Direct constraints on ultra-light boson mass from searches for continuous gravitational waves

Timelike Geodesics in Naked Singularity and Black Hole Spacetimes II

We plot the orbit equations and find the Perihelion precession of the orbits of particles in the BST and JNW spacetimes and compare these with the Schwarzschild black hole spacetime. Expand abstract.

Emergent Black Hole Dynamics in Critical Floquet Systems

Beyond a time scale determined by the inverse Hawking temperature, excitations are absorbed by the black holes resulting in a singular concentration of energy at their center. Expand abstract.

Induced Spins from Scattering Experiments of Initially Nonspinning Black Holes

When two relativistically boosted, nonspinning black holes pass by one another on a scattering trajectory, we might expect the tidal interaction to spin up each black hole. Expand abstract.

Linearized Stability of Bardeen de-Sitter Thin-Shell Wormholes

A thin-shell wormhole is crafted by the cut-and-paste method of two Bardeen de-Sitter black holes using Darmois-Israel formalism. Expand abstract.

Separability of the Klein-Gordon equation for rotating spacetimes obtained from Newman-Janis algorithm

In the literature, the Newman-Janis algorithm (NJA) has been widely used to construct stationary and axisymmetric spacetimes to describe rotating black holes. Expand abstract.

Does black-hole growth depend fundamentally on host-galaxy compactness?

Possible connections between central black-hole (BH) growth and host-galaxy compactness have been found observationally, which may provide insight into BH-galaxy coevolution: compact galaxies might have large amounts of gas in their centers due to their high mass-to-size ratios, and simulations predict that high central gas density can boost BH accretion.

Searching for Eccentricity: Signatures of Dynamical Formation in the First Gravitational-Wave Transient Catalogue of LIGO and Virgo

Binary black holes are thought to form primarily via two channels: isolated evolution and dynamical formation. Expand abstract.

GUP black hole remnants in quadratic gravity

The Hawking flux is shown to vanish for small black holes, for a precise combination of the GUP parameter and the coupling constants that drive the gravitational interaction in quadratic gravity, yielding absolutely stable black hole remnants. Expand abstract.

Black holes in the low mass gap: Implications for gravitational wave observations

Binary neutron-star mergers will predominantly produce black-hole remnants of mass $\sim 3$--$4\,M_{\odot}$, thus populating the putative \emph{low mass gap} between neutron stars and stellar-mass black holes. Expand abstract.
