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 impact on astrometry by solar-wind effect in pulsar timing
K. Liu, A. Parthasarathy, M. Keith +16
Astrometry of pulsars, particularly their distances, serves as a critical input for various astrophysical experiments using pulsars. Pulsar timing is a primary approach for determi…

Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
