Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
F. Iraci, A. Chalumeau, C. Tiburzi +46
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…
The Chinese Pulsar Timing Array data release I. Single pulsar noise analysis
Siyuan Chen, Heng Xu, Yanjun Guo +23
The Chinese Pulsar Timing Array (CPTA) has collected observations from 57 millisecond pulsars using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) for close to th…
Rapid Construction of Joint Pulsar Timing Array Datasets: The Lite Method
Bjorn Larsen, Chiara M. F. Mingarelli, Paul T. Baker +41
The International Pulsar Timing Array (IPTA)'s second data release (IPTA DR2) combines decades of observations of 65 millisecond pulsars from 7 radio telescopes. IPTA datasets shou…
Chinese Pulsar Timing Array upper limits on microhertz gravitational waves from supermassive black-hole binaries using PSR J1713+0747 FAST data
R. Nicolas Caballero, Heng Xu, Kejia Lee +6
We derive the gravitational-wave (GW) strain upper limits from resolvable supermassive black-hole binaries using the data from the Five-hundred-meter Aperture Spherical radio Teles…
The Chinese pulsar timing array data release I. Polarimetry for 56 millisecond pulsars
Jiangwei Xu, Jinchen Jiang, Heng Xu +27
We present polarization pulse profiles for 56 millisecond pulsars (MSPs) monitored by the Chinese Pulsar Timing Array (CPTA) collaboration using the Five-hundred-meter Aperture Sph…
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…
