Cosmological Evolution of Primordial Black Holes: UV/IR Decoupling and the KM3NeT 220 PeV Neutrino Anomaly
Debdatta Dey, Tausif Parvez, S. Shankaranarayanan
The recent observation of a 220 PeV neutrino event (KM3-230213A) by the KM3NeT observatory presents a formidable challenge to standard astrophysical source models. We investigate t…
Exact, non-singular black holes from a phantom DBI Field as primordial dark matter
Tausif Parvez, S. Shankaranarayanan
We present the first exact, non-singular black hole solution in General Relativity sourced by a Dirac-Born-Infeld (DBI) scalar field. Crucially, the solution is exclusively support…
Quantum signatures in black hole accretion: Pair production in dynamical magnetic fields
Susobhan Mandal, Tausif Parvez, S. Shankaranarayanan
Accretion disks around black holes host extreme conditions where general relativity and magnetohydrodynamics dominate. These disks exhibit two distinct dynamical regimes -- Standar…
From Horndeski action to the Callan-Giddings-Harvey-Strominger model and beyond
Susobhan Mandal, Tausif Parvez, S. Shankaranarayanan
The knowledge of what entered black hole (BH) is completely lost as it evaporates. This contradicts the unitarity principle of quantum mechanics and is referred to as the informati…
