A NICER view of the millisecond pulsar PSR J21243358: evidence for a helium atmosphere
Denis González-Caniulef, Sebastien Guillot, Pierre Stammler +12
Pulse profile modeling has proven to be a powerful technique for determining the mass and radius of neutron stars. To date, this method has been applied to a handful of millisecond…
Inflationary interpretation of the gravitational-wave signal in the European Pulsar Timing Array DR2 with constraints
Philippe Turgeon, Chiara Caprini, Anton Chudaykin +5
The second data release of the European Pulsar Timing Array (EPTA) collaboration provides evidence for the presence of a gravitational-wave (GW) background. In this work, we explor…
On the polarization position angle jumps in FRB 20240114A
Ninisha Manaswini, Danté M. Hewitt, Laura G. Spitler +6
Fast radio bursts (FRBs), thought to originate from magnetars, exhibit diverse polarization properties that constrain their emission physics and local magneto-ionic environments. T…
Multi-wavelength emission modelling of PSR~J04374715
J. Pétri, P. Stammler, L. Guillemot +4
The diversity of pulsar light-curves and radio polarisation properties originates in the structure of the magnetic field close to the stellar surface. For millisecond pulsars, this…
Shapiro Delay Measurements from Fifteen Years of PSR J12311411 Radio Observations
H. Thankful Cromartie, Matthew Kerr, Scott M. Ransom +5
We present 15 years of Nançay and Green Bank radio telescope timing observations for PSR J12311411. This millisecond pulsar is a primary science target for the Neutron Star Int…
A NICER view of the 1.4 solar-mass edge-on pulsar PSR J0614-3329
Lucien Mauviard, Sebastien Guillot, Tuomo Salmi +20
Four neutron star radius measurements have already been obtained by modeling the X-ray pulses of rotation-powered millisecond pulsars observed by the Neutron Star Interior Composit…
