Quark-Novae, cosmic reionization, and early r-process element production
R. Ouyed, R. E. Pudritz, P. Jaikumar
We examine the case for Quark-Novae (QNe) as possible sources for the reionization and early metal enrichment of the universe. Quark-Novae are predicted to arise from the explosive…
Science with ASKAP - the Australian Square Kilometre Array Pathfinder
S. Johnston, R. Taylor, M. Bailes +47
[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be…
Three-Dimensional Simulations of Magnetized Superbubbles: New Insights into the Importance of MHD Effects on Observed Quantities
J. M. Stil, N. D. Wityk, R. Ouyed +1
We present three-dimensional magnetohydrodynamic (MHD) simulations of superbubbles, to study the importance of MHD effects in the interpretation of images from recent surveys of th…
A three stage model for the inner engine of GRBs: Prompt emission and early afterglow
Jan Staff, Brian Niebergal, Rachid Ouyed
We describe a model within the ``Quark-nova'' scenario to interpret the recent observations of early X-ray afterglows of long Gamma-Ray Bursts (GRB) with the Swift satellite. This…
The Distance of the SNR Kes 75 and PWN PSR J1846-0258 System
Denis A. Leahy, Wenwu Tian
The supernova remnant (SNR) Kes 75/PSR J1846-0258 association can be regarded as certain due to the accurate location of young PSR J1846-0258 at the center of Kes 75 and the detect…
Birth rates of SGRs and AXPs: delayed amplification of magnetic field
Denis Leahy, Rachid Ouyed
We present new determination of the birth rate of AXPs and SGRS and their associated SNRs. We find a high birth rate of 1/(500 yr) for AXPs/SGRs and 1/(1700 yr) for associated SNRs…
