LeMMINGs IV: The X-ray properties of a statistically-complete sample of the nuclei in active and inactive galaxies from the Palomar sample

D. R. A. Williams, M. Pahari, R. D. Baldi +22

All 280 of the statistically-complete Palomar sample of nearby (<120 Mpc) galaxies dec > 20 degrees have been observed at 1.5 GHz as part of the LeMMINGs e-MERLIN legacy survey. He…

High-resolution international LOFAR observations of 4C~43.15 -- Spectral ages and injection indices in a high-z radio galaxy

Frits Sweijen, Leah K. Morabito, Jeremy Harwood +6

Radio sources with steep spectra are preferentially associated with the most distant galaxies, the relation, but the reason for this relation is an open question. The spatial…

Unmasking the history of 3C 293 with LOFAR sub-arcsecond imaging

Pranav Kukreti, Raffaella Morganti, Timothy W. Shimwell +10

Active galactic nuclei (AGNs) show episodic activity, evident in galaxies that exhibit restarted radio jets. These restarted jets can interact with their environment, leaving signa…

Sub-arcsecond imaging with the International LOFAR Telescope: II. Completion of the LOFAR Long-Baseline Calibrator Survey

Neal Jackson, Shruti Badole, John Morgan +69

The Low-Frequency Array (LOFAR) Long-Baseline Calibrator Survey (LBCS) was conducted between 2014 and 2019 in order to obtain a set of suitable calibrators for the LOFAR array. In…
