The Variability of Radio Stars
Laura N. Driessen, Alex Andersson, Joseph R. Callingham +6
Stellar radio emission is highly variable with stellar flares lasting from milliseconds to hours. For some stars, their flares or bursts can repeat once every couple of hours, whil…
FRB 20250316A: A Brilliant and Nearby One-Off Fast Radio Burst Localized to 13 parsec Precision
FRB Collaboration, Thomas C. Abbott, Daniel Amouyal +83
Precise localizations of a small number of repeating fast radio bursts (FRBs) using very long baseline interferometry (VLBI) have enabled multiwavelength follow-up observations rev…

B. K. Gehlot, L. V. E. Koopmans, S. A. Brackenhoff +13
Measurement of the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn (CD) and Epoch of Reionisation (EoR) promises to unveil a wealth of information about the astrop…
The unseen host galaxy and high dispersion measure of a precisely-localised Fast Radio Burst suggests a high-redshift origin
Lachlan Marnoch, Stuart D. Ryder, Clancy W. James +13
FRB 20210912A is a fast radio burst (FRB), detected and localised to sub-arcsecond precision by the Australian Square Kilometre Array Pathfinder. No host galaxy has been identified…
Searching for the sources of excess extragalactic dispersion of FRBs
Sunil Simha, Khee-Gan Lee, J. Xavier Prochaska +11
The FLIMFLAM survey is collecting spectroscopic data of field galaxies near fast radio burst (FRB) sightlines to constrain key parameters describing the distribution of matter in t…
21 new long-term variables in the GX 339-4 field: two years of MeerKAT monitoring
L. N. Driessen, B. W. Stappers, E. Tremou +14
We present 21 new long-term variable radio sources found commensally in two years of weekly MeerKAT monitoring of the low-mass X-ray binary GX 339-4. The new sources vary on time s…
Asymmetric mass ratios for bright double neutron-star mergers
R. D. Ferdman, P. C. C. Freire, B. B. P. Perera +11
The discovery of a radioactively powered kilonova associated with the binary neutron star merger GW170817 was the first - and still only - confirmed electromagnetic counterpart to…
Modelling and peeling extended sources with shapelets: a Fornax A case study
J. L. B. Line, D. A. Mitchell, B. Pindor +6
To make a power spectrum (PS) detection of the 21 cm signal from the Epoch of Reionisation (EoR), one must avoid/subtract bright foreground sources. Sources such as Fornax A presen…
Murchison Widefield Array and XMM-Newton observations of the Galactic supernova remnant G5.9+3.1
D. Onić, M. D. Filipović, I. Bojičić +27
In this paper we discuss the radio continuum and X-ray properties of the so-far poorly studied Galactic supernova remnant (SNR) G5.9+3.1. We present the radio spectral energy distr…
Constraining very-high-energy and optical emission from FRB 121102 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +155
Fast radio bursts (FRBs) are bright flashes observed typically at GHz frequencies with millisecond duration, whose origin is likely extragalactic. Their nature remains mysterious,…
Interplanetary Scintillation studies with the Murchison Wide-field Array II: Properties of sub-arcsecond compact sources at low radio frequencies
R. Chhetri, J. Morgan, R. D. Ekers +5
We report the first astrophysical application of the technique of wide-field Interplanetary Scintillation (IPS) with the Murchison Widefield Array (MWA). This powerful technique al…
A large light-mass component of cosmic rays at 10^{17} - 10^{17.5} eV from radio observations
S. Buitink, A. Corstanje, H. Falcke +101
Cosmic rays are the highest energy particles found in nature. Measurements of the mass composition of cosmic rays between 10^{17} eV and 10^{18} eV are essential to understand whet…
What are the megahertz peaked-spectrum sources?
Rocco Coppejans, David Cseh, Sjoert van Velzen +8
Megahertz peaked-spectrum (MPS) sources have spectra that peak at frequencies below 1 GHz in the observer's frame and are believed to be radio-loud active galactic nuclei (AGN). We…
On the protection of extrasolar Earth-like planets around K/M stars against galactic cosmic rays
J. -M. Grießmeier, A. Stadelmann, J. L. Grenfell +2
Previous studies have shown that extrasolar Earth-like planets in close-in habitable zones around M-stars are weakly protected against galactic cosmic rays (GCRs), leading to a str…
