A recent study of dissipative collapse considered a contracting sphere in which the areal and proper radii are equal throughout its evolution. The in…

Lovelock gravity consisting of the dimensionally continued Euler densities is a natural generalization of general relativity to higher dimensions suc…

We investigate a compact spherically symmetric relativistic body with anisotropic particle pressure profiles. The distribution possesses characterist…

We analyse the impact of the inverse square law fall-off of the energy density in a charged isotropic spherically symmetric fluid. Initially we impos…

Amongst a number of modified theories of gravity, the Rastall theory has been propounded to address some shortcomings of the standard theory of gener…

We present a catalog of 182 galaxy clusters detected through the Sunyaev-Zel'dovich effect by the Atacama Cosmology Telescope in a contiguous 987.5 d…

The isiZulu verb is known for its morphological complexity, which is a subject for on-going linguistics research, as well as for prospects of computa…

Lensing peaks have been proposed as a useful statistic, containing cosmological information from non-Gaussianities that is inaccessible from traditio…

We present an exact static, spherically symmetric black hole solution to the third order Lovelock gravity with a string cloud background in seven dim…

We examine the effects of the Rastall parameter on the behaviour of spherically symmetric static distributions of perfect fluid matter. It was claime…

The not necessarily unitary evolution operator of a finite dimensional quantum system is studied with the help of a projection operators technique. A…

We are grateful to Barun Pal for useful discussions. AR acknowledges the Council of Scientific and Industrial Research (CSIR), India for financial support (Grant award no. 20-6/2008(II)E.U.-IV).

The Bipolar Spherical Harmonics (BipoSH) form a natural basis to study the CMB two point correlation function in a non-statistically isotropic (non-S…

The primordial non-Gaussianity induces scale-dependent bias of the \hi with respect to the underlying dark matter, which exhibits features on the ver…

We present an implementation scheme for a quantum walk in the orbital angular momentum space of a laser beam. The scheme makes use of a ring interfer…

We optimise the parameters of the Population Monte Carlo algorithm using numerical simulations. The optimisation is based on an efficiency statistic …

We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the clus…

IsiZulu is one of the eleven official languages of South Africa and roughly half the population can speak it. It is the first (home) language for ove…

Quantum non-Markovianity of a quantum noisy channel manifests typically as information backflow, characterized by the departure of the intermediate m…

The population of fast radio bursts (FRBs) will continue to diverge into two groups depending on their method of discovery: those which can be locali…

We make use of wavelet transform to study the multi-scale, self similar behavior and deviations thereof, in the stock prices of large companies, belo…
