Constitutive Geometry of the Effective Vacuum Sector of Pseudo-Complex General Relativity
F. Weber, P. O. Hess, C. A. Zen Vasconcellos
Effective vacuum sectors in modified theories of gravity are often represented by anisotropic stress-energy tensors, even when the underlying source is geometric rather than materi…
Curvture Regularization and Dynamical Vacuum Structure in Pseudo-Complex General Relativity
Fridolin Weber, Peter Otto Hess, Cesar Augusto Zen Vasconcellos
Whether classical spacetime remains welldefined at arbitrarily high curvature is a central question. In general relativity, singularities signal the breakdown of the classical desc…
Consistent crust-core interpolation and its effect on non-radial neutron star oscillations
Martin O. Canullan-Pascual, Mauro Mariani, Ignacio F. Ranea-Sandoval +2
To model the structure of neutron stars (NSs) theoretically,it is common to consider layers with different density regimes. Matching the equation of state (EoS) for the crust and c…
Cosmic inflation in an extended non-commutative foliated quantum gravity: the wave function of the universe
César A. Zen Vasconcellos, Peter O. Hess, José de Freitas Pacheco +8
We propose a novel extension to the recently developed non-commutative Riemannian foliated branch-cut quantum gravity (BCQG). Based on an extended Faddeev-Jackiw symplectic deforma…
Strange stars admixed with mirror dark matter: confronting observations of XTE J1814-338
Shu-Hua Yang, Chun-Mei Pi, Fridolin Weber
In this paper, we explore a novel framework for explaining the mass and radius relationships of observed neutron stars by considering strange stars (SSs) admixed with mirror dark m…
Primordial gravitational waves in Wheeler-DeWitt non-commutative linearized branch-cut quantum gravity
Cesar A. Zen Vasconcellos, Peter O. Hess, Fridolin Weber +5
Branch-cut gravity (BCG) is an extended version of the ontological domain of General Relativity, which is analytically continued to the complex plane. When combined with the Hawkin…
Differential Rotation in Compact Objects with Hyperons and Delta Isobars
Delaney Farrell, Fridolin Weber, Jia Jie Li +1
Neutron stars may experience differential rotation on short, dynamical timescales following extreme astrophysical events like binary neutron star mergers. In this work, the masses…
Deducing Neutron Star Equation of State Parameters Directly From Telescope Spectra with Uncertainty-Aware Machine Learning
Delaney Farrell, Pierre Baldi, Jordan Ott +6
Neutron stars provide a unique laboratory for studying matter at extreme pressures and densities. While there is no direct way to explore their interior structure, X-rays emitted f…
