Characterizing Signal Loss in the 21 cm Reionization Power Spectrum: A Revised Study of PAPER-64

Carina Cheng, Aaron R. Parsons, Matthew Kolopanis +18

The Epoch of Reionization (EoR) is an uncharted era in our Universe's history during which the birth of the first stars and galaxies led to the ionization of neutral hydrogen in th…

Radio Galaxy Detection in the Visibility Domain

Adam Malyali, Marzia Rivi, Filipe B. Abdalla +1

We explore a new Bayesian method of detecting galaxies from radio interferometric data of the faint sky. Working in the Fourier domain, we fit a single, parameterised galaxy model…

Deep Learning Based Detection of Cosmological Diffuse Radio Sources

Claudio Gheller, Franco Vazza, Annalisa Bonafede

In this paper we introduce a reliable, fully automated and fast algorithm to detect extended extragalactic radio sources (cluster of galaxies, filaments) in existing and forthcomin…

Calibration of AGILE-GRID with on-ground data and Monte Carlo simulations

P. W. Cattaneo, A. Rappoldi, A. Argan +41

AGILE is a mission of the Italian Space Agency (ASI) Scientific Program dedicated to gamma-ray astrophysics, operating in a low Earth orbit since April 23, 2007. It is designed to…

Radio Galaxy Shape Measurement with Hamiltonian Monte Carlo in the Visibility Domain

M. Rivi, M. Lochner, S. T. Balan +2

Radio weak lensing, while a highly promising complementary probe to optical weak lensing, will require incredible precision in the measurement of galaxy shape parameters. In this p…

Radio transients investigation with VLBI

K. V. Sokolovsky, M. Giroletti, S. Corbel +2

The technique of Very Long Baseline Interferometry (VLBI) can provide accurate localization and unique physical information about radio transients. However, it is still underutiliz…

Redundant interferometric calibration as a complex optimization problem

T. L. Grobler, G. Bernardi, J. S. Kenyon +2

Observations of the redshifted 21-cm line from the epoch of reionization have recently motivated the construction of low frequency radio arrays with highly redundant configurations…

The HERA-19 Commissioning Array: Direction Dependent Effects

Saul A. Kohn, James E. Aguirre, Paul La Plante +64

Foreground power dominates the measurements of interferometers that seek a statistical detection of highly-redshifted HI emission from the Epoch of Reionization (EoR). The chromati…
