Reconstruction of spider system’s observables from orbital-period modulations via the Applegate mechanism Open
Redback and black-widow pulsars are two classes of peculiar binary systems characterised by very short orbital periods, very low-mass companions, and, in several cases, regular eclipses in their pulsed radio signal. Long-term timing reveal…

Non-locality in quadrupolar gravitational radiation Open
General Relativity suffers for two main problems which have not yet been overcome: it predicts spacetime singularities and cannot be formulated as a perturbative renormalizable theory. In particular, many attempts have been made for avoidi…

Towards an exact approach to pulsar timing Open
The pulsar timing technique, which compares the observed arrival times of electromagnetic radiation from a pulsar with the predicted arrival times derived from a theoretical model of the pulsar system, is used in pulsar astronomy to infer …

Constraints on non-local gravity from binary pulsars gravitational emission Open
Non-local theories of gravity are considered extended theories of gravity, meaning that when the non-local terms are canceled out, the limit of General Relativity (GR) is obtained. Several reasons have led us to consider this theory with i…

A soft and transient ultraluminous X-ray source with six-hour modulation in the NGC 300 galaxy Open
We investigate the nature of CXOU J005440.5−374320 (J0054), a peculiar bright (∼4 × 10 39 erg s −1 ) and soft X-ray transient in the spiral galaxy NGC 300 with a six-hour periodic flux modulation that was detected in a 2014 Chandra observa…

The effect of environment in the timing of a pulsar orbiting SgrA* Open
Pulsars are rapidly rotating neutron stars emitting intense electromagnetic radiation that is detected on Earth as regular and precisely timed pulses. By exploiting their extreme regularity and comparing the real arrival times with a theor…

Non‐Linear Electrodynamics in Blandford–Znajek Energy Extraction Open
Non‐linear electrodynamics (NLED) is a generalization of Maxwell's electrodynamics for strong fields. It has significant implications for the study of black holes and cosmology and has been extensively studied in the literature, extending …

Energy extraction via magnetic reconnection in Lorentz breaking Kerr–Sen and Kiselev black holes Open
Black holes can accumulate a large amount of energy, responsible for highly energetic astrophysical phenomena. Although the Blandford–Znajek is considered to date the leading mechanism for powering jets and GRBs, recently fast magnetic rec…
