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…

The second data release from the European Pulsar Timing Array: IV. Implications for massive black holes, dark matter and the early Universe

J. Antoniadis, P. Arumugam, S. Arumugam +111

The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and fir…

Searching for Time-Dependent Axion Dark Matter Signals in Pulsars

R. A. Battye, M. J. Keith, J. I. McDonald +3

Axion dark matter can be converted into photons in the magnetospheres of neutron stars leading to a spectral line centred on the Compton wavelength of the axion. Due to the rotatio…

European Pulsar Timing Array Limits on Continuous Gravitational Waves from Individual Supermassive Black Hole Binaries

Stanislav Babak, Antoine Petiteau, Alberto Sesana +33

We have searched for continuous gravitational wave (CGW) signals produced by individually resolvable, circular supermassive black hole binaries (SMBHBs) in the latest EPTA dataset,…

European Pulsar Timing Array Limits On An Isotropic Stochastic Gravitational-Wave Background

Lindley Lentati, Stephen R. Taylor, Chiara M. F. Mingarelli +33

We present new limits on an isotropic stochastic gravitational-wave background (GWB) using a six pulsar dataset spanning 18 yr of observations from the 2015 European Pulsar Timing…

First LOFAR observations at very low frequencies of cluster-scale non-thermal emission: the case of Abell 2256

R. J. van Weeren, H. J. A. Rottgering, D. A. Rafferty +79

Abell 2256 is one of the best known examples of a galaxy cluster hosting large-scale diffuse radio emission that is unrelated to individual galaxies. It contains both a giant radio…
