Empirical determination of the Galactic neutron star--black hole merger rate using StarTrack models

Terrence Pierre Jacques, D. R. Lorimer, Nihan Pol +2

The discovery of a pulsar in a binary system with a black hole would provide a unique laboratory for testing general relativity in the strong-field regime and offer vital constrain…

Comparing recent PTA results on the nanohertz stochastic gravitational wave background

The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242

The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…

Reciprocating Magnetic Fields in the Pulsar Wind Observed from the Black Widow Pulsar J1720-0534

Chen-Chen Miao, Victoria Blackmon, Wei-Wei Zhu +41

We report the radio observations of the eclipsing black widow pulsar J1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 M. We obtain t…

The NANOGrav 12.5-Year Data Set: Dispersion Measure Mis-Estimation with Varying Bandwidths

Sofia Valentina Sosa Fiscella, Michael T. Lam, Zaven Arzoumanian +28

Noise characterization for pulsar-timing applications accounts for interstellar dispersion by assuming a known frequency-dependence of the delay it introduces in the times of arriv…

The NANOGrav 12.5-year Data Set: Search for Gravitational Wave Memory

Gabriella Agazie, Zaven Arzoumanian, Paul T. Baker +87

We present the results of a Bayesian search for gravitational wave (GW) memory in the NANOGrav 12.5-yr data set. We find no convincing evidence for any gravitational wave memory si…

The NANOGrav 15-year Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational Wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111

The NANOGrav 15-year data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gr…
