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…

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…

Long term monitoring of FRB~20121102 with the Nançay Radio Telescope and multi-wavelength campaigns including INTEGRAL

C. Gouiffés, C. Ng, I. Cognard +12

The origin(s) of Fast Radio Bursts (FRBs), mysterious radio bursts coming from extragalactic distances, remains unknown. Multi-wavelength observations are arguably the only way to…
