Unifying the Dark Sector with the New Generalized Chaplygin Gas: Observational Constraints
Abdulla Al Mamon, Andronikos Paliathanasis, Subhajit Saha
In light of recent cosmological observations, we examine a generalized Chaplygin gas model with a redshift-dependent exponent as a framework for describing the dark energy and dark…
Eccentricity evolution consistency test to distinguish eccentric gravitational-wave signals from eccentricity mimickers
Sajad A. Bhat, Avinash Tiwari, Md Arif Shaikh +1
Eccentric compact binary coalescences (CBCs) are expected to be observed in current and future gravitational-wave (GW) detector networks. However, it has been recently pointed out…
Defining eccentricity for spin-precessing binaries
Md Arif Shaikh, Vijay Varma, Antoni Ramos-Buades +4
Standardizing the definition of eccentricity is necessary for unambiguous inference of the orbital eccentricity of compact binaries from gravitational wave observations. In previou…
The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…
Interacting tachyon with varying mass dark matter
Goutam Mandal, Sudip Mishra, Abdulla Al Mamon +1
This paper presents an investigation of cosmological dynamics of tachyon fluid coupled to varyingmass dark matter particles in the background of spatially flat FLRW universe. The m…
Dynamical systems analysis of an interacting scalar field model in an anisotropic universe
Sujoy Bhanja, Goutam Mandal, Abdulla Al Mamon +1
In this paper, we investigate a non-canonical scalar field model in the background dynamics of anisotropic Locally Rotationally Symmetric (LRS) Bianchi type I universe where gravit…
