Mass ratio in SS433 revisited [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We revisit the determination of binary mass ratio in the Galactic microquasar SS433 based on recent GRAVITY VLTI measurements of mass and angular momentum outflow through a circumbinary disc. The new observations combined with the constancy of the binary

The refractory-to-ice mass ratio in comets [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We review the complex relationship between the dust-to-gas mass ratio usually estimated in the material lost by comets, and the Refractory-to-Ice mass ratio inside the nucleus, which constrains the origin of comets.

Frozen up dilaton and the GUT/Planck mass ratio
Physics Letters B, 2017 By treating modulus and phase on equal footing, as prescribed by Dirac, local scale invariance can consistently accompany any Brans–Dicke ω-theory. We show that in the presence of a soft scale symmetry breaking term, the classical solution, if it exists,

Detecting Massive Scalar Fields with Extreme Mass-Ratio Inspirals. [PDF]
Physical Review Letters, 2022 We study the imprint of light scalar fields on gravitational waves from extreme mass-ratio inspirals-binary systems with a very large mass asymmetry. We first show that, to leading order in the mass ratio, any effects of the scalar on the waveform are ...

Targeted large mass ratio numerical relativity surrogate waveform model for GW190814 [PDF]
Physical Review D, 2022 Gravitational wave observations of large mass ratio compact binary mergers like GW190814 highlight the need for reliable, high-accuracy waveform templates for such systems.

Detecting electric charge with extreme mass ratio inspirals [PDF]
Physical Review D, 2022 . We consider extreme mass ratio inspirals during which an electrically charged compact object with mass m p and the charge to mass ratio q inspirals around a Schwarzschild black hole of mass M .

Detecting fundamental fields with LISA observations of gravitational waves from extreme mass-ratio inspirals [PDF]
Nature Astronomy, 2021 The Laser Interferometer Space Antenna1, LISA, will detect gravitational wave signals from extreme mass-ratio inspirals2, where a stellar mass compact object orbits a supermassive black hole and eventually plunges into it.

Fast extreme-mass-ratio-inspiral waveforms: New tools for millihertz gravitational-wave data analysis [PDF]
Physical Review D, 2021 We present the FastEMRIWaveforms (FEW) package, a collection of tools to build and analyze extreme mass ratio inspiral (EMRI) waveforms. Here, we expand on the Physical Review Letter that introduced the first fast and accurate fully-relativistic EMRI ...

Gravitational-Wave Energy Flux for Compact Binaries through Second Order in the Mass Ratio. [PDF]
Physical Review Letters, 2021 Within the framework of self-force theory, we compute the gravitational-wave energy flux through second order in the mass ratio for compact binaries in quasicircular orbits.
