LOFAR-UK 2016-2019: LOFAR-UK Compute Facility

Lead Research Organisation: University of Hertfordshire
Department Name: School of Physics, Astronomy and Maths

Abstract

LOFAR, the LOw-Frequency ARray, is the world's most sensitive radio telescope operating at metre wavelengths. It is now producing extremely sensitive and detailed images of the radio sky at these wavelengths, but the data reduction process is complex. The proposed funding allows us to maintain and expand an existing computing facility for the use of UK astronomers involved in LOFAR.

Planned Impact

See main LOFAR-UK proposal for details.

Description The LOFAR-UK compute facility was used by scientists round the UK to process LOFAR individual observations and surveys data. It underpinned the release of LoTSS data release 1, with many tens of papers on active galaxies, clusters, star-forming galaxies being produced as a direct result.
Exploitation Route Astronomers round the world are building on the newly processed data, including the original team.
