AMUSE-antlia I: Nuclear X-ray properties of early-type galaxies in a dynamically young galaxy cluster
Zhensong Hu, Yuanyuan Su, Zhiyuan Li +14
To understand the formation and growth of supermassive black holes (SMBHs) and their co-evolution with host galaxies, it is essential to know the impact of environment on the activ…
Low-frequency observations of the Giant Radio Galaxy NGC 6251
T. M. Cantwell, J. D. Bray, J. H. Croston +22
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…
The LOFAR view of NGC 3998, a sputtering AGN
Sarrvesh S. Sridhar, Raffaella Morganti, Kristina Nyland +3
Low-power radio sources dominate the radio sky. They tend to be small in size and core-dominated, but the origin of their properties and the evolution of their radio plasma are not…
Warped diffusive radio halo around the quiescent spiral edge-on galaxy NGC 4565
V. Heesen, L. Whitler, P. Schmidt +12
Cosmic rays play a pivotal role in launching galactic winds, particularly in quiescently star-forming galaxies where the hot gas alone is not sufficient to drive a wind. Except for…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
The POlarised GLEAM Survey (POGS) I: First Results from a Low-Frequency Radio Linear Polarisation Survey of the Southern Sky
C. J. Riseley, E. Lenc, C. L. Van Eck +7
The low-frequency polarisation properties of radio sources are poorly studied, particularly in statistical samples. However, the new generation of low-frequency telescopes, such as…
LOFAR MSSS: Flattening low-frequency radio continuum spectra of nearby galaxies
K. T. Chyży, W. Jurusik, J. Piotrowska +35
The shape of low-frequency radio continuum spectra of normal galaxies is not well understood, the key question being the role of physical processes such as thermal absorption in sh…
Reliable detection and characterization of low-frequency polarized sources in the LOFAR M51 field
A. Neld, C. Horellou, D. D. Mulcahy +14
The new generation of broad-band radio continuum surveys will provide large data sets with polarization information. New algorithms need to be developed to extract reliable catalog…
LOFAR MSSS: The Scaling Relation between AGN Cavity Power and Radio Luminosity at Low Radio Frequencies
G. Kokotanekov, M. Wise, G. H. Heald +35
We present a new analysis of the widely used relation between cavity power and radio luminosity in clusters of galaxies with evidence for strong AGN feedback. We study the correlat…
LOFAR MSSS: Discovery of a 2.56 Mpc giant radio galaxy associated with a disturbed galaxy group
A. O. Clarke, G. Heald, T. Jarrett +40
We report on the discovery in the LOFAR Multifrequency Snapshot Sky Survey (MSSS) of a giant radio galaxy (GRG) with a projected size of Mpc projected on the sky. I…
Faraday tomography of the local interstellar medium with LOFAR: Galactic foregrounds towards IC342
C. L. Van Eck, M. Haverkorn, M. I. R. Alves +18
The new generation of low-frequency radio telescopes, such as the Low Frequency Array (LOFAR: a Square Kilometre Array-low pathfinder), provides advancements in our capability of p…
Magnetic fields on a wide range of scales in star-forming galaxies
George Heald, Anna Williams, Sarrvesh S. Sridhar
A key ingredient in the evolution of galaxies is the star formation cycle. Recent progress in the study of magnetic fields is revealing the close connection between star formation…
