Gravitational-wave cosmology across 29 decades in frequency
Paul D. Lasky, Chiara M. F. Mingarelli, Tristan L. Smith +24
Quantum fluctuations of the gravitational field in the early Universe, amplified by inflation, produce a primordial gravitational-wave background across a broad frequency band. We…
A LOFAR census of non-recycled pulsars: average profiles, dispersion measures, flux densities, and spectra
A. Bilous, V. Kondratiev, M. Kramer +24
We present first results from a LOFAR census of non-recycled pulsars. The census includes almost all such pulsars known (194 sources) at declinations and Galac…
Wide-Band, Low-Frequency Pulse Profiles of 100 Radio Pulsars with LOFAR
M. Pilia, J. W. T. Hessels, B. W. Stappers +84
LOFAR offers the unique capability of observing pulsars across the 10-240 MHz frequency range with a fractional bandwidth of roughly 50%. This spectral range is well-suited for stu…
Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays
D. R. Madison, X. -J. Zhu, G. Hobbs +23
By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…
Timing analysis for 20 millisecond pulsars in the Parkes Pulsar Timing Array
D. J. Reardon, G. Hobbs, W. Coles +18
We present timing models for 20 millisecond pulsars in the Parkes Pulsar Timing Array. The precision of the parameter measurements in these models has been improved over earlier re…
The noise properties of 42 millisecond pulsars from the European Pulsar Timing Array and their impact on gravitational wave searches
R. N. Caballero, K. J. Lee, L. Lentati +36
The sensitivity of Pulsar Timing Arrays to gravitational waves depends on the noise present in the individual pulsar timing data. Noise may be either intrinsic or extrinsic to the…
