Low-frequency observations of the Giant Radio Galaxy NGC 6251
(2020-06-01)
We present LOFAR observations at 150 MHz of the borderline FRI/FRII giant radio galaxy NGC 6251. This paper presents the most sensitive and highest-resolution images of NGC 6251 at these frequencies to date, revealing for ...
Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction
(2020-02-17)
Low-frequency (ν ≲ 150 MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission from the Sun has been used to study coronal structure, ...
