3D particle-in-cell simulations of pulsar wind-disk interaction: application to the transitional millisecond pulsar PSR J1023+0038
Valentina Richard-Romei, Benoît Cerutti, Alessandro Papitto +1
Transitional millisecond pulsars constitute a peculiar subclass of neutron stars in which the pulsar alternates between accretion-powered and rotation-powered states, depending on…
Gravitational self-lensing of Fast Radio Bursts in neutron star magnetospheres: II. Applications to strong repeaters and the CHIME population
Riccardo La Placa, Simone Dall'Osso, Luigi Stella +1
Paper I in this series introduced a model in which seed radio bursts produced by a hotspot anchored in the magnetosphere of a highly-magnetic neutron star (NS) are greatly amplifie…
A semi-coherent search for optical pulsations from Scorpius X-1
Riccardo La Placa, Alessandro Papitto, Giulia Illiano +14
The emission of continuous gravitational waves (CWs) possibly explains why pulsars spinning with a period shorter than a millisecond have not been observed so far. Neutron stars ac…
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…
An ultraviolet burst oscillation candidate from the low-mass X-ray binary EXO 0748-676
A. Miraval Zanon, F. Ambrosino, G. Illiano +15
X-ray burst oscillations are quasi-coherent periodic signals at frequencies close to the neutron star spin frequency. They are observed during thermonuclear Type I X-ray bursts fro…
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…
