Luminous Late-time Radio Emission from Supernovae Detected by the Karl G. Jansky Very Large Array Sky Survey (VLASS)
M. C. Stroh, G. Terreran, D. L. Coppejans +10
We present a population of 19 radio-luminous supernovae (SNe) with emission reaching in the first epoch of the Very Large Array…
A new distant Giant Radio Galaxy in the Boötes field serendipitously detected by Chandra
Alberto Masini, Annalisa Celotti, Paola Grandi +2
Giant Radio Galaxies (GRGs) are the largest single structures in the Universe. Exhibiting extended radio morphology, their projected sizes range from 0.7 Mpc up to 4.9 Mpc. LOFAR h…
Reaching thermal noise at ultra-low radio frequencies: the Toothbrush radio relic downstream of the shock front
F. de Gasperin, G. Brunetti, M. Bruggen +14
Ultra-low frequency observations (<100 MHz) are particularly challenging because they are usually performed in a low signal-to-noise ratio regime due to the high sky temperature an…
A plethora of diffuse steep spectrum radio sources in Abell 2034 revealed by LOFAR
T. W. Shimwell, J. Luckin, M. Brüggen +28
With Low-Frequency Array (LOFAR) observations, we have discovered a diverse assembly of steep spectrum emission that is apparently associated with the intra cluster medium (ICM) of…
LOFAR, VLA, and Chandra observations of the Toothbrush galaxy cluster
R. J. van Weeren, G. Brunetti, M. Brüggen +39
We present deep LOFAR observations between 120-181 MHz of the "Toothbrush" (RX J0603.3+4214), a cluster that contains one of the brightest radio relic sources known. Our LOFAR obse…
