Contemporaneous Multiwavelength and Precovery Observations of the Active Centaur P/2019 LD2 (ATLAS) Open
The Gateway Centaur and Jupiter co-orbital P/2019 LD2 (ATLAS) provides the first opportunity to observe the migration of a solar system small body from a Centaur orbit to a Jupiter Family Comet (JFC) four decades from now. The Gateway tran…

Probing ionospheric structures using the LOFAR radio telescope Open
LOFAR is the LOw‐Frequency Radio interferometer ARray located at midlatitude (52°53′N). Here we present results on ionospheric structures derived from 29 LOFAR nighttime observations during the winters of 2012/2013 and 2013/2014. We show t…

Linear polarization structures in LOFAR observations of the interstellar medium in the 3C 196 field Open
This study aims to characterize linear polarization structures in LOFAR\nobservations of the interstellar medium (ISM) in the 3C196 field, one of the\nprimary fields of the LOFAR-Epoch of Reionization key science project. We have\nused the…

Polarization leakage in epoch of reionization windows – I. Low Frequency Array observations of the 3C196 field Open
Detection of the 21-cm signal coming from the epoch of reionization (EoR) is\nchallenging especially because, even after removing the foregrounds, the\nresidual Stokes $I$ maps contain leakage from polarized emission that can mimic\nthe si…

Lunar occultation of the diffuse radio sky: LOFAR measurements between 35 and 80 MHz Open
We present radio observations of the Moon between 35 and 80 MHz to demonstrate a novel technique of interferometrically measuring large-scale diffuse emission extending far beyond the primary beam (global signal) for the first time. In par…
