Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog [PDF]

open access: yes, 2020
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the consistency of the data with predictions from the theory. We first establish

Scattering of fermions in the Yukawa theory coupled to unimodular gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We compute the lowest order gravitational UV divergent radiative corrections to the S matrix element of the $$fermion + fermion\rightarrow fermion + fermion$$ fermion+fermion→fermion+fermion scattering process in the massive Yukawa theory, coupled either

Measurement Theory and General Relativity [PDF]

open access: yes, 1998
The theory of measurement is employed to elucidate the physical basis of general relativity. For measurements involving phenomena with intrinsic length or time scales, such scales must in general be negligible compared to the (translational and ...

Wittgenstein's Thought Experiments and Relativity Theory [PDF]

open access: yes, 2019
In this paper, I discuss the similarity between Wittgenstein’s use of thought experiments and Relativity Theory. I begin with introducing Wittgenstein’s idea of “thought experiments” and a tentative classification of different kinds of thought ...

Thermodynamics: The Unique Universal Science

open access: yesEntropy, 2017
Thermodynamics is a physical branch of science that governs the thermal behavior of dynamical systems from those as simple as refrigerators to those as complex as our expanding universe.

BLACK HOLES IN THREE-DIMENSIONAL DILATON GRAVITY THEORIES [PDF]

open access: yes, 1995
Three dimensional black holes in a generalized dilaton gravity action theory are analysed. The theory is specified by two fields, the dilaton and the graviton, and two parameters, the cosmological constant and the Brans-Dicke parameter. It contains seven

Presupposition, perceptional relativity and translation theory

open access: yesRevista Alicantina de Estudios Ingleses, 2001
The intertwining of assertions and presuppositions in utterances affects the way a text is perceived in the source language (SL) and the target language (TL).

Relative morsification theory

open access: yesTopology, 2004
In this paper we develope a Morsification Theory for holomorphic functions defining a singularity of finite codimension with respect to an ideal, which recovers most previously known Morsification results for non-isolated singulatities and generalize them to a much wider context.

Deriving entangled relativity

open access: yesPhysics Letters B
Entangled Relativity is a non-linear reformulation of Einstein’s theory that cannot be defined in the absence of matter fields. It recovers General Relativity without a cosmological constant in the weak matter density limit or whenever Lm=T on-shell, and
