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…

Periodicity search in the timing of the 25 millisecond pulsars from the second data release of the European Pulsar Timing Array

Iuliana Nitu, Michael Keith, David Champion +17

In this work, we investigated the presence of strictly periodic, as well as quasi-periodic signals, in the timing of the 25 millisecond pulsars from the EPTA DR2 dataset. This is e…

A Gaussian-processes approach to fitting for time-variable spherical solar wind in pulsar timing data

Iuliana C. Niţu, Michael J. Keith, Caterina Tiburzi +26

Propagation effects are one of the main sources of noise in high-precision pulsar timing. For pulsars below an ecliptic latitude of , the ionised plasma in the solar wind…
