The LOFAR Decametre Sky Survey (LoDeSS) I. Survey description and first data release

C. M. Cordun, C. Groeneveld, H. W. Edler +12

The decametre radio sky (- MHz) remains largely unexplored due to strong ionospheric distortions and severe radio-frequency interference. Despite its scientific potent…

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…

Joint Estimation of Properties of the Lunar Subsurface and Galactic Foregrounds with LuSEE-Night

Fatima Yousuf, Zack Li, Stuart D. Bale +36

The Lunar Surface Electromagnetics Experiment (LuSEE-Night) is a joint NASA-DOE-ESA low-frequency radio telescope that will reach the lunar far side in 2027. The unknown dielectric…

An improved algorithm for separating clock delays from ionospheric effects in radio astronomy

C. M. Cordun, M. A. Brentjens, H. K. Vedantham +1

Context: Low-frequency radio observations are heavily impacted by the ionosphere, where dispersive delays can outpace even instrumental clock offsets, posing a serious calibration…

Deep radio interferometric search for decametre radio emission from the exoplanet Tau Boötis b

C. M. Cordun, H. K. Vedantham, M. A. Brentjens +1

Detection of electron cyclotron maser (ECM) emission from exoplanets in the 10-40 MHz radio band is likely the only way to measure an exoplanet's magnetic field directly. However,…

Absorption of Millimeter-band CO and CN in the Early Universe: Molecular Clouds in Radio Galaxy B2 0902+34 at Redshift 3.4

Bjorn Emonts, Steve Curran, George Miley +9

Using the Karl G. Jansky Very Large Array (VLA), we have detected absorption lines due to carbon-monoxide, CO(J=0-1), and the cyano radical, CN(N=0-1), associated with radio galaxy…

VLBI Imaging of high-redshift galaxies and protoclusters at low radio frequencies with the International LOFAR Telescope

C. M. Cordun, R. Timmerman, G. K. Miley +4

It has long been known that luminous, ultra-steep spectrum radio sources are preferentially associated with massive galaxies at high redshifts. Here we describe a pilot project dir…
