A LOFAR prompt search for radio emission accompanying X-ray flares in GRB 210112A
(2023-11-01)
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 distinguish these mechanisms arises because a ...
Plausible association of distant late M dwarfs with low-frequency radio emission
(2023-10-17)
We present the serendipitous discovery of eight distant (> 50 pc) late M dwarfs with plausible associated radio emission at 144 MHz. The M-dwarf nature of our sources has been confirmed with optical spectroscopy performed ...
The LOFAR Two-Metre Sky Survey : VI. Optical identifications for the second data release
(2023-10-01)
The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of ∼5700 deg1. The high angular resolution of LOFAR with Dutch baselines (6 arcsec) allows us to carry out ...
