Spectral ageing in the era of big data: integrated vs resolved models
Jeremy J. Harwood
Continuous injection models of spectral ageing have long been used to determine the age of radio galaxies from their integrated spectrum; however, many questions about their reliab…
The LOFAR Two-metre Sky Survey - I. Survey Description and Preliminary Data Release
T. W. Shimwell, H. J. A. Röttgering, P. N. Best +69
The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120-168 MHz imaging survey that will eventually cover the entire Northern sky. Each of the 3170 pointings will be observed for 8 hr…
The Lockman Hole project: LOFAR observations and spectral index properties of low-frequency radio sources
E. K. Mahony, R. Morganti, I. Prandoni +21
The Lockman Hole is a well-studied extragalactic field with extensive multi-band ancillary data covering a wide range in frequency, essential for characterising the physical and ev…
The systematic spectral analysis of radio surveys
Jeremy J. Harwood, Raffaella Morganti
Current and future continuum surveys being undertaken by the new generation of radio telescopes are now poised to address many important science questions, ranging from the earlies…
FR II radio galaxies at low frequencies I: morphology, magnetic field strength and energetics
Jeremy J. Harwood, Judith H. Croston, Huib T. Intema +14
Due to their steep spectra, low-frequency observations of FR II radio galaxies potentially provide key insights in to the morphology, energetics and spectrum of these powerful radi…
