Revealing the intricacies of radio galaxies and filaments in the merging galaxy cluster Abell 2255. II. Properties of filaments using multi-frequency radio data
E. De Rubeis, M. Bondi, A. Botteon +11
In this paper, we aim to further analyze the filaments in Abell 2255 combining LOFAR data with uGMRT (1260 MHz) and VLA (1520 MHz) data to constrain the spectral shape of the filam…
The high-redshift radio galaxy 3C 294 at low frequencies: radio detection of the X-ray Ghost
Vijay H. Mahatma, Andrew C. Fabian, Leah K. Morabito
We report on the very first radio detection associated with the peculiar hourglass-morphology X-rays surrounding 3C 294 at z=1.8. Using International Low Frequency Array (LOFAR) da…
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…
Balmer Absorption in Iron Low-Ionization Broad Absorption Line Quasars
Karen M. Leighly, Sarah C. Gallagher, Hyunseop Choi +4
While C IV is the most common absorption line in Broad Absorption Line Quasar spectra, Balmer absorption lines are among the rarest. We present analysis of Balmer absorption in a s…
Scalable and robust wide-field facet calibration with LOFAR's longest baselines
J. M. G. H. J. de Jong, L. Veefkind, R. J. van Weeren +8
Recent work has successfully achieved sub-arcsecond wide-field imaging with high-band observations from the Low Frequency Array (LOFAR). However, the scalability of this work remai…
What drives the growth of black holes: a decade of progress
D. M. Alexander, R. C. Hickox, J. Aird +8
The last decade has witnessed significant progress in our understanding of the growth of super-massive black holes (SMBHs). It is now clear that an Active Galactic Nucleus (AGN: th…
