We present a catalogue of over 7000 sources from the GLEAM survey which have significant structure on sub-arcsecond scales at 162MHz. The compact nature these was detected and quantified via their Interplanetary Scintillation (IPS) signature, measured in interferometric images Murchison Widefield Array. advantage this approach is that all sufficiently across area are included down to well-defin...

The high surface-brightness sensitivity of the galactic and extragalactic all-sky mwa survey (GLEAM) image giant radio galaxy (GRG) 0503-28 at 70–230 MHz has revealed an inversion-symmetric bending its two lobes, while maintaining a ∼200 kpc wide strip-like emission gap between their bent portions. This lends source appearance mega-sized X-shaped galaxy. Identifying with presence gaseous layer,...

Abstract Motivated by the desire for wide-field images with well-defined statistical properties 21 cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator sky using interferometric measurement equation. We demonstrate this “direct mapping” data from Hydrogen Epoch of Reionization (HERA) Phase I observations. After validating simulated data, develop fi...

A t the dawn of the twentyfirst century, young adult literature looks very different than it did fifty years ago. Indeed, fifty years ago, we were just getting started with the likes of Salinger’s The Catcher In The Rye (1951), with Hinton’s The Outsiders (1967), Zindel’s The Pigman (1968), and Cormier’s The Choco­ late War (1974) still a gleam in the eye of their literary creators. We have a c...

Determining the number of cases in an epidemic is fundamental to properly evaluate several disease features of high relevance for public health policies such as mortality, morbidity or hospitalization rates. Surveillance efforts are however incomplete especially at the early stage of an outbreak due to the ongoing learning process about the disease characteristics. An example of this is represe...

ABSTRACT We present a broad-band map of polarized diffuse emission at 167–198 MHz developed from data the Murchison Widefield Array (MWA). The is designed to improve visibility simulation and precision calibration for 21 cm Epoch Reionization (EoR) experiments. It covers large swath – 11 000 sq. deg. Southern hemisphere sky in all four Stokes parameters captures on angular scales 1–9°. band-ave...

Accurate groundwater level (GWL) prediction is essential for the sustainable management of resources. However, GWLs remains a challenge due to insufficient data and complicated hydrogeological system. In this study, we investigated ability Gravity Recovery Climate Experiment (GRACE) satellite data, Global Land Evaporation Amsterdam Model (GLEAM) Data Assimilation System (GLDAS) publicly availab...
