A LOFAR prompt search for radio emission accompanying X-ray flares in GRB 210112A
A. Hennessy, R. L. C. Starling, A. Rowlinson +14
The composition of relativistic gamma-ray burst (GRB) jets and their emission mechanisms are still debated, and they could be matter or magnetically dominated. One way to distingui…

A. J. Goodwin, K. D. Alexander, J. C. A. Miller-Jones +12
A tidal disruption event (TDE) occurs when a star is destroyed by a supermassive black hole. Broadband radio spectral observations of TDEs trace the emission from any outflows or j…

Multiwavelength Scrutiny of X-ray Sources in Dwarf Galaxies: ULXs versus AGN
Erica Thygesen, Richard M. Plotkin, Roberto Soria +10
Owing to their quiet evolutionary histories, nearby dwarf galaxies (stellar masses ) have the potential to teach us about the mechanism(s) t…
