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…
New supernova remnant candidates in the LOFAR Two Metre Sky Survey
K. Tsalapatas, M. Arias, T. Shimwell +3
In spite of their key role in galaxy evolution and several decades of observational efforts, the census of supernova remnants (SNRs) in our Galaxy remains incomplete. Theoretical p…

Probing particle acceleration in Abell 2256: from to 16 MHz to gamma rays
E. Osinga, R. J. van Weeren, G. Brunetti +9
Merging galaxy clusters often host spectacular diffuse radio synchrotron sources. These sources can be explained by a non-thermal pool of relativistic electrons accelerated by shoc…
The LOFAR-eFEDS survey: The incidence of radio and X-ray AGN and the disk-jet connection
Z. Igo, A. Merloni, D. Hoang +15
Radio jets are present in a diverse sample of AGN. However, the mechanisms of jet powering are not fully understood, and it is yet unclear to what extent they obey mass-invariant s…
On the Particle Acceleration Mechanisms in a Double Radio Relic Galaxy Cluster, Abell 1240
Arnab Sarkar, Felipe Andrade-Santos, Reinout J. van Weeren +12
We present a 368 ks deep Chandra observation of Abell~1240, a binary merging galaxy cluster at a redshift of 0.195 with two Brightest Cluster Galaxies (BCGs) may have passed each o…
A LOFAR prompt search for radio emission accompanying X-ray flares in GRB 210112A
A. Hennessy, R. L. C. Starling, A. Rowlinson +14
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 distingui…
A search for inter-cluster filaments with LOFAR and eROSITA
D. N. Hoang, M. Brüggen, T. W. Shimwell +13
Cosmological simulations predict the presence of warm hot thermal gas in the cosmic filaments that connect galaxy clusters. This gas is thought to constitute an important part of t…
A LOFAR sample of luminous compact sources coincident with nearby dwarf galaxies
D. Vohl, H. K. Vedantham, J. W. T. Hessels +5
The vast majority of extragalactic compact continuum radio sources are associated with star formation or jets from (super)massive black holes and, as such, are more likely to be fo…
Testing afterglow models of FRB 200428 with early post-burst observations of SGR 1935+2154
A. J. Cooper, A. Rowlinson, R. A. M. J. Wijers +8
We present LOFAR imaging observations from the April/May 2020 active episode of magnetar SGR 1935+2154. We place the earliest radio limits on persistent emission following the low-…
A deep study of A399-401: An application for wide-field facet calibration
J. M. G. H. J. de Jong, R. J. van Weeren, A. Botteon +6
We examine the particle acceleration mechanism in the Mpc-scale bridge between Abell 399 and Abell 401 and assess in particular if the synchrotron emission originates from first-or…
