The Rate-Controlled Constrained-Equilibrium (RCCE) method for the description of the time-dependent behavior of dynamical systems in non-equilibrium states is a general, effective, physically based method for model order reduction that was originally developed in the framework of thermodynamics and chemical kinetics. A generalized mathematical formulation is presented here that allows including...

The gravitational waves emitted during the coalescence of binary black holes are an excellent probe to test behaviour strong gravity. In this paper, we propose a new called `merger-ringdown consistency test` that focuses on probing imprints dynamics in strong-gravity around black-holes plunge-merger and ringdown phase. Furthermore, present scheme allows us efficiently combine information across...

Abstract In cosmology, the fine-structure constant can affect whole ionization history. However, previous works confine themselves to recombination epoch and give various strong constraints on constant. this paper, we also take reionization into consideration do a consistency test of from From data combination Planck 2018, BAO data, SNIa samples, SFR density UV IR measurements, Q HII constraint...

We find an analytic asymptotically anti-de Sitter solution for charged rotating black strings in Einsteinian quartic gravity. By studying the near-horizon behavior of solutions, we independently extract their thermodynamic properties, analytically. As a consistency check, show that first law thermodynamics holds exactly both and uncharged cases.
