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…
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…
Radio timing constraints on the orbital orientation and component masses of PSR J14553330
D. S. Pillay, V. Venkatraman Krishnan, David J. Champion +15
PSR J14553330 is a 7.98 ms pulsar in a 76.17 day nearly circular orbit with a white dwarf companion. In this work, we combine the available Lovell, Nançay decimetri…
Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21
We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…
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…
