The expulsion and retention of dust grains by galactic discs

, 1998
We have constructed a numerical model of a galaxy that consists of a stellar, gas and dust disc imbedded within a dark halo. We have used this model to assess the radiation, gravitational and viscous forces on dust grains and to trace their motion ...

A White-Lentz Hybrid Warp Drive Solution: Towards The Theoretical Feasibility of Intergalactic Travel

This paper proposes a unified theoretical framework for intergalactic travel within a single human lifetime, combining matter-antimatter propulsion, Penrose Process energy extraction from a rotating black hole, and a novel hybrid synthesis of Harold White's warp drive optimization methodology with Erik Lentz's positive-energy soliton geometry, herein ...

The Arrival Direction Distribution of Extremely High Energy Cosmic Rays Observed by AGASA

, 2003
Study of the arrival direction distribution plays a key role in finding sources of the Extremely High Energy Cosmic Rays (EHECR). Greisen-Zatsepin-Kuz'min (GZK) mechanism limits the propagation of EHE cosmic rays significantly and only nearby sources can

Studies of the intergalactic medium during the Epoch of Reionization : Understanding observational probes with simulations

The first billion years of the Universe is a unique era, marked by the formation of the first stars, galaxies, and accreting black holes, which release ionising radiation into the intergalactic medium (IGM). As a result, these luminous sources initiate a

Position-dependent power spectra of the 21-cm signal from the epoch of reionization

, 2019
The 21-cm signal from the epoch of reionization is non-Gaussian. Current radio telescopes are focused on detecting the 21-cm power spectrum, but in the future the Square Kilometre Array is anticipated to provide a first measurement of the bispectrum ...
