Paarl Africa Underground Laboratory (PAUL)
Robert Adam, Claire Antel, Munirat Bashir +43
Establishing a deep underground physics laboratory to study, amongst others, double beta decay, geoneutrinos, reactor neutrinos and dark matter has been discussed for more than a d…
Accretion onto deformed black holes via pseudo-Newtonian potentials
Anslyn J. John, Chris Z. Stevens
The Johannsen-Psaltis spacetime describes a rotating black hole with parametric deviations from the Kerr metric. By construction this spacetime explicitly violates the no-hair theo…
Bondi Accretion in the Spherically Symmetric Johannsen-Psaltis Spacetime
Anslyn John, Chris Stevens
The Johannsen-Psaltis spacetime explicitly violates the no hair theorem. It describes rotating black holes with scalar hair in the form of parametric deviations from the Kerr metri…
Structure formation with causal bulk viscosity
Giovanni Acquaviva, Anslyn John, Aurélie Pénin
Dissipative features of dark matter affect its clustering properties and could lead to observable consequences for the evolution of large--scale structure. We analyse the evolution…
Dark matter perturbations and viscosity: a causal approach
Giovanni Acquaviva, Anslyn John, Aurélie Pénin
The inclusion of dissipative effects in cosmic fluids modifies their clustering properties and could have observable effects on the formation of large scale structures. We analyse…
Black hole accretion in scalar-tensor-vector gravity
Anslyn J. John
We examine the accretion of matter onto a black hole in scalar--tensor--vector gravity (STVG) also known as modified gravity (MOG). The gravitational constant is …
