +16
Recent detections of optical pulsations from both a transitional and an accreting millisecond pulsar have revealed unexpectedly bright signals, suggesting that the presence of an a…
Detection of low-luminosity X-ray pulsations from the accreting millisecond pulsar IGR J17511-3057: An ever-thinning thread between bright accretion and sub-luminous states
Giulia Illiano, Alessandro Papitto, Sergio Campana +14
After nearly a decade in quiescence, the accreting millisecond pulsar IGR J175113057 displayed a new outburst on 2025 February 11, its third since discovery, following previous…
Probing multi-band variability and mode switching in the candidate transitional millisecond pulsar 3FGL J1544.6-1125
Giulia Illiano, Francesco Coti Zelati, Arianna Miraval Zanon +20
We present the most extensive high-time resolution multi-band campaign to date on the candidate transitional millisecond pulsar (tMSP) 3FGL J1544.6-1125 in the sub-luminous disk st…
A deep X-ray and UV look into the reflaring stage of the accreting millisecond pulsar SAX J1808.4-3658
Caterina Ballocco, Alessandro Papitto, Arianna Miraval Zanon +12
We present an X-ray and UV high-time-resolution monitoring of the final flaring phase of the 2022 outburst of the AMSP SAX J1808.4-3658, based on simultaneous XMM-Newton and HST ob…
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…
