Exploiting pulsar timing at low radio frequencies: applications to Pulsar Timing Arrays, Interstellar medium and HII regions
Pulsar timing at low radio frequencies offers a powerful way to investigate chromatic propagation effects in the ionised interstellar medium and to refine the modelling of noise processes in Pulsar Timing Array (PTA) analyses. A central element of this thesis is the combination of observations from …

Gravitational Waves in String Cosmology
… The spectrum can explain the signal measured by Pulsar Timing Arrays and a large class of models make concrete predictions for a spectral tilt in the LISA band. Our discussions provide further evidence that gravitational wave backgrounds (in particular at high frequencies) are a potential …

Studies of the Ionised Interstellar Medium at Low Radio Frequencies using LOFAR
Pulsars are observed as sources that give off rapidly pulsed radiation and as such act like precise clocks in the sky, which allow for unique experiments and discoveries. For example, the first planets ever discovered outside of the Solar system were in fact discovered around the pulsar B1257+12 as …

Gravitational waves as direct probes of binary evolution and astrophysical environments
… this dissertation, we turn our attention for pulsar timing arrays and supermassive black-hole binaries. One of the astrophysics science cases for nanohertz gravitational-wave astronomy is to determine how astrophysical environments affect supermassive black-hole binaries in their evolution …

Multidisciplinary studies of pulsar data and applications to Pulsar Timinig Arrays
Pulsars are fast-rotating, highly-magnetized neutron stars, visible at radio wavelenghts as pulsating obje ts thanks to two beams of emission that are fo ussed on the magneti poles and o-rotate with the star, the rotational axis of whi h is not aligned with the magneti one. The rotational stability …
