Assessing ionospheric effects on image quality in the LOFAR Decametre Sky Survey
Cristina-Maria Cordun, Harish K. Vedantham, Maaijke Mevius
The terrestrial ionosphere is a major limitation for high angular resolution imaging at decametre wavelengths. Its rapidly varying and direction-dependent phase errors can defocus…
The impact of lunar topography on the 21-cm power spectrum for grid-based arrays : Insights for the Dark-ages EXplorer (DEX)
S. Ghosh, L. V. E. Koopmans, C. Brinkerink +17
The Dark Ages (DA) provides a crucial window into the physics of the infant Universe, with the 21-cm signal offering the only direct probe for mapping out the three-dimensional dis…
Linear map-making with LuSEE-Night
Hugo Camacho, Kaja M. Rotermund, Anže Slosar +32
LuSEE-Night is a pathfinder radio telescope on the lunar far side employing four 3-m monopole antennas arranged as two horizontal cross pseudo-dipoles on a rotational stage and sen…
Peering into the Dark (Ages) with Low-Frequency Space Interferometers
Leon Koopmans, Rennan Barkana, Mark Bentum +28
Neutral hydrogen pervades the infant Universe, and its redshifted 21-cm signal allows one to chart the Universe. This signal allows one to probe astrophysical processes such as the…
Discovering the Sky at the Longest Wavelengths with Small Satellite Constellations
Xuelei Chen, Jack Burns, Leon Koopmans +29
Due to ionosphere absorption and the interference by natural and artificial radio emissions, ground observation of the sky at the decameter or longer is very difficult. This unexpl…
DSA-10: A Prototype Array for Localizing Fast Radio Bursts
J. Kocz, V. Ravi, M. Catha +8
The Deep Synoptic Array 10 dish prototype is an instrument designed to detect and localise fast radio bursts with arcsecond accuracy in real time. Deployed at Owens Valley Radio Ob…
