Pulsars identified in the LOFAR Two-metre Sky Survey at 144 MHz

G. A. C. Rijkers, C. G. Bassa, J. R. Callingham +1

We present the astrometric identification of 80 known radio pulsars as unresolved continuum sources detected at 144 MHz in the second data release of the LOFAR Two-metre Sky Survey…

Occurrence rate of stellar Type II radio bursts from a 100 star-year search for coronal mass ejections

David C. Konijn, Harish K. Vedantham, Cyril Tasse +8

Coronal mass ejections (CMEs) are major drivers of space weather in the Solar System, but their occurrence rate on other stars is unknown. A characteristic (deca-)metric radio burs…

Radio Burst from a Stellar Coronal Mass Ejection

J. R. Callingham, C. Tasse, R. Keers +15

Coronal mass ejections (CMEs) are massive expulsions of magnetised plasma from a star, and are the largest contributors to space weather in the Solar System. CMEs are theorized to…

Unusual periodic modulation in the radio emission of the methane dwarf binary WISEP J101905.63+652954.2

Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1

Brown dwarfs display Jupiter-like auroral phenomena, such as rotationally modulated electron cyclotron maser radio emission. Radio observations of cyclotron maser emission can be u…

Magnetic fields in planetary nebulae detected through non-thermal radio continuum emission

Marcin Hajduk, Timothy Shimwell, Glenn White +3

Context. Planetary nebulae are shells ejected by low- and intermediate-mass stars. The slow wind ejected by the asymptotic giant branch star is compressed by a fast stellar wind to…

Strongly polarised radio pulses from a new white-dwarf-hosting long-period transient

Sanne Bloot, Harish K. Vedantham, Cees G. Bassa +6

Long-period transients (LPTs) are a new and enigmatic class of objects that produce bright pulsations in the radio, with periods far exceeding those seen in rotationally powered pu…

Complex morphology and precession indicators of AGN jets in LoTSS DR2

Maya Horton, Martin Hardcastle, George Miley +2

The LOw Frequency ARray Two-metre Sky Survey second data release (LoTSS DR2) covers 27\% of the northern sky and contains around four million radio sources. The development of this…

Relighting the fire in Hickson Compact Group (HCG) 15: magnetised fossil plasma revealed by the SKA Pathfinders & Precursors

C. J. Riseley, T. Vernstrom, L. Lovisari +26

In the context of the life cycle and evolution of active galactic nuclei (AGN), the environment plays an important role. In particular, the over-dense environments of galaxy groups…

Limits and challenges of the detection of cluster-scale diffuse radio emission at high redshift: The Massive and Distant Clusters of WISE Survey (MaDCoWS) in LoTSS-DR2

G. Di Gennaro, M. Brüggen, E. Moravec +14

Diffuse radio emission in galaxy clusters is a tracer of ultra-relativistic particles and G-level magnetic fields, and is thought to be triggered by cluster merger events. In th…

PSZ2 G181.06+48.47 II: radio analysis of a low-mass cluster with exceptionally-distant radio relics

Kamlesh Rajpurohit, Andra Stroe, Ewan O'Sullivan +13

We report upgraded Giant Metrewave Radio Telescope and Karl J. Jansky Very Large Array radio observations of a low-mass merging galaxy cluster PSZ2 G181.06+48.47. This exceptional…

Non-thermal filaments and AGN recurrent activity in the galaxy group Nest200047: a LOFAR, uGMRT, MeerKAT, VLA radio spectral analysis

M. Brienza, K. Rajpurohit, E. Churazov +15

Nest200047 is a clear example of multiple radio bubbles from an Active Galactic Nucleus (AGN) in a galaxy group, featuring non-thermal filaments likely shaped by buoyancy, gas moti…

The LOFAR Two-metre Sky Survey: Deep Fields Data Release 2. I. The ELAIS-N1 field

T. W. Shimwell, C. L. Hale, P. N. Best +29

We present the final 6'' resolution data release of the ELAIS-N1 field from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey Deep Fields project (LoTSS Deep). The 144MHz images…
