The multipole moments and the tidal Love numbers of neutron stars and quark stars satisfy
certain relations which are almost insensitive to the star's internal structure. A natural …

We refine and extend a recent construction of sets of black hole microstates with
semiclassical interiors that span a Hilbert space of dimension e S, where S is the black hole …

It is now known that, apart from black holes, some naked singularities can also cast shadows
which provide their possible observable signatures. We examine the relevant question here …

We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five
dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is …

A bstract The emergence of a four-dimensional de Sitter (dS 4) universe on an expanding
bubble in the five-dimensional anti-de Sitter (AdS 5) background has been suggested as a …

It was investigated recently, with the aim of testing the weak cosmic censorship conjecture,
whether an extremal Kerr black hole can be converted into a naked singularity by interaction …

We investigate the thermodynamic equilibrium states of a rotating thin shell, ie, a ring, in a
(2+ 1)-dimensional spacetime with a negative cosmological constant. The inner and outer …

The role of angular momentum in a 2+ 1 2+ 1-dimensional rotating thin-shell wormhole
(TSW) is considered. Particular emphasis is given to stability when the shells (rings) are …

We study the geodesic motion of massive and massless test particles in the background of
equally spinning Myers–Perry–anti-de Sitter (AdS) black holes in five dimensions. By …

Gravitational collapse of matter in the presence of rotation is a mostly unexplored topic but it
might have important implications for cosmic censorship. Recently a convenient setup was …
