Exploring the Galactic plasma with pulsars in the SKA Era

Caterina Tiburzi, M. T. Lam, D. J. Reardon +17

The ionised media that permeate the Milky Way have been active topics of research since the discovery of pulsars in 1967. In fact, pulsars allow one to study several aspects of sai…

The SKAO Pulsar Timing Array

Ryan M. Shannon, N. D. Ramesh Bhat, Aurélien Chalumeau +22

Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…

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…

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…

Pulsar timing methods for evaluating dispersion measure time series

F. Iraci, A. Chalumeau, C. Tiburzi +9

Radio pulsars allow the study of the ionised interstellar medium and its dispersive effects, a major noise source in gravitational wave searches using pulsars. In this paper, we co…

Exploring the time variability of the Solar Wind using LOFAR pulsar data

S. C. Susarla, A. Chalumeau, C. Tiburzi +22

High-precision pulsar timing is highly dependent on precise and accurate modeling of any effects that impact the data. It was shown that commonly used Solar Wind models do not accu…

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…

The second data release from the European Pulsar Timing Array I. The dataset and timing analysis

J. Antoniadis, S. Babak, A. -S. Bak Nielsen +66

Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1 - 100 nanohertz), which is intimately connected to a number of markers that can uniquely trac…
