The LOFAR Decametre Sky Survey (LoDeSS) I. Survey description and first data release
C. M. Cordun, C. Groeneveld, H. W. Edler +12
The decametre radio sky (- MHz) remains largely unexplored due to strong ionospheric distortions and severe radio-frequency interference. Despite its scientific potent…
ViCTORIA project: A pilot study of the M49 region in the Virgo cluster in polarisation
A. Spasic, A. Benati, M. Brüggen +7
Large-scale magnetic fields permeate the Intracluster Medium (ICM) of galaxy clusters. Understanding these fields gives an insight into the origin of cosmic magnetic fields and the…
The Cosmic Ray Life Cycle in Galaxy Clusters
Francesco de Gasperin, Marcus Brüggen, Henrik Edler +3
Within the cosmic web, gravitational energy, linked to the formation and growth of the Universe's largest structures and the activity of active galactic nuclei (AGN), is converted…
Exploring the physics of ram pressure stripping with radio continuum observations in the SKA era
Alessandro Ignesti, Ian D. Roberts, Henrik W. Edler +4
Satellite galaxies in clusters are significantly more likely to be red and passive than similar mass galaxies in the field. This fact is known as the environmental quenching of gal…

ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…
Nearby galaxies in the LOFAR Two-metre Sky Survey IV. A fundamental plane of the radio-SFR relation
V. Heesen, H. W. Edler, M. Brüggen +7
Radio continuum emission has the potential to be an extinction-free tracer of star formation. However, the relation between radio continuum luminosity and star formation rate, the…
Multi-wavelength insights into the pulsar wind nebula candidate near 1LHAASO J0343+5254u: an obscured merging galaxy cluster?
H. W. Edler, M. Arias, A. Botteon +1
The advent of the Large High Altitude Air Shower Observatory (LHAASO) accelerated the detection of TeV and PeV gamma-ray sources. Some of these are associated with pulsar wind nebu…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
The longest known tails of ram-pressure-stripped star-forming galaxies are caused by an intracluster medium shock in Abell 1367
H. W. Edler, M. Hoeft, S. Bhagat +10
The environment plays an important role in shaping the evolution of cluster galaxies through mechanisms such as ram pressure stripping (RPS), whose effect may be enhanced in mergin…
LOFAR 58 MHz Legacy Survey of the 3CRR Catalog
J. M. Boxelaar, F. De Gasperin, M. J. Hardcastle +4
The Low Frequency Array (LOFAR) is uniquely able to perform deep, 15" resolutions imaging at frequencies below 100 MHz. Observations in this regime, using the Low Band Antenna (LBA…
Simulating realistic radio continuum survey maps with diffusion models
Tobias Vičánek Martínez, Henrik W. Edler, Marcus Brüggen
The next generation of radio surveys is going to be transformative for cosmology and other aspects of our understanding of astrophysics. Realistic simulations of radio observations…
A view of the CIZA J2242.8+5301 galaxy cluster at very low radio frequencies
G. Lusetti, M. Brüggen, H. W. Edler +9
The galaxy cluster CIZA J2242.8+5301 is a well-studied merging galaxy cluster that hosts prominent double radio relics including the famous sausage relic, as well as other diffuse…
The low-frequency flattening of the radio spectrum of giant HII regions in M 101
L. Gajović, V. Heesen, M. Brüggen +10
In galaxies, the flattening of the spectrum at low radio frequencies below 300 MHz has been the subject of some debate. A turnover at low frequencies could be caused by multiple ph…
The ViCTORIA project: description of a multi-frequency radio survey of the Virgo galaxy cluster
F. de Gasperin, H. W. Edler, A. Boselli +8
The Virgo cluster is the closest richest nearby galaxy cluster. It is in the formation process, with a number of sub-clusters undergoing merging and interactions. Although a great…
Ultra-low frequency LOFAR spectral indices of cluster radio halos
T. Pasini, F. de Gasperin, M. Brüggen +11
A fraction of galaxy clusters harbor diffuse radio sources known as radio halos. The currently adopted scenario for their formation is based on second-order Fermi re-acceleration o…
A 100 kpc Ram Pressure Tail Trailing the Group Galaxy NGC 2276
I. D. Roberts, R. J. van Weeren, F. de Gasperin +5
