A Cuscuton Representation of the Loop Quantum Cosmology Bounce

Niayesh Afshordi, Kristina Giesel

Loop Quantum Cosmology (LQC) replaces the big bang singularity of the homogeneous universe by a bounce, usually described by the modified Friedmann equation $H^2=ρ(1-ρ/ρ_c)/(3M_p^2…

Self-regularized entropy: What does black hole entropy predict for tests of Kerr no-hair theorem?

Shokoufe Faraji, Niayesh Afshordi

We compute the canonical, or brick-wall, entropy of a massless scalar field in a quantum black hole model whose strong field exterior is described phenomenologically by the static…

Black hole spectroscopy: from theory to experiment

Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65

The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…

Exploring Born-Infeld f(T) teleparallel gravity through accretion disk dynamics

Ruijing Tang, Shokoufe Faraji, Niayesh Afshordi

Teleparallel Born-Infeld gravity (TBI) is a modified theory of gravity that aims to maintain second order field equations, leading to alternative scenarios for strong gravity and c…

Black Holes Inside and Out 2024: visions for the future of black hole physics

Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27

The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…
