The LOFAR Two-metre Sky Survey (LoTSS) III. First Data Release: optical/IR identifications and value-added catalogue
W. L. Williams, M. J. Hardcastle, P. N. Best +38
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168 MHz survey of the Northern sky with diverse and ambitious science goals. Many of the scienti…
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 LoTSS view of radio AGN in the local Universe. The most massive galaxies are always switched on
J. Sabater, P. N. Best, M. J. Hardcastle +18
This paper presents a study of the local radio source population, by cross-comparing the data from the first data release (DR1) of the LOFAR Two-Metre Sky Survey (LoTSS) with the S…
Science with an ngVLA: Young Radio AGN in the ngVLA Era
Pallavi Patil, Kristina Nyland, Jeremy J. Harwood +2
Most massive galaxies are now thought to go through an Active Galactic Nucleus (AGN) phase one or more times. Yet, the cause of triggering and the variations in the intrinsic and o…
Science with an ngVLA: Radio Jet-ISM Feedback on Sub-galactic Scales
Kristina Nyland, Dipanjan Mukherjee, Mark Lacy +5
Energetic feedback by active galactic nuclei (AGNs) plays an important evolutionary role in the regulation of star formation (SF) on galactic scales. However, the effects of this f…
Investigating the cause of the - relation
Leah K. Morabito, Jeremy J. Harwood
The correlation between radio spectral index and redshift has long been used to identify high redshift radio galaxies, but its cause is unknown. Traditional explanations invoke eit…
Duty cycle of the radio galaxy B2 0258+35
M. Brienza, R. Morganti, M. Murgia +14
Radio loud Active Galactic Nuclei are episodic in nature, cycling through periods of activity and quiescence. In this work we investigate the duty cycle of the radio galaxy B2~0258…
Revolutionizing Our Understanding of AGN Feedback and its Importance to Galaxy Evolution in the Era of the Next Generation Very Large Array
Kristina Nyland, Jeremy J. Harwood, Dipanjan Mukherjee +19
Energetic feedback by Active Galactic Nuclei (AGNs) plays an important evolutionary role in the regulation of star formation (SF) on galactic scales. However, the effects of this f…
Remnant radio-loud AGN in the Herschel-ATLAS field
V. H. Mahatma, M. J. Hardcastle, W. L. Williams +10
Only a small fraction of observed Active Galactic Nuclei display large-scale radio emission associated with jets, yet these radio-loud AGN have become increasingly important in mod…
