Simulations of cm-wavelength Sunyaev-Zel'dovich galaxy cluster and point source blind sky surveys and predictions for the RT32/OCRA-f and the Hevelius 100-m radio telescope
Bartosz Lew, Mark Birkinshaw, Peter Wilkinson +1
We investigate the effectiveness of blind surveys for radio sources and galaxy cluster thermal Sunyaev-Zel'dovich effects (TSZEs) using the four-pair, beam-switched OCRA-f radiomet…
The SKA and the Unknown Unknowns
Peter Wilkinson
As new scientists and engineers join the SKA project and as the pressures come on to maintain costs within a chosen envelope it is worth restating and updating the rationale for th…
Update on the BINGO 21cm intensity mapping experiment
Richard Battye, Ian Browne, Tianyue Chen +21
21cm intensity mapping is a novel approach aimed at measuring the power spectrum of density fluctuations and deducing cosmological information, notably from the Baryonic Acoustic O…
Preliminary Sunyaev Zel'dovich Observations of Galaxy Clusters with OCRA-p
Katy Lancaster, Mark Birkinshaw, Marcin P. Gawronski +6
We present 30 GHz Sunyaev Zel'dovich (SZ) observations of a sample of four galaxy clusters with a prototype of the One Centimetre Receiver Array (OCRA-p) which is mounted on the To…
Automating the assessment of biofouling in images using expert agreement as a gold standard
Nathaniel J. Bloomfield, Susan Wei, Bartholomew Woodham +2
Biofouling is the accumulation of organisms on surfaces immersed in water. It is of particular concern to the international shipping industry because it increases fuel costs and pr…
Localising fast radio bursts and other transients using interferometric arrays
Monika Obrocka, Benjamin Stappers, Peter Wilkinson
A new population of sources emitting fast and bright transient radio bursts has recently been identified. The observed large dispersion measure values of FRBs suggests an extragala…
Sunyaev Zel'dovich observations of a statistically complete sample of galaxy clusters with OCRA-p
Katy Lancaster, Mark Birkinshaw, Marcin P. Gawronski +15
We present 30 GHz Sunyaev Zel'dovich observations of a statistically complete sample of galaxy clusters with OCRA-p. The clusters are the 18 most X-ray luminous clusters at z > 0.2…
