New supernova remnant candidates in the LOFAR Two Metre Sky Survey
K. Tsalapatas, M. Arias, T. Shimwell +3
In spite of their key role in galaxy evolution and several decades of observational efforts, the census of supernova remnants (SNRs) in our Galaxy remains incomplete. Theoretical p…
Subarcsecond view on the high-redshift blazar GB 1508+5714 by the International LOFAR Telescope
A. Kappes, P. R. Burd, M. Kadler +14
Studies of the most distant AGNs allow us to test our current understanding of the physics present in radio-jetted AGNs across a range of environments. The decrease in apparent lum…
Limits on long-time-scale radio transients at 150 MHz using the TGSS ADR1 and LoTSS DR2 catalogues
Iris de Ruiter, Guillaume Leseigneur, Antonia Rowlinson +4
We present a search for transient radio sources on timescales of 2 to 9 yr at 150 MHz. This search is conducted by comparing the first Alternative Data Release of the TIFR GMRT Sky…
Hard X-ray selected giant radio galaxies -- III. The LOFAR view
G. Bruni, M. Brienza, F. Panessa +12
Giant radio galaxies (GRGs), with extended structures reaching hundreds of kpc, are among the most spectacular examples of ejection of relativistic plasma from super-massive black…
LOFAR Detection of a Low-Power Radio Halo in the Galaxy Cluster Abell 990
N. D. Hoang, T. W. Shimwell, E. Osinga +10
Radio halos are extended (), steep-spectrum sources found in the central region of dynamically disturbed clusters of galaxies. Only a handful of radio halos have bee…
New mysteries and challenges from the Toothbrush relic: wideband observations from 550 MHz to 8 GHz
K. Rajpurohit, M. Hoeft, F. Vazza +10
Radio relics are diffuse extended synchrotron sources that originate from shock fronts induced by galaxy cluster mergers. The actual particle acceleration mechanism at the shock fr…
