Observations of the redshifted 21-cm line of atomic hydrogen have provided several upper
limits on the 21-cm power spectrum and a tentative detection of the sky-averaged signal at …

In the most distant reaches of the Universe, the 21 cm hyperfine transition in neutral
hydrogen provides one of the only available tracers of large-scale structure. A number of …

The present study aims at characterizing the habitability conditions of exoplanets with an
Earth‐like magnetosphere inside the habitable zone of M and F stars, caused by the direct …

Studying the magnetic fields of exoplanets will provide valuable information about their
interior structures, atmospheric properties (escape and dynamics), and potential habitability …

Magnetic interactions between stars and close-in planets may lead to a detectable signal on
the stellar disc. HD 189733 is one of the key exosystems thought to harbour magnetic …

While the Bbb Z 3 symmetric dark matter models have shown tremendous prospects in
addressing a number of (astro-) particle physics problems, they can leave interesting …

We investigate the beaming of 11 Io‐Jupiter decametric (Io‐DAM) emissions observed by
Juno/Waves, the Nançay Decameter Array, and NenuFAR. Using an up‐to‐date magnetic …

Context. The Fermi Large Area Telescope has detected over 260 gamma-ray pulsars. About
one quarter of these are labeled as radio-quiet, that is they either have radio flux densities< …

In the past two decades, it has been convincingly argued that magnetospheric radio
emissions, of cyclotron maser origin, can occur for exoplanetary systems, similarly as solar …

This work is concerned with a detailed study of an active antenna, which can serve as a
prototype of a phased array antenna element for a future lunar very-low-frequency (VLF) …
