The LOFAR Two-metre Sky Survey -- V. Second data release

T. W. Shimwell, M. J. Hardcastle, C. Tasse +103

In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…

Alignment in the orientation of LOFAR radio sources

E. Osinga, G. K. Miley, R. J. van Weeren +7

Various studies have laid claim to finding an alignment of the polarization vectors or radio jets of active galactic nuclei (AGN) over large distances, but these results have prove…

Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction

H. K. Vedantham, J. R. Callingham, T. W. Shimwell +11

Low frequency (MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission…

Searching for the largest bound atoms in space

K. L. Emig, P. Salas, F. de Gasperin +5

(abridged) Radio recombination lines (RRLs) at frequencies < 250 MHz trace the cold, diffuse phase of the ISM. Next generation low frequency interferometers, such as LOFAR, MWA…

LOFAR early-time search for coherent radio emission from GRB 180706A

A. Rowlinson, K. Gourdji, K. van der Meulen +12

The nature of the central engines of gamma-ray bursts (GRBs) and the composition of their relativistic jets are still under debate. If the jets are Poynting flux dominated rather t…

LOFAR discovery of a radio halo in the high-redshift galaxy cluster PSZ2 G099.86+58.45

R. Cassano, A. Botteon, G. Di Gennaro +15

In this Letter, we report the discovery of a radio halo in the high-redshift galaxy cluster PSZ2 G099.86+58.45 () with the LOw Frequency ARray (LOFAR) at 120-168 MHz. This…
