Probing the environments of FRI and FRII radio galaxies in LoTSS DR2 with galaxy clusters

Tong Pan, Yuming Fu, H. J. A. Rottgering +7

The origin of the Fanaroff--Riley Class I/II (FRI/FRII) morphological dichotomy remains uncertain. We investigate whether cluster-scale environment contributes to this distinction…

Revealing the link between halo mass and radio jet activities in quasars

B. -H. Yue, P. N. Best, H. J. A. Röttgering +4

There is a fundamental lack of understanding as to why quasars that are otherwise very similar can have such a wide range of radio jet powers, and the large-scale environment is th…

Ubiquitous radio emission in quasars: predominant AGN origin and a connection to jets, dust and winds

G. Calistro-Rivera, D. M. Alexander, C. M. Harrison +16

We present a comprehensive study of the physical origin of radio emission in optical quasars at redshifts z < 2.5. We focus particularly on the associations between compact radio e…

Extragalactic Peaked-Spectrum Radio Sources at Low-Frequencies are Young Radio Galaxies

M. M. Slob, J. R. Callingham, H. J. A. Röttgering +5

We present a sample of 373 peaked-spectrum (PS) sources with spectral peaks around 150MHz, selected using a subset of two LOFAR all-sky surveys, the LOFAR Two Meter Sky Survey and…

Cosmic downsizing of powerful radio galaxies to low radio luminosities

E. E. Rigby, J. Argyle, P. N. Best +2

At bright radio powers ( W/Hz) the space density of the most powerful sources peaks at higher redshift than that of their weaker counterparts. This paper…

The shape of the radio wavefront of extensive air showers as measured with LOFAR

A. Corstanje, P. Schellart, A. Nelles +78

Extensive air showers, induced by high energy cosmic rays impinging on the Earth's atmosphere, produce radio emission that is measured with the LOFAR radio telescope. As the emissi…
