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…

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…

Magnetar Fireballs and Short Bursts: Curved Spacetime Lensing, QED Effects, Spectra, Polarization, and Impulse Responses

Zorawar Wadiasingh, Hoa Dinh Thi, Constantinos Kalapotharakos +12

Magnetar short bursts (SBs) are hard X-ray transients of durations s peaking at keV, and are prime targets for new high-energy missions and polarimeters. The…

The first IXPE view of the eclipsing ADC source 4U 1822-37

A. Anitra, A. Gnarini, T. Di Salvo +17

Accretion-disc corona sources are high-inclination low-mass X-ray binaries in which the innermost regions are hidden and the observed X-ray emission is dominated by radiation scatt…
