The NANOGrav 11-Year Data Set: Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries

K. Aggarwal, Z. Arzoumanian, P. T. Baker +60

Observations indicate that nearly all galaxies contain supermassive black holes (SMBHs) at their centers. When galaxies merge, their component black holes form SMBH binaries (SMBHB…

The NANOGrav 11-year Data Set: Pulse Profile Variability

P. R. Brook, A. Karastergiou, M. A. McLaughlin +30

Access to 50 years of data has led to the discovery of pulsar emission and rotation variability on timescales of months and years. Most of this long-term variability has been seen…

Parkes Pulsar Timing Array constraints on ultralight scalar-field dark matter

Nataliya K. Porayko, Xingjiang Zhu, Yuri Levin +27

It is widely accepted that dark matter contributes about a quarter of the critical mass-energy density in our Universe. The nature of dark matter is currently unknown, with the mas…

Studying the solar system with the International Pulsar Timing Array

R. N. Caballero, Y. J. Guo, K. J. Lee +77

Pulsar-timing analyses are sensitive to errors in the solar-system ephemerides (SSEs) that timing models utilise to estimate the location of the solar-system barycentre, the quasi-…

The NANOGrav 12.5-Year Data Set: The Frequency Dependence of Pulse Jitter in Precision Millisecond Pulsars

M. T. Lam, M. A. McLaughlin, Z. Arzoumanian +25

Low-frequency gravitational-wave experiments require the highest timing precision from an array of the most stable millisecond pulsars. Several known sources of noise on short time…

PSR J2234+0611: A new laboratory for stellar evolution

K. Stovall, P. C. C. Freire, J. Antoniadis +30

We report timing results for PSR J2234+0611, a 3.6-ms pulsar in a 32-day, eccentric (e = 0.13) orbit with a helium white dwarf companion discovered as part of the Arecibo Observato…
