The Phase II Murchison Widefield Array: Design Overview
Randall B. Wayth, Steven J. Tingay, Cathryn M. Trott +26
We describe the motivation and design details of the "Phase II" upgrade of the Murchison Widefield Array (MWA) radio telescope. The expansion doubles to 256 the number of antenna t…
Dark-ages reionization and galaxy formation simulation - IX. Economics of reionizing galaxies
Alan R. Duffy, Simon J. Mutch, Gregory B. Poole +4
Using a series of high-resolution hydrodynamical simulations we show that during the rapid growth of high-redshift (z > 5) galaxies, reserves of molecular gas are consumed over a t…
Dark Matter Annihilation in the Circumgalactic Medium at High Redshifts
Sarah Schon, Katherine J. Mack, Stuart B. Wyithe
Annihilating dark matter (DM) models offer promising avenues for future DM detection, in particular via modification of astrophysical signals. However when modelling such potential…
Dark-ages Reionization & Galaxy Formation Simulation VIII. Suppressed growth of dark matter halos during the Epoch of Reionization
Yuxiang Qin, Alan R. Duffy, Simon J. Mutch +5
We investigate how the hydrostatic suppression of baryonic accretion affects the growth rate of dark matter halos during the Epoch of Reionization. By comparing halo properties in…
A spectroscopically confirmed z=1.327 galaxy-scale deflector magnifying a z~8 Lyman-Break galaxy in the Brightest of Reionizing Galaxies survey
R. L. Barone-Nugent, A. Sonnenfeld, J. S. B. Wyithe +6
We present a detailed analysis of an individual case of gravitational lensing of a Lyman-Break galaxy (LBG) in a blank field, identified in Hubble Space Telescope imaging…
Subtraction of point sources from interferometric radio images through an algebraic forward modeling scheme
G. Bernardi, D. A. Mitchell, S. M. Ord +4
We present a method for subtracting point sources from interferometric radio images via forward modeling of the instrument response and involving an algebraic nonlinear minimizatio…
