Periodicities in radio emissions from the Jupiter's magnetosphere and consequences for radio emissions from star-exoplanet systems
C. K. Louis, A. Loh, P. Zarka +7
The search for radio signals from exoplanets or star-planet interactions is a topic of major scientific interest, as it is likely the best way to detect and measure a planetary mag…
Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
F. Iraci, A. Chalumeau, C. Tiburzi +46
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…
A circularly polarized low-frequency radio burst from the exoplanetary system HD 189733
X. Zhang, P. Zarka, J. N. Girard +17
We aim to detect low-frequency radio emission from exoplanetary systems, which can provide insights into planetary magnetic fields, star-planet interactions, stellar activity, and…
Broadband Polarized Radio Emission Detected from Starlink Satellites Below 100 MHz with NenuFAR
X. Zhang, P. Zarka, C. Viou +16
This study evaluates the impact of Starlink satellites on low-frequency radio astronomy below 100 MHz, focusing on challenges on data processing and scientific goals. We conducted…
Near-field imaging of local interference in radio interferometric data: Impact on the redshifted 21 cm power spectrum
S. Munshi, F. G. Mertens, L. V. E. Koopmans +24
Radio-frequency interference (RFI) is a major systematic limitation in radio astronomy, particularly for science cases requiring high sensitivity, such as 21 cm cosmology. Traditio…
