Due to ionosphere absorption and the interference of natural and artificial radio emissions,
astronomical observation from the ground becomes very difficult at the wavelengths of …

The number of small satellites has grown hugely in the past decade, from tens of satellites
per year in the mid-2010s to a projection of tens of thousands in orbit by the mid-2020s. This …

The past two decades have witnessed a renewed interest in low frequency radio astronomy,
with a particular focus on frequencies above 30 MHz eg, LOFAR (LOw Frequency ARray) in …

In this work, we study the luminosity that results from the conversion of QCD axion particles
into photons in the magnetic field of the plasma accreting onto black holes (BHs). For the …

Solar type III radio bursts are the most common impulsive radio signatures from the Sun,
stimulated by electron beams traveling through the solar corona and solar wind. Type III …

A bstract In this paper we examine the possibility of dilute axion stars converting to photons
in the weak, large-scale magnetic field of the Milky Way and show that they can resonate …

Due to ionosphere absorption and the interference by natural and artificial radio emissions,
ground observation of the sky at the decameter or longer is very difficult. This unexplored …

Primordial black hole production in the mass range is motivated respectively by
interpretations of the LIGO/Virgo observations of binary black hole mergers and by their …

This paper reports a design study for a space-based decametric wavelength telescope.
While not a new concept, this design study focused on many of the operational aspects that …

Low-frequency radio interferometry is crucial to understanding the universe and its very
early days. Unfortunately, most of the current instruments are ground-based and thus …
