PublicaciónMass estimates from optical modelling of the new TRAPUM redback PSR J1910-5320
Spider pulsars continue to provide promising candidates for neutron star mass measurements. Here we present the discovery of PSR J1910-5320, a new millisecond...

PublicaciónMatter ejections behind the highs and lows of the transitional millisecond pulsar PSR J1023+0038
Transitional millisecond pulsars are an emerging class of sources that link low-mass X-ray binaries to millisecond radio pulsars in binary systems. These...

PublicaciónMeasuring the mass of the black widow PSR J1555-2908
Accurate measurements of the masses of neutron stars are necessary to test binary evolution models, and to constrain the neutron star equation of state. In...

PublicaciónMultiband study of RX J0838-2827 and XMM J083850.4-282759: a new asynchronous magnetic cataclysmic variable and a candidate transitional millisecond pulsar
In a search for the counterpart to the Fermi-LAT source 3FGL J0838.8-2829, we performed a multiwavelength campaign: in the X-ray band with Swift and XMM-Newton...
