Neutrino oscillations inside ultrarelativistic matter: on the role of the Tolman VI spacetime
Daniele Gregoris
While both neutrino propagation in photons and ultrarelativistic plasmas and neutrino oscillations in curved spacetimes have been studied extensively, their combination in a self-g…
Limits on the Inferred Hubble Constant Bias from a Local McVittie Gravitational Field
Daniele Gregoris
We examine the exact propagation of light in a McVittie spacetime to quantify the observational bias introduced on the inferred Hubble constant by a localized central mass em…
On the uniqueness of CDM-like evolution for homogeneous and isotropic cosmology in General Relativity
Saikat Chakraborty, Daniele Gregoris, B. Mishra
We address the question of the uniqueness of spatially flat CDM-like evolution for FLRW cosmologies in General Relativity, i.e. whether any model other than the spatially flat $…
On the Chandrasekhar Limit in Generalized Uncertainty Principles
Daniele Gregoris, Yen Chin Ong
The Chandrasekhar limit for white dwarfs has been confirmed by many astrophysical observations. However, how to obtain it theoretically in models which rely on other-than-Heisenber…
Understanding Gravitational Entropy of Black Holes: A New Proposal via Curvature Invariants
Daniele Gregoris, Yen Chin Ong
Partly motivated by the arrow of time problem in cosmology and the Weyl curvature hypothesis formulated by Roger Penrose, previous works in the literature have proposed - among oth…
A Critical Assessment of Black Hole Solutions With a Linear Term in Their Redshift Function
Daniele Gregoris, Yen Chin Ong, Bin Wang
Different theories of gravity can admit the same black hole solution, but the parameters usually have different physical interpretations. In this work we study in depth the linear…
