Published in 2020 at "Journal of Nonlinear Science"

DOI: 10.1007/s00332-019-09580-1

Abstract: We study the dynamics of many charges interacting with the Maxwell field. The particles are modeled by means of nonnegative distribution functions $$f^+$$ f + and $$f^-$$ f - representing two species of charged matter… read more here.

Published in 2019 at "Classical and Quantum Gravity"

DOI: 10.1088/1361-6382/ab0fbd

Abstract: In this paper we extend the WKB-like `non-relativistic' expansion of the minimally coupled Klein--Gordon equation after Kiefer and Singh [1], Lammerzahl [2] and Giulini and Grosardt [3] to arbitrary order in $c^{-1}$, leading to Schrodinger… read more here.

Published in 2019 at "Classical and Quantum Gravity"

DOI: 10.1088/1361-6382/ab1c53

Abstract: The advance of the pericenter of the orbit of a test body around a massive body in general relativity can be calculated in a number of ways. In one method, one studies the geodesic equation… read more here.

Published in 2020 at "Journal of Cosmology and Astroparticle Physics"

DOI: 10.1088/1475-7516/2020/12/032

Abstract: We bring together two popular formalisms which generically parameterise deviations from General Relativity on astrophysical and cosmological scales, namely the parameterised post-Newtonian (PPN) formalism and the effective field theory (EFT) of dark energy and modified… read more here.

Published in 2022 at "Journal of Cosmology and Astroparticle Physics"

DOI: 10.1088/1475-7516/2023/04/016

Abstract: Parameterised Post-Newtonian Cosmology (PPNC) is a theory-agnostic framework for testing gravity in cosmology, which connects gravitational physics on small and large scales in the Universe. It is a direct extension of the Parameterised Post-Newtonian (PPN)… read more here.

Published in 2019 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stz903

Abstract: Coalescing massive black hole binaries (MBHBs) of $10^{4-7} \rm M_{\odot}$, forming in the aftermath of galaxy mergers, are primary targets of the space mission LISA, the {\it Laser Interferometer Space Antenna}. An assessment of LISA… read more here.

Published in 2019 at "Physical Review D"

DOI: 10.1103/physrevd.100.104011

Abstract: We derive the post-Newtonian limit of a general class of teleparallel gravity theories, whose action is given by a free function of three scalar quantities obtained from the torsion of the teleparallel connection. This class… read more here.

Published in 2020 at "Physical Review D"

DOI: 10.1103/physrevd.101.084058

Abstract: We use the Effective Field Theory (EFT) framework to compute the mass quadrupole moment, the equation of motion, and the power loss of inspiralling compact binaries at the second order in the Post-Newtonian (PN) approximation.… read more here.

Published in 2022 at "Physical Review D"

DOI: 10.1103/physrevd.105.064034

Abstract: In the present paper we take a step toward the generalization of the post-Newtonian formalism to tensor-multiscalar theories. These are theories where we have more than one scalar field being mediators of the gravitational interaction… read more here.

Published in 2017 at "Physical Review D"

DOI: 10.1103/physrevd.95.124049

Abstract: We consider the parametrized post-Newtonian (PPN) limit of ghost-free massive bimetric gravity with two mutually non-interacting matter sectors coupled to the two metrics. Making use of a gauge-invariant differential decomposition of the metric perturbations, we… read more here.

Published in 2017 at "Physical Review D"

DOI: 10.1103/physrevd.96.024062

Abstract: We discuss the source of the apparent ambiguities arising in the calculation of the dynamics of binary black holes within the Post-Newtonian framework. Divergences appear in both the near and far zone calculations, and may… read more here.
