The black widow pulsar J1641+8049 in the optical, radio and X-rays
A. Yu. Kirichenko, S. V. Zharikov, A. V. Karpova +14
PSR J1641+8049 is a 2 ms black widow pulsar with the 2.2 h orbital period detected in the radio and -rays. We performed new phase-resolved multi-band photometry of PSR J1641+804…
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 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…
The Green Bank North Celestial Cap Survey. VIII. 21 New Pulsar Timing Solutions
William Fiore, Lina Levin, Maura A. McLaughlin +26
We present timing solutions for 21 pulsars discovered in 350 MHz surveys using the Green Bank Telescope (GBT). All were discovered in the Green Bank North Celestial Cap pulsar surv…
Searching for continuous Gravitational Waves in the second data release of the International Pulsar Timing Array
M. Falxa, S. Babak, P. T. Baker +123
The International Pulsar Timing Array 2nd data release is the combination of datasets from worldwide collaborations. In this study, we search for continuous waves: gravitational wa…
The NANOGrav Nine-Year Data Set: Excess Noise in Millisecond Pulsar Arrival Times
M. T. Lam, J. M. Cordes, S. Chatterjee +22
Gravitational wave astronomy using a pulsar timing array requires high-quality millisecond pulsars, correctable interstellar propagation delays, and high-precision measurements of…
