Illuminating gravitational waves: A concordant picture of photons from a neutron star merger [PDF]

Science, 2017
GROWTH observations of GW170817 The gravitational wave event GW170817 was caused by the merger of two neutron stars (see the Introduction by Smith). In three papers, teams associated with the GROWTH (Global Relay of Observatories Watching Transients ...

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays

Journal of High Energy Physics, 2021
The QCD×QED factorization is studied for two-body non-leptonic and semi-leptonic B decays with heavy-light final states. These non-leptonic decays, like B ¯ s 0 → D s + π − $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{+}{\pi}^{-} $$ and B ¯ d 0 → D + K − $$ {\

Gravitational Waves. Introduction to the Gravitational Wave Equation

, 2023
Gravitational Waves represent the transport of Gravitational Energy through Space. Equation (103) represents the “Gravitational Wave Equation”. The article presents a new theory in physics which explains the interaction between gravity and light with mathematical results close to General Relativity (15 digits beyond the decimal point equal result) and

Lunar Gravitational-wave Antenna

The Astrophysical Journal, 2021
Abstract Monitoring of vibrational eigenmodes of an elastic body excited by gravitational waves was one of the first concepts proposed for the detection of gravitational waves. At laboratory scale, these experiments became known as resonant bar detectors first developed by Joseph Weber in the 1960s.

Gravitational waves induced by scalar perturbations during a gradual transition from an early matter era to the radiation era [PDF]

Journal of Physics: Conference Series, 2019
We revisit the effects of an early matter-dominated era on gravitational waves induced by scalar perturbations. We carefully take into account the evolution of the gravitational potential, the source of these induced gravitational waves, during a gradual

Gravitational waves from first order cosmological phase transitions in the Sound Shell Model [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We calculate gravitational wave power spectra from first order early Universe phase transitions using the Sound Shell Model. The model predicts that the power spectrum depends on the mean bubble separation, the phase transition strength, the phase ...

Gravitational clock compass and the detection of gravitational waves [PDF]

Phys. Rev. D 101, 044012 (2020), 2019
We present an alternative derivation of the gravitational clock compass and show how such a device can be used for the detection of gravitational waves. Explicit compass setups are constructed in special types of space--times, namely for exact plane gravitational waves and for waves moving radially relative to an observer.

On the gauge invariance of cosmological gravitational waves [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
The issue of the gauge invariance of gravitational waves arises if they are produced in the early universe at second-order in perturbation theory. We address it by dividing the discussion in three parts: the production of gravitational waves, their ...
